  • gre behind pix\netscreen

    here is the scenario I have a main site with cable internet going to a pix 515e running 6.3 ios from there the connection goes to a 1721 cisco router. the inside network is connected to the 1721, and the 1721 also has a T1 that goes to another building down the street with another 1721. now as a backup I am wanting to use another cable connection at the remote site. this connection would be behind a netscreen 5gt. now what i am trying to do is get some sort of tunnel between the main site and the remote site to use as a backup in case the T1 goes down. what I am trying to do is create a simple gre tunnel between the two 1721's but it does not seem to be working between the two firewalls and i am just looking for any advise as to why this may be . currently i have no extra public ip's to give so at both sites i am trying to simply foreward gre to the routers maybe that is the problem i do not know. agian any advise would be helpful.

    Can you sniff and see any traffic going through or being blocked by the firewalls? Anything showing in there logs either?

    From your text I see this (just for clarification)

      yes AndyJG247 that is the diagram it seams that just a plain ipsec between the two site would be easier but i can no get it to work. I will try with wireshark and see what comes of it though.
