PIX 515E - two outside interfaces - one for just vpn

Posted on 2004-09-29
Medium Priority
Last Modified: 2013-11-16
I've added a second DSL line and another outside interface.  I don't want to do load balancing, etc.   I simply want to use the second DSL/OUTSIDE INTF dedicated to a point to point VPN.  Then I thought I could use access-lists to permit communication with the inside, etc.  I'm new to this and I'm having some problems as of now.  Is this possible to do?

Sure, as long as it's a dedicated VPN.
Acls is definately the way to control access.
You need to setup the LAN-LAN VPN, and add route statements on the PIX:

  route <interface name> <public ip of VPN Peer> <next hop IP>
  route <interface name> <Private LAN subnet> <mask> <next hop IP>

What's at the other end, another PIX?

lrmoore:  Thanks for the quick feedback!  There is a 515 on the other end as well.  I'll work on this ASAP and post how it goes.

lrmoore:  I'm still having some problems.  I'm not sure if I'm doing the routes right.  As I said, I'm really new to this.  Here is a sample of the config.  The second interface is intf2.  It's ADDR for that interface is lets say 206.166.x.145.  The DSL router ADDR is 206.166.x.150.   The ENDPOINT ADDR for the vpn i want to establish a direct/dedicated tunnel with is lets say 65.88.x.50.  The inside subnet for that location is 192.168.x.x.

Managing Security Policy in a Changing Environment

The enterprise network environment is evolving rapidly as companies extend their physical data centers to embrace cloud computing and software-defined networking. This new reality means that the challenge of managing the security policy is much more dynamic and complex.

I think you just need to add a route statement:

   route intf2 65.88.x.50  206.166.x.150

lrmoore:  Cool.  I'll add the access list statements, then try establishing the tunnel.  I'll post follow up information asap.

lrmoore:  Sorry for the delayed response.   The interfaces at site A and site B are able to communicate now.  I'm having some problems getting the tunnel established, but I'm sure there is something that I'm over looking.  I'll keep pounding it out.  I'll go ahead and close this one out.  Thanks much for your assistance.
