I have a LAN to LAN VPN session set up between myself and another company. It is working fine. However, I do have one quesiton.
Is is possible to limit what the other company sees to a single IP addrress? I have the single IP set up in my VPN, but I don't know if it is actually limiting the other company or if they have access to the whole subnet.
Ok, I see what you mean about the ACL, but still a little fuzzy.
The LAN to LAN is set up between two 3000 series concentrators only, there is no PIX involved.
The only ACL I see on the VPN admin page is to limit access to the admin functions of the box.
Within the VPN administration web page, under LAN to LAN connecitons, on MY local network I have an IP of 172.16.219.5 listed. Does this limt the other company to JUST that IP, or are they opened up to all of the 219 network?
