I would like to create a site to site vpn between 2 location, lets call them Site A and Site B. I set up on Site A an inside (ethernet 1) and logical (also on ethernet 1) interfaces. Site B has only an inside zone. Each office has a PIX 515 with version 6.3(4) running on it. I am able to create tunnels so that inside A can access inside B (but I need that logical interface of Site A could access inside B and vice versa) . I was trying also to establish tunnel between DMZ of Site A (ethernet
2 interface) and inside - but I am unable to create the funtionality that I need. The following is what I would like to do.
VPN conectivity:
Logical interface (ethernet 1) of Site A can access inside of Site B Inside of Site B can access logical interface (ethernet 1) of Site A
- OR - if above impossible
DMZ (ethernet 1) of Site A can access inside of Site B Inside of Site B can access DMZ of Site A
Do I need any switch to do that with logical intf (it's vlan on pix of course). I have Netgear FSM726 - and I tried to filter this traffic but it doesn't work.
My Config:

Basically, I can connect from inside (Site A - 10.1.1.0) to inside (Site B - 192.168.73.0) and ping any host (of course if I set up tunneling between inside interfaces). But, what is the most important for me (above config) I cannot ping host from 193.168.73.0 (Site B) in
193.2.2.0 (Site A). Even I cannot ping from any internal host/193.2.2.0 logical interface 193.2.2.1 on SiteA, but I can ping inside interface
10.1.1.1 from any host/10.1.1.0 - why? I have checked all the cisco web site examples, I cannot find a single example where they do something like that. Does anyone have an idea how to configure this also that switch if important - or run it on interface 2 (DMZ)?
Thanks very much in advance.
