PIX 515E v7.1 L2L PIX 501 v6.3

Greetings all,

I need some help with the following scenario. Site A is 192.168.100.x network with all computer default gateway pointed to the inside of the PIX 515E (192.168.100.1). Site B is 192.168.101.x network with all computer points to the inside interface of the PIX 501. Is it possible to make Site A PIX 515E configure site to site VPN with site B Cico 501 while at the same time allowing Cisco VPN client connecting to site A Pix 515E?

What about intersite routing? For example, computer in site A can access computer in site B? I know PIX does not do routing? Do you have a sample configurations that I could view or point to the right direction.

Thank you in advance!

Of course a PIX can do routing, it is at heart a router with enhanced security features. But it does not run IOS and supports only static routes, RIP and OSPF, and they're limited.

Off the top of my head I think you be needing something along the lines of:

Re: PIX 515E v7.1 L2L PIX 501 v6.3

Thanks Grant. I've seen people posted on different sites saying that the PIX can't do routing. In this case, all internall traffic that go to the internet would be just route inside 0.0.0.0 0.0.0.0 outside interface.
