Question - VPN on PIX
Our PIX firewall allows any set up inside. In the past, we have tried to establish a VPN connection from inside our network to a hub on the Internet VPN and it did not work. We were told that do VPN behind a firewall is not possible (I don't remember who said that). However, last week we had a customer VPN to their network through our firewall. I don't have the details on the equipment or Protocol. Technically, I would like to know what can and cannot be done from the inside using VPN and to understand the reasons. We went through a few updates on the PIX from v5.0 to v6.2, and I suppose this may have something to do with it. If someone could help or point me to documentation that explains this in detail, it would be highly appreciated.
Thank you!

The big problem with IPSec through a firewall is not so much the filtering (specific protocols can easily be let go), but generally the NAT'ing or more precisely, the PAT'ing (Port Address Translation). VPNS use IPSec or PPTP usually, that use a protocol that is not TCP or UDP based (ESP and GRE respectively). Whe ndoing PAT however, it relies on a TCP or UDP port number to differentiate the different sessions and so when a protocol arrives who doesn't have it, it is usually deposited by the PAT device ' ing.
Many VPN solutions are now a feature called IPSec via UDP, or via TCP or transparency IPSec IPSec, or whatever you want to call. Basically, the VPN client and the hub encapsulate IPSec ESP packets in a packet UDP or TCP depending on the implementation, this p [rescue can be PAT would have correctly and everything works fine. Your client was probably using something like that.
PIX 6.3 code will support IPSec and PAT, but only for an internal IPSec session. You are the best solution is to see if any VPN software you are using supports a kind of UDP or TCP encapsulation, then you'll be off and running.

VPN concentrator + PIX on LAN-> customers can not reach local servers
Hello
I have a problem wrt. remote access clients coming via a VPN3000 concentrator and trying to access local servers.
For the topology:
The internal network is 10.0.1.0/24. It connects with the outside world, as well as via a PIX DMZ; the PIX has 10.0.1.1 in the internal network.
On the same LAN (internal), I have the VPN concentrator for the inside address 10.0.1.5. It assigns addresses in the 10.0.100.0/24 range to the
VPN client-PCs.
I can sucessfully connect using the VPN client SW to the hub, i.e. remote access clients out addresses
the 10.0.100.0/24 range.
The problem: access from VPN clients to internal network is * not * possible; for example, a customer with 10.0.100.1 cannot connect to
internal to the 10.0.1.28 server.
To my knowledge, this is a routing problem because the server (10.0.1.28) has no idea on how to reach customers in
10.0.100.0/24. The only thing that the server is a default static route pointing to the PIX, i.e. 10.0.1.1.
So I set up a static route on the PIX for 10.0.100.0 pointing to the hub-VPN, that is
Mylan route 10.0.100.0 255.255.255.0 10.0.1.5 1
This does not solve my problem though.
In the PIX logs, I see the entries as follows:
% 3 PIX-106011: deny entering (no xlate) tcp src trainee: 10.0.1.28 (atlas) / 445 intern dst: 10.0.100.1 (pending) 1064
The PIX seems to abandon return packages, i.e. traffic from the server back to the client
To my knowledge, the problem seems to be:
Short traffic VPN - client-> Concentrator VPN-> Server-> PIX - where it gets moved.
My reasoning: the PIX only sees the package back, i.e. the package back from the server to the client - and therefore decreasing the
package because he has not seen the package from the client to the server.
So here are my questions:
(o) how do I configure the PIX that I be connectivity between my remote VPN clients (10.0.100.0/24) and
computers servers on the local network (10.0.1.0/24)?
(o) someone else you have something like this going?
PS: Please note that the first obvious idea, installation of static routes on all machines on the local network is not an option here.
Thank you very much in advance for your help,.

Hello, PIX the because can not route traffic on the same interface (prior to version 7.0 anyway), I suggest you two places your hub to the outside with the inside of the legs on a zone demilitarized or (if you can not do a makeover of the network) you remove your pool with 10.0.100.0 - addresses and create a pool with 10.0.1.0 - addresses which is a part of the address space. No, NOT all. A little book that it is not used inside.

Login problem VPN on PIX on the side of the inside of the n/w
I am tring to connect to the vpn server (pix) outside my laptop within the network.
I have routed ip vpn on pix515 and fine ping pix.but not able to ping of 3550 switch and computer laptop.
How to get the vpn ip Switch? as I don't know the mask of the ip...
I would also like to know... is their something extra that I need on pix or 3550?
Hello!
-What is the default gateway of your laptop?
-You do any kind of NAT on the PIX? What is NAT PAT, static or normal?
-Can you ping the inside of the PIX of the laptop?
There could be several problems to solve here.
(1) first of all, make sure that your laptop has access to the internet
(2) If you want to ping him make sure internet you have an ACL on the PIX like the one below:
i.e.
Allow Access - list icmp an entire TEST
TEST group access in the interface outside
Also make sure you have no access list applied inside the PIX
-Now, can you connect at all?
-When you connect to? Another PIX? Router? Hub?
If you pass by PAT make sure that you have this command on the PIX:
"fixup protocol esp-ike.
Please let me know if you can answer my questions, in this way, it would be easier to help you.

