We've got several remote locations with PIX 501s. I want to be able to access with the desktop client (on XP Pro) from anywhere. Problem occurs when I'm on behind another PIX- authentication seems to work fine, the gold lock icon locks and I get an ip address on the remote LAN. However, I can't ping or access resources on either the remote or the local LAN. When I'm not behind a PIX, everything works fine. I've got "sysopt connection permit-ipsec" & "isakmp nat-traversal" enabled.
I have this problem too.
