I have 5 sites across the globe that access their 'local' networks using a Cisco VPN. We also have a hosted web service (off core network) so we have to use a hosts file (with external address of web server) when users attempt to connect to both their local office (via VPN) and web server at the same time.
The web server will soon be moving to our head office which is ok for users based at the head office (dispels the need for a host file as DNS will work), but those visitors to head office from abroad will not be able to access the web server since their host files sends them to the external address and NOT the internal address.
I guess that one to one NAT is the answer - but HOW??
Thanks muchly any assistance provided...
