PIX Site to Site VPN to aid to specific port

Good day to all!

I know that to have establish a site to site VPN using 2 PIX firewall, it should be noted the interesting traffic on both sides. Usually, we make the following statement:

accessList AllowedTraffic ip 192.168.2.1 allow 192.168.3.1

But I thought what happens if specify us specific ports on the

The ACL that is used for interesting VPN as HTTPS traffic? Like the one below:

Acccess-list AllowedTraffic tcp 192.168.2.1 192.168.3.1 eq 443

Comments would be nice...

Thank you...

Chris

Here are my configs when I tested it. I hope this helps! If Yes, please rate.

Remote monitoring Pix on IPSEC site to site VPN

I have a few 501 s PIX that connect through the VPN site-to site. We use Orion NPM and I can't add monitoring. I was able to add remote routers that connect through site-to-site VPNs. I guess that the rules of the Pix security/NAT prevent that. The configuration of the remote Pix is attached.

Cisco 3640 to the PIX 501 site 2 site VPN performance specifications.

I intend on creating a site-2-site VPN in Star configuration with a Cisco 3640 as the hub and PIX 501 at the remote sites. My question is around the plug that I read.

.

The specifications for a PIX-501-BUN-K9 tell PIX 501 3DES Bundle (chassis, SW, 10 users, 3DES).

.

A question is what really "10 users. Which is the limit of the number of concurrent sessions, I have on the VPN at a given time, or that it means something else?

.

I also read the specs say that the Maximum number of VPN tunnels that can support a PIX 501 is 5. Because I'm not going to make a tunnel between the PIX 501 at the remote site and the 3640 on the central site, I think I would be OK. Is that correct or is the max value talk the maximum number of concurrent sessions on the tunnel tunnels?

.

Thank you.

UDP traffic always creates a session in the PIX so that the return traffic will be allowed in. The UDP timeout is 2 minutes but IIRC. If you go around NAT with a statement of "nat 0" should not create an xlate I think.

The real time is hard to say really, probably around 2 minutes for a UDP-only user, you would probably make a few 'local sho' orders on the PIX to really see for sure however.

Troubleshooting IPSec Site to Site VPN between ASA and 1841

Hi all

in the past I've implemented several VPN connections between the devices of the SAA. So I thought a site link between an ASA site and 1841 would be easier... But it seems I was mistaken.

I configured a VPN Site to Site, as it has been described in the Document ID: SDM 110198: IPsec Site to Site VPN between ASA/PIX and an example of IOS Router Configuration (I have not used SDM but CCP).

I have run the wizards on the ASA with ASDM and the current IOS version 15.1 1841, with CCP.

It seems to Phase 1 and 2 are coming although my ASA in ADSM reports (monitoring > VPN > VPN statistics > Sessions) a tunnel established with some of the Tx traffic but 0 Rx traffic),

On the ASA:

It seems that the routing on the 1841 is working properly as I can tear down the tunnel and relaunch in scathing a host on the network of 1841, but not vice versa.

Trounleshoot VPN of the 1841 report shows a message like "the following sources are forwarded through the interface card crypto. (172.20.2.0 1) go to "Configure-> routing" and correct the routing table.

I have not found an error on the 1841 config so if one of the guys reading this thread has an idea I appreciate highly suspicion!

It's the running of the 1841 configuration

Joerg,

ASA receives not all VPN packages because IOS does not send anything.

Try to send packets to the 1841 LAN to LAN of the ASA and see is the "sh cry ips its" on the 1841 increments the encrypted packets (there not)

The problem seems so on the side of the router.

I think that is a routing problem, but you only have one default gateway (no other channels on the router).

The ACL 100 is set to encrypt the traffic between the two subnets.

It seems that the ACL 101 is also bypassing NAT for VPN traffic.

Follow these steps:

Try running traffic of LAN router inside IP (source of ping 192.168.37.x 172.20.2.254) and see if the packages are not through the translation and obtaining encrypted.

