[jpandhobbes]

I have the VPN working and have split-tunneling enabled but can't access the LAN behind the PIX 501. Below is copy of config.

Maybe this has been sorted out already, but here's my 2 cents on the matter.
You need to add to you NONAT statement: access-list inside_outbound_nat0_acl permit ip any 192.168.1.128 255.255.255.192 to disable NAT between inside network and your VPN network.

eg:
access-list NoNat permit ip [inside network] [vpn/dmz network]

This should help you solve your problem.

Notben:
I highly recommend that you edit your access-list 101 to specify a bit more what you want to be done here.
access-list 101 permit ip any any is too general and basically tells your pix NOT to use NAT at all.
nat (inside) 0 access-list 101 is basically used to disable NAT between your interfaces (eg. between your inside and dmz/vpn interfaces)
Your PIX already knows what network lies on each interface, so using nat between your "internal" interfaces will only confuse it.

And before I forget. Adding icmp permit any unreachable outside seems to help solving icmp problems. Haven't managed to see the logic behind this yet

Cheers

To reply to the march 5th reply at 10:40 the issue(s) that where causing me to not be able to connect to the laptop were caused by either norton internet security or cisco vpn to resolve I uninstalled both of these programs

 

[jpandhobbes]

another add on note to allow the ping and remote desktop without uninstalling cisco vpn you can just change the service for cisco to manual. I did this after reinstalling cisco and then i was able to ping the laptop if the service was not running.
