I am running into a complex problem which I am unable to solve at the moment and the problem is to be resolved urgently.
My scenerio is as below:
we are running ISA 2004 firewall behind which we have cisco vpn client utility. We have multiple users connecting from our office to remote cisco vpn concentrator. Now I have enabled the IPsec passthrough from my ISA 2004. The first user gets connected normally. When the second user connect to cisco vpn concentrator from client ( behind ISA) the first user gets disconnected.
To solve this problem I want to use static NAT mapping on ISA so that each user will using cisco vpn client will get an public IP mapped to his machine and hence he will get the desired vpn configuration on his desktop.
I have setup this configuration on checkpoint vpn1 edge firewall and it is working fine,
Now I want to setup this on ISA 2004, tell me how to do it ?
