Split-tunnelling not working right - no Internet access with Cisco Vpn client
I can not browse the Internet when connected to my Pix 501 with the Cisco Vpn Client. So I rechecked my split-tunnelling configuration, but cannot see what is wrong. I've compared to many split-tunnelling suggestions in this forum but can not see where is my error. Can anyone see what I'm missing ? (everything else works ok)
What is normally the proper Acl format to use for split-tunnelling, assuming 10.200.6.0 is my internal ip network, 10.10.8.0 is the Vpn ip network:
1) access-list split permit ip 10.200.6.0 255.255.255.0 10.10.8.0 255.255.255.0
2) access-list split permit ip 10.200.6.0 255.255.255.0 any
Most of the configs I saw were using one of these two. Any one better than the other ?
If I define 2 vpngroups, should I create 2 Acl's (identical) to use for each vpngroup ?
So here is my configuration :

Yes, I've seen various issues with older versions of the client software. That's why Cisco releases so many versions of the client...they're always having to fix bugs! In their defense, however, they do add features as well with those newer releases.

When I do ipconfig/all, I noticed there is no gateway ip address for the vpn connection. Is this normal ? Should'nt there be one ?
Yes, that's normal.
ASKER
I didn't see the "crypto map mymap client authentication LOCAL" in the Cisco sample Vpn config file. I connect to 2 other Pix using Vpn and they don't have that command either.
2. Oh Oh - can not ping the Dns server 10.200.6.5 when connected in Vpn.
I just tried another Vpn client (4.8.02.0010) from another laptop and I'm able to browse the Internet. Would there be a problem with an earlier version of the Vpn client (4.6xx) ??
