hello , I facing a tricky issue recently. I configured a remote access ipsec vpn (ikev1) on my new ASA (v9.8).
and then, when the VPN client connected the VPN, the client can access inside source only, not able the access the internet via the VPN. yep , I know you may think some config was wrong, but , I have same config on others ASA (9.6; 9.1), it's working fine. actually, I did compared the config and still can't figure out whats the different.....
(I guess it should NAT or routing or acl)
below it's the config (this ASA has a L2L VPN and a RA VPN)
I highlight the RA VPN part:
: Hardware: ASA5506, 4096 MB RAM, CPU Atom C2000 series 1250 MHz, 1 CPU (4 cores)
!
ASA Version 9.8(2)
