I would recommend you not try running this throught the firewall per se, but instead consider a tunneled connection of some sort between the two sites. Once you establish the tunnel, the WINS resolution and updates can flow over it without any special preparation. Without it, you'll have quite a job to allow only the specific kind of traffic you wish through. Lots of MS stuff you don't want from the outside use the same ports. FWIW we've had good luck with PPTP which is native in NT4. Lots of conversations way back when on this list about why this is not (completely/very/any) safe, but there are other such products including one from TIS that offer different degrees of safety and cost. >-----Original Message----- >From: AC [SMTP:ac0at_private] >Sent: Tuesday, March 31, 1998 8:45 PM >To: firewall-wizardsat_private >Subject: TIS Gauntlet : WINS and Exchange > >Hey folks, > >So I am currently on a project that involves >a number of m$ products; <sigh> >"Know thy enemy" is what I always say >though. > >check this: the company has 2 WINS servers, the primary >one is in their uptown location.
