Adding an additional route to a PIX 525?

    I have a PIX 525 ( that serves as the default gateway
    for a bunch of client machines. I also have a site-to-site VPN
    connected for access to a remote office, it's local IP is and the remote end is

    What I would like to do is be able to add a static route on the PIX
    525 to say that all traffic destined for should be
    routed out via I used this command on the PIX:

    route inside

    But, unfortunately, it didn't have the result that I wanted. It was
    successful in so far as it let the PIX 525 ping the PIX at the remote
    VPN, but it wasn't forwarding client requests for that had
    their default gateway set to (i.e. the 525). What am I
    missing here?

  2. I believe we are in the same boat, or at least rowing next to each other.

    I think that as someone replied to my message, you also need to add the
    remote networks to the proper ACLs (Inbound/Outbound NAT, & Crypto ACLs) to
    allow it to pass traffic to/from the remote network. You have to be sure
    that the traffic is not NATed on either end too.

    I'm pretty sure I have all of that in, though I'm missing something. I'm
    going one step further and have another subnet beyond the remote VPN subnet.

    You can't do this on the Pix. You can't bounce packets off the inside
    interface and route them back inside the network to another host. I'm sure
    that Walter is sick of telling people this ;-)

    What you have to do is to define with ACL which traffic goes to the VPN
    (should be encrypted). PIX can't route packets throught the same port, so I
    presume that your VPN connection is made on your outside port.

    As I've said earlier, check, you have a lot of cookbooks regarding
    this specific sceanario.

    What he is trying to do is have the Pix as the default gateway on but then have that route traffic destined for the remote
    network back inside to a different gateway, 172.16.188 (doesn't say what
    that is). The pix won't 'route on a stick'.

    Is another name for this a "hairpin" connection? It seems unfortunate
    that I can't get this accomplished... :-( having to add 10 static
    routes to 100 client machines is a lot more work than adding one
    static route on a PIX!
