outside users connect using vpn client ver:4.6.03 to a pix515e successfully. They can access our subnet of 172.16.0.0 with no issues. However when trying to access anything on one of our other networks (VLANS) or point to point t1 lans, they cannot. Our router is a 3845 that is the gateway between these lans.
I am not sure if this is an issue at our 3845 or our PIX. Any help would be appreciated. Thank you in advance.
Can you please make sure that you have the nat configured properly.
Are you doing split tunneling?
If so, make sure your split tunneling ACL does have the networks for the VPN client pool.
