application of site to site vpn

Hi all

I have a pix firewall that has a vpn site-to site with another branch. He also works as a remote vpn.

Here are the commands to use to configure the ipsec tunnel. The vpn site-to-site and client remote vpn works great.

I was wondering if the 'card crypto testmap authentication of the client LOCAL' command would affect my vpn site-to-site in anyway since only client remote vpn authentication based on the username and password sets on my firewall. Thks in advance.

TestMap 20 ipsec-isakmp crypto map
card crypto testmap 20 match address outside_cryptomap_20
card crypto testmap 20 peers set 2xx.xx.xx.xx
card crypto testmap 20 game of transformation-ESP-DES-MD5
map testmap 65535-isakmp ipsec crypto dynamic outside_dyn_map
client authentication card crypto LOCAL testmap
testmap outside crypto map interface

Hello

If it's a PIX running version 6.x, you have a command like:

xxxxxxx peer 1.1.1.1 key crypto ISAKMP xauth No.

You must add the "no xauth" counterpart, so that the L2L will not be invited for Extended (only VPN remote clients) authentication.

Hi yururuhgftdy, your vpn is only as good as the slowest connections. If you want to improve performance, update the connection from the other end.

Site to Site VPN question

Hello world

The vendor name is implemented server in our environment.

We implement VPN site-to-site.

Subnet it is interesting traffic 192.168.50.x

Server IP 192.168.50.1 - Switch1 - ASA - Site to site VPN - provider ASA.

Gateway server is on switch1 if this server requires access to the internet I need to know what config I need on ASA on my site?

I want the server to access the internet through the provider network

Concerning

Mahesh

Hello

Your crypto ACL would be:
```
ip access-list VPN-TO-VENDOR permit ip 192.168.50.0 255.255.255.0 any
```
Cryptography providers ACL would be:
```
ip acces-list VPN-TO-COMPANY permit ip any 192.168.50.0 255.255.255.0
```
All traffic from 192.168.50.0/24 out of the application interface map encryption for any destination would be sent to the seller through the VPN. It will be useful.

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.

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.

Site to site VPN question: passing a public IP with IPSEC

Hi all

I need to create a VPN tunnel site to site using IPSEC between two offices on the Internet. The offices belong to two different companies.

They gave me a series of 16 public IP addresses. One of these IP addresses is used on the ISP router and this is the next hop for my router. Another IP in the range is used on my router? s external interface (which is a Cisco 851) and he is also my site VPN endpoint. So far so good...

Here's my problem: the IP source of encrypted traffic, is a public address from within the IPs public 16 I (not the one on my router interface). The actual application that needs to send the encrypted data is a server in my local network, and it has a private IP address. The other site, expects to receive data, however, the public IP address. I used NAT between the private IP address of the server and its public IP address, but no data goes through the tunnel. Moreover, the tunnel between the two end points established without problem. The problem is that the source of my encrypted data is the public IP address and I don't know how to get through the tunnel. I enclose my router configuration.

Any help is appreciated.

The access list "natted-traffic" should say:

extended traffic natted IP access list

deny ip host 192.168.0.160 BB. ABM ABM BD

deny ip host 192.168.0.160 BB. ABM BB.BE

output

I hope this helps.

Site to SIte VPN through a NAT device

I have, I am having trouble running a vpn site-to site between two 3725 routers running c3725-advsecurityk9-mz124 - 15 T 1, that I hope I can get some help with, I am probably missing something here. The VPN ran very well when both VPN routers were connected directly to the internet and had on WAN interfaces public IP addresses, but I had to move one of the firewall inside on a private IP address. Installation is now as below

Router VPN one (192.168.248.253) - internal company network - Fortigate FW - internet-(217.155.113.179) router VPN B

The fortigate FW is doing some translations address
-traffic between 192.168.248.253 and 217.155.113.179 has its source in 37.205.62.5
-traffic between 217.155.113.179 and 37.205.62.5 has its destination translated to 192.168.248.253
-Firewall rules allow all traffic between the 2 devices, no port locking enabled.

-The 37.205.62.5 address is used by anything else.

I basically have a GRE tunnel between two routers, and I'm trying to encrypt it.

I can see counters incrementing on the ACL on both routers, so I don't know the traffic free WILL is interesting.

Here are a few debugs too

Hi Nav,

I'm happy it's working now. Your interpretation is correct. Transport mode IPSEC encrypts the payload, while tunnel mode figure the whole ip packet (original header / payload) and inserts a new ip header. Thus, the tunnel mode is used for ipsec site to site VPN and transport is used for point to point VPN ipsec. GRE is used with ipsec, all packages will be encapsulated with a GRE header first, so, essentially, this is a point to point VPN ipsec.

