i have a problem with the vpn sessions,the users connect to internet with GPRS cards (wireless link) they are using the cisco vpn client 4.6.00 the problem is when in the configuration of the client check the option ipsec over tcp (see image) then the connection
drops every 10 or 15 minutes the pc have windows xp and are connecting to a cvpn 3005.
if i connect to internet with adsl, dial up, etc. there is no problem
but if i uncheck the ipsec over tcp and check ipsec over udp the connection works fine
