we have a dialup server and a dns server, two different machines. Our mail server is running within the dns server.
We have a dial-up client who wants to have mail server running in their office. and an 8 workstations to beconnected to the internet.
No problem with connecting with the internet. we have setup a proxie server on their side using a modem. The main problem is their server is not visible to the internet world. we cannot ping it from our side. we provided a valid IP on their server and sendmail is not functioning well.
PLEASE HELP WE REALLY DONT KNOW WHAT TO DO.
