PIX 515 VPN and 2620 internal routing

[kees7]

We have a Cisco PIX 515 with IPSEC VPN between our LAN and the internet. In our LAN we have a 2620 Cisco router which connect our LAN with our other offices. In our LAN the default gateway is the 2620 router. The default gateway on the 2620 is the PIX 515. When we make a VPN connection, client or pix-2-pix, I can access our LAN but I can't access the other offices. How can I give the VPN client or the other pix access to the other offices. Please help.

You'll need to add static routes to the Cisco Pix for each of the networks located behind the router with the Cisco 2600 router as the next hop to reach those subnets. You'll need to add acl entries to the match list for VPN traffic to include traffic from VPN clients to these networks. If the Cisco 2600 router is the default router for these remote lan's, then you won't need to add a static route (on the router) for the VPN pool subnet pointing to the Pix as the next hop because the default route in the Cisco 2600 router will suffice.

I've the following config in my pix515. I have two problems. The first is that the inside users can't connect to the internet (most of the time, very strange) and our mail server can't connect to the internet( this has started since I added the VPN lines). When I remove them everything is working fine. Second, when I make a vpn connection I can only access our inside 92.0.0.0 network and not the networks (93.0.0.0 etc..)who are connected through the 2620 router. The default gateway is the 2620 in our network. The default gateway on the 2620 is the PIX 515. Please help.

mail server ip = 92.0.0.6
mail proxy server ip on dmz = 192.168.52.2
surfbox server ip = 92.0.0.44
2620 ip = 92.0.0.254
