Ultra VNC problem connecting between offices

[Stinky]

trying to connect to our office 30 mile away. using ultra VNC.

i've called them up to make sure they are runing the server. still nothing connecting. not even asking me for passwords.
any ideas at all.

i have got the local machine + the internet ip and port to try. but nothing.

any ideas?
