Solved: Once connected to remote site VPN users can't go anywhere

UCcomp2007 · ‎06-30-2009

We have setup a remote site IPSEC vpn on Cisco ASA 5520's. When users connect via AT&T Air-cards, they are able to connect to VPN and get to internal servers and the internet (no split tunneling being used). When users are on local area network at home (behind wireless access points, firewalls) or in the office on LAN they can connect, but can't go anywhere (can't ping any internal server or internet).

We have verified that their is no private addressing conflict.

Does anyone have an idea of what could be causing this?

Thanks in advance,

Try enabling NAT-T on asa, have them try after you enable it.

PIX/ASA 7.1 and earlier

pix(config)#isakmp nat-traversal 20

PIX/ASA 7.2(1) and later

securityappliance(config)#crypto isakmp nat-traversal 20
