[strongSwan] road worrior IP - can it also be used by services/daemons to listen onto?

[lejeczek]

hi everyone

I've a working roadwarrior which links up to a server(not 
mine, meaning - no control over it) and I wonder - can that 
IP my roadworrior gets other things use?

 From that other(server) end, the network behind the server 
sees that IP my roadworrior gets, can ping it but, how to 
make, eg. apache etc, use and serve on that IP?
If I do nmap from server's net on my roadwarrior IP it says 
port is closed.

Is it something I can do at my end? Which would be great if 
possible.
