Hi,
We use PIX 506E and VPN Client 401
our vpn users can access internal machines
but they can not access internet
ping to internal hosts works but they can not ping anything outside.

is this because of the NAT disbaled for VPN pool
or the permitions?

regards
xdeq

I found the problem:

had to change
access-list inside_outbound_nat0_acl permit ip any 172.17.2.0 255.255.255.0
to
access-list inside_outbound_nat0_acl permit ip 200.200.200.0 255.255.255.0 172.17.2.0 255.255.255.0
access-list inside_outbound_nat0_acl permit ip 200.200.201.0 255.255.255.0 172.17.2.0 255.255.255.0

and added this line:
vpngroup csigroup split-tunnel inside_outbound_nat0_acl
 
I have not ben able to get pptp vpn's to surf the net


but for the IPSec client

add this

access-list split permit ip 200.200.200.0 255.255.255.0 172.17.2.0 255.255.255.0

vpngroup tmpgroup split-tunnel split

(note*)



*you have
access-list inside_outbound_nat0_acl permit ip any 172.17.2.0 255.255.255.0

for your VPN NATING ACL i would remove "any" and add the subnet address

access-list inside_outbound_nat0_acl permit ip 200.200.200.0 255.255.255.0 172.17.2.0 255.255.255.0
access-list inside_outbound_nat0_acl permit ip 200.200.201.0 255.255.255.0 172.17.2.0 255.255.255.0
(if you have more subnets)

 
also i've been told by TAC not to use the same nat0 acl statment for the xlate and the spliting. Create another one the same as the nat0 and call it split as stated in my above post and use

vpngroup VPNGROUPNAME split-tunnel split
