VPN between same IP numbered network

Hi All,

I have a user who is now employed by two companies.

Both of which use the same IP address format.

10.0.x.x

He doesn't care about getting access to his files, he just wants his emails to work though his outlook client. (RPC over HTTP isnt an option)

I was wondering if it possible to add a persistent route to achieve this?

Local Gateway : 10.0.0.25

Local IP : 10.0.1.110

VPN gateway 10.0.0.254

VPN Exchange IP : 10.0.0.55

Thanks

Reg
