I'm connectig using a vpn connection and succesfully ,check out the sample config below.
For example my VPN client would like to access to the LAN internal server 10.1.1.156
What setting shuld be done as the local IP pool addresses are different subnet and do i need
to do additional routing?Any advise

I was wondering how the client is going to communicate with internal server for example which have IP address of 10.1.1.156,since the IP local pool is under 10.1.2.0 segment.Do we need to put in any routing command.

Yes, you have to add a static route on your server.
like
route add 10.1.2.0 mask 255.255.255.0 10.1.1.1
BTW, after the vpn connection established, vpnclient get a IP address(ex:10.1.2.1).
Because the vpn connection was terminated on the outside interface.
PIX treat 10.1.2.1 as a IP address from outside. So you have to permit the traffic from 10.1.2.1 to 10.1.1.156 on the outside interface,
or use "sysopt connection permit-ipsec" command to let all ipsec traffic bypass the security control.

thks for the response.If I chose to put the comand in the router instead of the server will it work?
BTW if I assigned my local IP pool in my PIX to be the same segment with the LAN will it save the routing job.
