i have a ASA 5505.
when clients connect using anyconnect VPN they loose connection to the internet. DNS resolve seems fine.
In the log of the ASA i receive these errors:
Group <GroupPolicy_VPN> User <administrator> IP <PUBLIC IP ADDRESS> Transmitting large packet 1250 (threshold 1206).
Anyone have any ideas?
My config looks like this:
ciscoasa(config)# show run