Information on the routing of traffic of the client VPN to PIX.
Hey all,.
I could follow the VPN Wizard included in the PDM and able to connect with the VPN Clients for the PIX. But I'm looking for more information about how the routing is done.
For example, my remote is 67.71.252.xxx and my inside is 192.168.1.xxx. But if I connect via VPN to PIX Client, all data is transferred through my VPN to PIX and then trying to get out to the Internet.
I'll settle for data goes 192.168.1.xxx for transit through the VPN. This configuration made via the PIX or is it the responsibility of the Client machine to set up rules of the road?
All links to the guides to installation, or technical notes would be great.
Thank you inadvance.

Hello
I think the key word you are looking for is "split tunneling". This can be validated on the PIX using the vpngroup split access_list tunnel GroupName command.
"Split tunneling allows a remote VPN client or encrypted simultaneous Easy VPN remote access device to the corporate network and Internet access. Using the vpngroup split-tunnel command, specify the access list name with which to associate the split tunneling of traffic. "
In this example configuration: http://www.cisco.com/warp/public/110/pix3000.html, note that the same access list is used to "nat 0" and split-mining:
access-list 101 permit ip 10.1.1.0 255.255.255.0 10.1.2.0 255.255.255.0
(Inside) NAT 0-list of access 101
vpngroup vpn3000 split tunnel 101

Hello
I need to create a site to site VPN, I have in mind a PIX 515e. Behind it is a network of win2k with a domain controller for authentication. Users of the remote site must be attached to authenticate to this DC via a VPN.
The two sites to connect to the internet by modem cable and the remote site will have up to 10 users behind the PIX/VPN.
Here are my questions:
What kind of material PIX the remote site needs? A 501/506, or something else.
Do I need a VPN concentrator, etc. to the head of line?
How the hell i make it work?
Sounds simple right? I appreciate a lot of help because I am a little confused. Thanks in advance.

VPN to PIX, Win2K, Active Directory - where to start?
Hello world.
I am waiting the arrival of a PIX 515 and 501 for firewalls and creating VPN between my main site and a remote location. Remoteness is having a LAN installed but will not have a real Win2k domian while the main site is an area complete with exchange and AD win2k. The two site will connect to INet w / cable modems.
Here's the question:
Is it possible to have this remote site to be part of my site main area via the VPN? Can I set up a server on the remote site to replicate AD to, in which case the VPN is stopped for some reason any. Do I need to open ports on the firewall or not because it will be on a VPN?
Is it an easy thing to do? Is a beginner at the top of his head?
Thanks in advance for any advice.
Marc
No router required - basically, everything will be static routed - your customers, regardless of the site, will have the pix as the default gateway. each pix will have a default gateway configured, by you, by a statement of 'road '. Each pix ACL crypto will also act as a static route through the tunnel to the other pix

Location 1: (192.168.1.0/24)
Situation 2: (192.168.2.0/24)

192.168.0.0/24 to 192.168.3.0/24 ezvpn IPSEC
Question:
Is it posible to connect Location1 and Location2 via Pix, or Location1 and Location3?
On encryption ACLs on each location of traffic destined to another location is included for the encryption process.
for example, location1 acl:
Access 100 per 192.168.1.0 255.255.255.0 192.168.0.0 255.255.255.0
Access 100 per 192.168.1.0 255.255.255.0 192.168.2.0 255.255.255.0
Access 100 per 192.168.1.0 255.255.255.0 192.168.3.0 255.255.255.0
other locations have a similar LCD-s
There is no problem to access locations 192.168.0.0/24, but traffic between sites does not work.
I think that pix encrypt packets outside ariving.
I know, it's possible on IOS with IPSEC over GRE tunnels with some routing, but PIX?
Republic of Korea
Hi Rok-
Allows traffic between VPN sites does not currently work with Pix OS 6.3.4 and earlier. Code pix 7.0, which will be published later this year, will enable traffic between the same interfaces of VPN security level. This will allow talked to talk communication. I have configured the week last with Pix 7.0 beta code, so I know this is a new feature and it will work.
IOS does not have this limitation with IPSec. The GRE is not required to IOS to make communication speaks to talk work, although it can be used.
I hope this helps you understand what is happening.
Please let us know this that followed by questions that you have.
Thank you!

I got some new PIX 515E security infra-red and I had sex 2 questions about everything I tried. I installed a 5 port switch inside and cannot ping anything from the console. I have a computer on the switch, and he is able to ping other devices on the switch, but not the PIX.
What I find strange is that when I try to ping from the inside interface on the PIX of one inside computers, PIX displays the MAC address of the computer inside in the arp table.
My goal is to upgrade the PIX to ver7.0 but I can't do so until I can solve this problem.
Here are some information among the PIX.