I would also like to delete 100 ACL from the inside interface on the router because it is used for the VPN. You can create an another ACL to apply to the interface.

Site to Site VPN filter

I've set up a site to site VPN and I can't seem to get the VPN filter works. I've followed this document:

http://www.Cisco.com/image/gif/paws/99103/PIX-ASA-VPN-filter.PDF

I created an ACL and created an ACE with only traffic I want to allow. Then, I went to the site to site group policy and apply this filter. However, I can still ping remote network from a customer who should not be allowed. Remote network is 192.168.2.0/24.Here is my partial config:

permit Test access extended list ip 192.168.2.0 255.255.255.0 192.168.1.2 host
Trying to deny a range ip extended access list

Group Policy internal Test
Test group policy attributes
value of VPN-Filter Test

tunnel-group Test_tunnel type ipsec-l2l
attributes global-tunnel-group Test_tunnel
Group Policy - by default-Test

Hello

First of all I would like to clarify that the group name used for one site to the other tunnel tunnel must be the ip address of the host "at least for the tunnels l2l static" it's tunnel-g were you must apply this "Test" group policy, configuring the filter seems perfect, but you must make sure that you apply the strategy of Group accordingly. Now, once you apply group policy to the correct you have to bounce the tunnel tunnel-g otherwise the new filter will not take effect, you can use the command "erase the crypto ipsec his counterpart x.x.x.x" generate some traffic and bring up the tunnel is again he should have the filter.

If you apply correctly and bounce the tunnel it will work.

You can check if the filter is applied with the command "show vpn-sessiondb detail l2l" and find the name of the ACL

Best regards, please rate.

Creating a site to site VPN

Hi guys,.

I need to know if it is possible to create a site to site vpn and to put an end to our headquarters, where we have an asa5500. Remote Desktop can have a router from cisco 800 series running VPN easy?

I see no reason why not. I currently have multiple VPN from site to site of 1800, the routers of the 800 series terminated on PIX 515, which is a device less than your ASA5500. Give it a go and see.

Site to site VPN with router IOS

I want to create a VPN site-to site on the Internet. On the remote site, aside from the VPN to the head office, there should be no traffic not allowed in internal from the Internet to the network and that there should be no traffic from the internal network to the Internet allowed. The internal network will run a private 192.168.x.x address range.

I'm going to use a Cisco 2811 router integrated of services on the remote site and this will last an IPSec VPN that will end a hub at Headquarters. I understand that this router has an IOS and IPS firewall built in.

Would I be right in thinking that because I don't want to have access to the Internet (except VPN) or should I configure IOS firewall features on the router? And there is no point in the configuration of the features IPS wouldn't?

My thought is that only an entry in list of unique access to deny pi a whole applied inbound to the interface that connects to the Internet would be the best strategy. I think that the command "sysopt connection permit-ipsec" should allow the VPN to form even with the ip address to deny any any ACL (or is it just a Pix command? If Yes, then I have to allow ESP and UDP 500 (ISAKMP) from the public address of the hub at Headquarters to allow the VPN to form wouldn't I?).

Think I'll probably expand slightly the access list to allow the icmp Protocol, ssh and https traffic from the IP address of firewall seat outside so that I can monitor the remote site and access it safely if the fail VPN.

And I wouldn't need one access list on the interface connected to the internal network I would like because the range of addresses would be not routable, so they would not be able to initiate connections to the Internet (all the trffic to the remote site is specified under a valuable traffic to bring up the VPN)

Use one of the IOS Firewall inspect commands or the IPS would be useless and have no effect in this case wouldn't it?

I really just need to know if the ip address to deny any any ACL on the external interface on the remote site is the best solution (and the simplest), and whether it will be safe.

We used to use fiewalls Pix for remote VPN site to site, Amazon refuse incoming connections on the external interface by default but now I have been informed that these series 2800 routers will be used later, so I would get my thoughts straight and be able to build safe to do the same work all existing PIX are doing (they are all installed for just the VPN at Headquarters as in) the first paragraph).

