problem connecting to po3 server

[cpai]

Can any one tell me why My Office communicator and VPN is not working behind a NAT router.

A subnet of a subnet which is routable IP is used for NAT overload . Internet and E-mail are working , but VPN and office communicator is not working.

I will get the Internet from Corporate and POP server is also located in the Corporate network.

Please give me a solution for it.

Thanks,

is it a one to one nat?
your overload works but are you mappnig the required ports to your host machine properly for the vpn tunnel?

Thanks for your reply.

It is not one to one. One to many. Bu I don't know how to Map the required ports for VPN.
The Natted Ip's are Dynamically allocating to different worksattions. How Do I do mapping? Please guide me in this regard.


Thanks