Run the command:

With this command, the device turns into the 'Active' from a perspective of failover state. It will work after that.
See you soon.

remote offices VPN to PIX then Internet
you have a question: my remote desktop uses Cisco VPN client to the PIX firewall central, so we access the Internet from there. What we call this function and how config it? Thank you very much.
It is not currently possible with the PIX, unless your Internet connection is through a proxy.
The PIX will not allow the same coming IP packet and then back on the same interface. However if the client connects to a proxy within the network while proxy connects to the Internet that works.
Another way would be to use the split tunneling enables VPN client to connect to the PIX, bound to the internal network traffic is via the tunnel, while the unencrypted Internet traffic goes directly to the local internet connection.

IPSEC VPN between Pix 515E and 1841 router
Hi all
BACKGROUND
We have implemented a site to site VPN IPSEC between a Pix 515E 8.0 operation (4) and an 1841 using static IP addresses at both ends. We used CCP on the router and the ASDM the pix to build initial tunnels. Now the site with the router is evolving into a dynamic IP address from the ISP so we have implemented dynamic DNS to update dynamic IP address.
PROBLEM
The problem is that ASDM will not allow us to set a domain as the address of peers, it will not accept an IP address. We believe that the solution will be to remove the static Crypto map and replace it with a dynamic Crypto map on the side of Pix. Our questions are simply; is this the best solution? can change us the original static list or is it better to delete and make a new dynamic encryption card? Y at - it a shortcut to change the config command-line? This is a real network, so just check it out before make us any changes on the live kit.
Any help much appreciated.
You don't have to change anything when the peer-address changes. The dynamic crypto map aims to take dynamic peer connections. The only thing to remember, is that only the dynamic peer can initiate the connection. And you reduce your security if you use Pre-Shared key that now you can use a generic-PSK character.
As I remember, the PIX / ASA does not support the dynamic use of FQDNs for peer-resolution. This feature is supported in IOS.
For a feature, it would be preferable to static IP addresses on both sides.

Client VPN on PIX needs to access DMZ
VPN clients 3.5 ending PIX 6.X cannot access hosts on a PIX DMZ interface. Journal reports of error that there is no 'translation group available outside' for the subnet of the VPN Client (from the vpngroup pool).
I should add the VPN client subnet to a nat (outside) device?
Can I add it to the nat inside?
Can I just add static to the DMZ hosts within the subnet interface because VPN clients can access the inside hosts?
(I have the subnets in the nat 0 sheep ACL)
Thanks and greetings
JT
You'll need to add is nat 0. You say in your () you have an acl sheep, for the perimeter network or the inside interface? You use the same access list to the sheep inside and dmz? You should separate if you use separate access list. Is your pool of client on a different subnet than your home network and dmz? It must be something like this:
Customer IP local pool 192.168.1.1 - 192.168.1.254
IP, add inside 10.10.10.1 255.255.255.0
Add 10.10.20.1 dmz IP 255.255.255.0
access-list sheep by 10.10.10.0 ip 255.255.255.0 192.168.1.0 255.255.255.0
nonatdmz list of access by IP 10.10.20.0 255.255.255.0 192.168.1.0 255.255.255.0
NAT (inside) 0 access-list sheep
NAT (dmz) 0-list of access nonatdmz
If this is correct then clear x, wr mem, reload. I hope this helps.
Kurtis Durrett
PS
If he did not, only can recommend the upgrade your client and pix because that is exactly how it should look, and if its does not work you are facing an additional feature you want.

It seems that I have problems similar to many others in the connection of remote clients to a PIX 515E.
Currently, I have tried both the client VPN Cisco 3.6 and 4.03 without success. Users are authenticated very well and the customer, you can see that their assigned an address etc but they are unable to access the internal network. The crypto ipsec his watch HS no encrypted traffic has affected the Pix as its...
within the State of the customer etc., it shows that packets are encrypted so I'm at a bit of a loss.
I have also a problem with pptp connections - this seems to differ between the BONES on the client but Win2K machines can connect and get checked etc but again failed to connect within the networks. These could be linked?
My current config is: (change of address, etc.)

Sink us our PIX 525 s our VPN service. The PIX is currently give IP addresses to the IP VPN.
I put this IP address range in its own VIRTUAL LAN? I can a PIX with DOT1Q trunk on the switch?
You could put the range of client IP addresses in its own VIRTUAL LAN, but make sure you announce this route to your core network, via the static route.
802-1-q is also supported in 525 platform:
Virtual-based networks VLAN virtual interfaces
Provides greater flexibility in the definition of policies of security and global integration in switched network environments supporting the resulting creation of logical interfaces of the IEEE 802 VLAN tags. 1 q and creating security policies based on these virtual interfaces
Supports multiple virtual interfaces on a single physical interface through trunking VLAN
Supports several trunks VLAN by Cisco PIX Security Appliance
Supports up to 10 VLANS on Cisco PIX 525 security equipment