I would like any advice or thoughts on the subject. I don't know there must be a ton of people who put routers for the same purpose.

Thank you in advance.

Pete.

I did a lot of implementations site VPN to another using IOS routers. They work very well. Based on my experience I offer these comments and I hope that they will help you:

-you don't want a list of incoming access on the external interface, but you want more in it than simply refuse an ip. There is no permit-ipsec sysopt connection in IOS so you want to certainly allowed ISAKMP and IPSec/ESP. I suggest that you also want to allow SSH. I would like to allow ICMP but only starting from the address space of the network head end. I do not allow HTTPS since I generally do not allow the http server on the router. If you want HTTPS then certainly enable it. To facilitate the ping and traceroute on the remote I frequently allow icmp echo-reply, timeout and unreachable port from any source.

-I want to put an inside interface access list. There are certain types of traffic that I don't want to send from the Remote LAN. I have usually refuse any trap SNMP or snmp for LAN devices and refuse out of the local network icmp redirects. I also often configure RPF controls inside interface to catch any device which is misconfigured.

-If you want to allow SSH when the VPN is not active (and I highly recommend that you do) then you will probably need to configure at least 1 (and maybe more) users and password of the router ID. And you want to configure authentication on the vty use local authentication if the head end authentication server is not available.

-I'm not clear from your description if you plan to run a dynamic routing via the VPN Protocol. I wish I had a dynamic routing protocol because I want to announce a default route to the remote control via the VPN. I do not locally configure a default route on the remote router. This way if the VPN tunnel is up there is a default route pointing to the tunnel and if the VPN tunnel is not up then there is no local route by default and users on the remote database can not access the Internet. It is a simple and very effective method to ensure that all user traffic must pass through the central site.

-regarding the routes defined on the remote router, my approach is that I define a static route for the endpoint of the tunnel to allow the tunnel to implement and I set up static routes for the subnet to the head of line I can SSH. And I do not configure other static routes the on the remote router.

-You probably want to disable cdp on the external interface and also to disable the proxy-arp (and I don't make any ip unreachable).

-There is frequently a problem when using VPN site-to-site with fragmentation. If a device on the local network sends a frame of maximum size, and then the router needs to add additional headers for IPSec, then the frame is too large and requires fragmentation. I like to use tcp adjust-mss ip to control the chunk size for TCP traffic and avoid any problems with fragmentation.

-I don't think you want to set up the firewall or IPS from the features of IOS on the 2811.

I hope that your application is fine and that my suggestions could be useful.

[edit] after posting my response, I read through your post again and realize that you make to a VPN concentrator. The approach I have proposed on the execution of a routing protocol works for me because I usually have a router IOS in mind. It would not work to connect to a hub.

Using the same set processing on several site to site VPN tunnels

Hi all. I have a rather strange situation about site-to-site VPN tunnel.

On the one hand, I have a PIX 501 and on the other end an ASA5505 and a tunnel set up between them.

The problem is that on the side of the PIX, I can't establish a tunnel, but when the traffic starts on the side of the ASA the tunnel established as usual.

I checked the configurations on both ends and keys, passwords, mirror that LCD seems OK. The only thing that comes to my attention, it's that I have the same set of transformation used for 2 different tunnel on the side of PIX.

Can I use the same set of transformation on several tunnels or should I set a different transformation for each tunnel? Could be the source of the problem?

Use it on PIX

card crypto set pfs group2

Or on ASA, use:

card crypto set pfs Group1

Design site to Site VPN w/NAT traversal issue

Hi, I have a number of site to site VPN that end on a PIX. I intend to migrate these VPN to a router that sits on a demilitarized zone connected to the PIX. Before doing that I'm going to set up a private network new virtual to end on the router but I also need than VPNS that end on the PIX to be not affected.