The problem that you are having with tunnel mode, the router's package is going to be wrapped with the header 192.168.248.253 GRE source 217.155.113.179 destination. The whole package is then encrypted and a new header is added with the same source/destination. This new header will be coordinated by the FW, but not incorporated or encrypted GRE header. When the packet arrives at Router B, after decrypt them the package, router B will see the GRE header, which is different from that of source/destination tunnel she uses. This breaks the GRE tunnel and the routing between router A and router B Protocol.

HTH,

Is site to site VPN with sufficiently secure router?

Hello

I have a question about the site to site VPN with router.

Internet <> router <> LAN

If I have a VPN site-to-site configured on the router above with another site. I configured to block incoming Internet connections with the exception of VPN to access list. What are the risks of the LAN is exposed to threats from the Internet? Recommend that you put in a firewall between the router and the LAN, or replace the router with a firewall?

Thank you

Hi Amanda,.

Assuming your L2L looks like this:

LAN - router - INTERNET - Router_Remote - LAN

|-------------------------------------------------------------------------------|

L2L

Traffic between the two local area networks is protected by the VPN tunnel. It is recommended to use the recommended security (strong encryption settings) to ensure that the encrypted traffic would not be compromised through the Internet.

On the other hand, if you talk about outbound plaintext to the Internet, as when a user acceses google.com, then you just make out traffic, but never allow all incoming connections.

If you want to protect your network with advanced security as a FW features, you can consider ZBF, which is the available in IOS Firewall/set function:

Design of the area Guide of Application and firewall policies

If you consider that this is not enough, check the ASA5500 series.

IPsec site to Site VPN on Wi - Fi router

Hello!

Can someone tell me if there is a router Netgear Wi - Fi that can form IPsec Site to Site VPN connection between 2 Wi - Fi routers via the WAN connection?

I know that this feature exists on the Netgear firewall, but can you have the same function on any Wi - Fi router?

See you soon!

Michael

I suspect that.

Thank you very much for the reply.

See you soon!

Site to site VPN, I need all internet traffic to exit the site.

I have 2 sites connected via a pair of SRX5308

A = 192.168.1.0/24

IP WAN = 1.1.1.1

B = 192.168.2.0/24

IP WAN = 2.2.2.2

Now what I need to do, is to have all traffic from B to go to the site one even traffic destined to the internet. That is, I need internet traffic out of our network with the IP 1.1.1.1, even if it is from the network B.

On my I have set up a route 1.1.1.1 of the ISP, then a value by default 0/0 to 192.168.1.1 it ASA knows how to get to the peer VPN is a more specific route, but sends everything above the tunnel, at the remote end which then hairpin of ASA routes internet outside its own WAN port traffic.

I can understand though not how to so the same thing on the pair of SRX5308 they either don't raise the tunnel or internet route to the local site address B.

Anyone have any ideas?

I need to do this because we are logging and monitoring of internet traffic to A site via tapping from upstream to various IDS solutions and will not (cannot) reproduce this to all our remote sites.

Thank you

Dave.

After some more thought and testing I came up with a workable solution to my own problem. I'll share it here in case it can help others.

(1) use the wizard at both ends to implement a normal VPN that connects the two segments of network 192.168.1.0 and 192.168.2.0

(2) go to site VPN - VPN policy remote router192.168.2.1 and click Edit

(a) disable Netbios

(b) select "None" from the drop-down list the remote IP address.

(c) to apply the change

3) go to the VPN-> VPN policy on the head end site (192.168.1.1) and click Edit

(a) disable Netbios

(b) select "None" from the drop-down list the local IP address

(c) to apply the change

Now all the traffic wil go down the VPN tunnel and exit to the internet on the site of head end. Hope this helps others with the same question.

Site to Site VPN on AZURE

I have a VPN site-to-site existing on Azure and Azure a new subnet created on the local network that must be able to reach.

I added the new subnet within azure for the VPN and add a static route on the RRAS server win 2012 for routing.

On the initial installation of a RRAS-Site VPN site (I didn't configure it) I think the interesting traffic specified must be sent through the VPN Tunnel, but I knew how to specify the new subnet via RRAS, I don't want to delete and re-create the VPN Site to Site.

Y at - there anyone who can help please.

Thank you

Philippe

IPSec Site to Site VPN Solution needed?

Hi all

I need a solution to provide full connectivity to one of my clients. I created two IPSEC Site to Site VPN, one between the INFO and RITA and second between NIDA and RITA. I can access RITA machine that is 172.16.36.101 at the INFO and 10.0.0.5 to NIDA.

Now, I need to give access to my customer INFORMATION to direct NIDA 10.0.0.5 without established VPN machine to NIDA 10.0.0.5 of 172.16.36.101 access.

Could you please give me the solution how is that possible?

Concerning

Uzair Hussain

Hi uzair.infotech,

Looks like you need to set up a grouping between the 3 sites, at the end of that your topology will look like this:

INFO - RITA - NIDA

You can check this guide that explains step by step how to configure grouping:

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.

Federico.
