I have a very general question I am looking to get input on.  Not sure there is one solution to the problem, but am looking for input from the experts.

I have a remote site with two users.  This site has a DSL connection to the internet.  The site has a single static public IP and the carriers modem is handeling the firewall and NAT operations. Each of the computers has VPN client software that connects back to our central office.

The VPN clients drop connection consistantly.  

This is the same VPN client setup I have used numerous times in different locations.  The only difference here is that at the other sites there is normally one user behind a public IP.  In this case there are now multiples.

My question is, would this cause a problem for the clients of a single public IP has requested mutliple VPN terminations?  I am thinking once the connection makes it back to the remote site and passes the carriers routers NAT translation it may lose something when passing packets to the end host.

True?  Not True?   Am I TOTALLY off base and should go back and relearn networking basics?

Thanks for any input