If I configure NAT traversal on the PIX, affected my other VPN?

Thanks in advance

DOM

Hi Dom,

Why do you want to configure NAT-Traversal on PIX, if you wish to terminate your VPN router (which is on the DMZ).

Do you do any NAT on PIX thru the router?

If you want to configure NAT-Traversal, it must be configured on the end (on the router in your case) devices.

Example:

When a user with Cisco client or Cisco router behind NAT wants to connect to another device (such as PIX, ASA, or router) NAT - T must be configured on the machine (which will be the PIX or ASA)

Hope that helps.

Hello

Newspapers, I see you are using a VPN 3000 Concentrator as the remote vpn end point. Now, also of the debugs next section is interesting:

local (identity) = 70.91.20.245, distance = 208.249.117.203.
local_proxy = 0.0.0.0/0.0.0.0/0/0 (type = 4),
remote_proxy = 206.200.22.0/255.255.255.0/0/0 (type = 4)

-Looks like our traffic interesting PIX and the hub are not mirrors of each other, and does not. Can you please paste the PIX here cryptographic access lists, so that I can analyze the entries.

-Also, please make sure that you have followed all the steps during the vpn configuration according to the following links:

If your PIX is running at version 7.x and more: http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a008064a06f.shtml

If your PIX is running version 6.3.x: http://www.cisco.com/en/US/products/hw/vpndevc/ps2284/products_configuration_example09186a00800949d2.shtml

Once you check the config on PIX and concentrator, please provide me with the output of "sh cry isa his" and "sh cry ipsec his ' of the PIX. With this release, we can continue to troubleshoot if there is more questions.

Let me know if this can help,

See you soon,.

Connectivity between two site to site VPN

I have two remote sites that each connect to our main office using a site to site VPN. Remote offices have 831 routers. The main office has a PIX 515.

A remote office is 192.168.15.X and the other is 192.168.100.X. The main office is on a 10.X.X.X network.

Each remote office can contact the office with no problems. However, they cannot communicate with each other at all and I need this to work. I just want to be able to access the network 192.168.100.X network 192.168.15.X through the VPN tunnel that is already set up between each remote desktop.

I tried to add the other network to the ACL for the tunnel, but that did not work. I feel I'm missing something simple.

For example, the following ACL initially.

Note access-list 103 IPSec rule

access-list 103 allow ip 192.168.15.0 0.0.0.255 10.0.0.0 0.255.255.255

I added this line to this LIST.

access-list 103 allow ip 192.168.15.0 0.0.0.255 192.168.100.0 0.0.0.255

But that did not help.

Thanks in advance.

Hello

What code are you running on the Pix. Talk to talk IPSEC connectivity is supported only in version 7.0 and higher.

Enhanced support has spoke-to-Spoke VPN

Version 7.0 (1) improving support communications a spoke-to-spoke (customer-to-customer) VPN, providing the ability to traffic to enter and exit the same interface. In addition, remote access to splitting tunnel connections can be completed on the external interface of the security apparatus, enabling traffic destined to the Internet for remote user VPN tunnels to leave on the same interface as it happened (after that the firewall rules have been applied).

The same-security-traffic command permits traffic to enter and exit the same interface when it is used with the keyword a spoke-to-spoke VPN using intra-interface. For more information, see the section "Allows Intra-Interface traffic" in the in the command line Configuration Guide Cisco Security Appliance.

NAT and Site to site VPN

Hi all

We currently have a PIX in our local network. There is a Site to site VPN tunnel between this PIX and another network abroad.

We have several networks in our local network.

The VPN tunnel is on a single network: 192.50.175.0 / 24.

and the network of the other site is:

192.100.24.0 21

Part of the configuration:

inside_nat0_outbound ip 192.50.175.0 access list allow 255.255.255.0 192.100.24.0 255.255.248.0

NAT (inside) 0-list of access inside_nat0_outbound

As I said before, we have several networks.

