Hi, We have an issue where by we connect to various customers and the Cisco IPSEC remote access works fine from our LAN through an ASA5505 to a customer site.
We have 1 customer that we have some issues with. We can connect from the LAN through to the customers VPN, authenticate and establish a tunnel but in we cannot pass traffic. When we try from outside of the office on a public internet connection the VPN works fine. ANy ideas what could cause this issue?
Another possibility is that, since you say that this remote access connection works fine for other customers, it is possible that your local LAN subnet is the same as the remote end LAN Subnet, for example if your LAN is 10.1.1.0/24, and the remote LAN is the same, when you connect via VPN Client, when you attempt to access resources on the remote LAN, your local machine thinks you are trying to access resources on your local subnet, so it never makes it over the RA VPN tunnel. This would explain it working from a public Internet connection, but not within your office.
