Follow-up on Sametime, tunneling and two NIC’s


Tags :


I originally posted this on March 17th, and got the first part working successfully.  Clients on the outside are easily able to connect either tunneling or direct depending on their ability from the outside.  Unfortunately there was another catch were weren't so bright about.  If you happen to use the Sametime server in tunneling mode and NAT (Network Address Translation) to the outside world, and then for good measure decide to toss a second NIC card into the mix, well lots of things can break.

  • If you leave the second NIC enabled then it will start trying to grab that NIC as the bind and tunneling and whiteboarding starts to fail
  • If you disable the second NIC and run enterprise backups across it (as most companies will), then you screw yourself there
  • If you move a NIC out of the NAT into a DMZ or other area, you expose the server
  • If you chant loudly "Sametime rules the planet and LCS is a spawn of Satan" nothing happens but you feel better about your decision to use Sametime

Ok, I am kidding about the third, I mean last one.  Needless to say I need everything to work together.  Backups, two NIC's and Sametime with tunneling.  By the way, yes Lotus pushed out a technote under #1088421  Link
