Hello!
First sorry about my english.
I configured remote access ipsec, without split tunnel on a 2610 router. Everything work fine, the clients can reach the inside network, but sometimes
when i try to reach for example google.com, nothing. I start to ping -t google.com, nothing, but suddenly the client start receiving ping and later nothing again. Maybe PAT ?
My config:
aaa authentication login default local
aaa authentication login VPN_CLIENT_LOGIN local
aaa authentication ppp default local
aaa authorization network default local
aaa authorization network VPN_CLIENT_GROUP local
!
crypto isakmp policy 10
encr 3des

Any idea? Thanks
