Okay this happens to be the weirdest thing I've seen. Here is the setup. I have a Pix 515e firewall. I have VPN setup on it so my users can connect remotely from across the country.
I have one set of users who can't connect. Let me clarify. The VPN client connects, they are given a IP by the firewall, but they can't send traffic over the tunnel. I've tried pinging everything from the inside interface of the firewall to servers behind it and nothing. Now the set of users that aren't working all exist in the same location, running on the same network, and behind their own firewall. And they were working up until a week ago. Their provider says he hasn't changed anything on his firewall and I know I haven't changed anything on mine. So any help would be greatly appreciated.
Without even doing any sniffing I see that packets are being bypassed for some reason. Everything appears right. I've reinstalled the VPN client software, redid the connection entry, and still nothing.
Again and whats weird is that other VPN clients are working. Just not any from this particular location. Is there anything in particular I should be looking for when I ask the IT department that controls the firewall on this location. (And it was working a few weeks ago).
