I think you need this:

nat (inside) 0 access-list nonat

access-list split permit ip 192.168.1.0 255.255.255.254 any

vpngroup sec split-tunnel split

hello,

actually i already have nat (inside) 0 access-list nonat

i only forgot to paste in the post, secondly i tried with

access-list split permit ip 192.168.1.0 255.255.255.254 any

vpngroup sec split-tunnel split

but no luck, still the same.

What's this route for? That would include your vpn pool.

route inside 192.168.1.0 255.255.255.0 172.20.4.1 1

and shouldnt the split acl be

access-list split permit ip 172.20.0.0 255.255.0.0 192.168.1.0 255.255.255.0

the route is for the pix to know that it's local to it. actually it did'nt worked so i removed it

and yes the split is as what are have written but still no luck..

access-list split-vpn permit ip 172.20.0.0 255.255.0.0 192.168.1.0 255.255.255.0

i cannot understand the connection works fine and even on pix i see tunnel is created and both phases are completed in syslog .. still i can't access anything inside once connected must be something i am missing.

any help would be really apperciated

Your vpn client pool name does not match what you have in your vpngroup

ip local pool vpnclient 192.168.1.1-192.168.1.2

vpngroup sec address-pool isnetvpn

should be....

ip local pool isnetvpn 192.168.1.1-192.168.1.2

vpngroup sec address-pool isnetvpn

these are not correct...the source is wrong, should be your inside network which you would like to cross the tunnel.

access-list nonat permit ip 1.2.3.4255.255.0.0 192.168.1.0 255.255.255.0

access-list split-vpn permit ip 1.2.3.4255.255.0.0 192.168.1.0 255.255.255.0
