Site to Site VPN Issues

So we have a pair of CIsco 1812 Routers doing a site to site vpn over the internet with each other

Things like Exchange, file transfer, dns, logins, etc.. all work over this connection, but RDP will not work

It doesnt even start to connect, just times out like it is being blocked

I have disabled the firewall on the RDP server, but doesnt work

Read something about setting the MTU size on the connection, but didnt work either

The connection does work on a client to site vpn and locally no problems, but over the site to site connection it wont

Any ideas or suggestion about what to try?

Re: Site to Site VPN Issues

So just for an update, we removed our port forwards from the head office router and it all worked after that

Has anyway got an idea why port forwards would affect it in this way?