In particular, we have 192.50.160.0/24 too.

And we would like that this network can use the VPN tunnel also.

But the other site does not want to carry our another network in their LAN.

They suggest we 192.50.160.0 NAT / 24 to an IP address on the 192.50.175.0 / 24, users in a network 192.50.160.0 / 24 can also use the VPN tunnel.

Do you know if it is possible to do it with my PIX? And how?

It's a PIX-515-DMZ, v6.3 (5).

Any help would be appreciated!

Thank you

Good point. You can be good then.

Site to site vpn user name?

For several years I have implemented no - DMVPN IPSEC VPN. At the time, it was 515 s Pix. If I remember correctly, I could set up is a site to site vpn (in which the phase I and phase II card was entered, PSK, etc.) a user remote vpn (where meanings would be implemented with XAUTH for the user credentials, and I think security settings of group for different users). It comes before DMVPN, who simplified a lot of it.

Anyway, now I have a colleague who bought a RVS4000 with a view to setting up a vpn site-to site with BeeVPN, a site that allows him to work around his ISP followed. When he asked BeeVPN sheet on how to set up his RVS4000 as one endpoint of IPSEC for site to site vpn, they responded with prison to enter his user name and password as the group name. What's a sense? Shouldn't an address of peers, encryption/auth/various-hellman, settings etc. and PSK everything that is required for a vpn site-to site?

Furthermore, I realize that he may have another problem with his dynamic ip address. But I was hoping I could get help on the basics first.

Thank you very much

You are right.

A Site VPN PIX501 and CISCO router

Hello Experts,

I have an at home test lab, I set up a site to site vpn using a router Cisco PIX501 and CISCO2691, for configurations, I have just a few links on the internet, because my background on VPN configuration is not too good, for the configuration of routers, I followed this link:

www.Firewall.CX/Cisco-Technical-Knowledgebase/Cisco-Routers/867-Cisco-ro...

and for configuring pIX I just use the VPN Wizard of pix. All confgurations but ping failed. Hope you can help me with this, don't know what to do here (troubleshooting).

Joint here is the configuration of my router, topology, as well as the pix configuration. Hope you can help me with this. Thanks in advance.

Hi Mark,

I went in the Config of the ASA

I see that the dispensation of Nat is stil missing there

Please add the following

access-list allowed sheep ip 192.168.1.0 255.255.255.0 172.21.1.0 255.255.255.0

inside NAT) 0 access-list sheep

Then try it should work

Thank you

Site-to-Site VPN IPSEC falls intermittently

Site-to-Site VPN IPSEC falls intermittently

I am currently having a problem with a VPN from Site to Site traffic not only not intermittently. When the problem occurs, I can't Ping the remote site to the AC Site. But I can solve the problem by Pinging from HQ at the Remote Site. My network is currently configured as follows

-------HQ------

7.0 (4) version of pix 515 with card Ethernet 4 ports.

Outside of the interface connected to the Broadband DSL link.

Outside2 Interface connected to the second link DSL broadband

-Distance-

I have 4 Remote Sites. 2 sites connect you to each connection to wide band at HQ to spread the load to HQ

6.3 (5) pix 501 version

# The problem #.

All VPN establishes successfully to the HQ Pix

Intermittently, a remote site will report that they cannot connect to servers/services in the HQ. When I do a show crypto ipsec's and see the crypto isakmp his headquarters there is no entry for the remote site. However when I do the same on the remote site there is an entry for the HQ. With debugging on the remote site pix I try to ping from a pc to the HQ server and I get the following (see below). If I do a "ipsec Isakmp security association claire crypto ' and ' clear crypto ipsec his ' on the pix of remote site, then I can successfully ping all servers in headquarters.

This problem seems to have taken place only when I upgraded the pix of a 501 to 515 and added another 2 remote sites and a second broadband, as described above. I'm afraid that there is a problem with software version 7 Pix. Any advice would be greatly appreciated.
