Hi, I've moved my retrospect server (WinNT) behind a firewall, but some of my clients are still in the unprotected wasteland needing backup. To limit the holes I put in my firewall to allow this, I need some details about retrospect's port/protocol usage. The manual says that retrospect uses port 497 with both tcp and udp. When does it use tcp, and when does it use udp? If I simply put a tcp hole in my firewall at port 497, I can see clients only if I use direct addressing (backup works this way as well). When I tried using multicast or subnet broadcast (with 2 subnets listed: the one the clients are in and the local subnet behind the firewall), to find clients, I never get anything to show up. I've tried putting in a udp hole (port 497) hole in the firewall, but nothing changes. My guess is that my setup is blocking something retrospect is trying to do, but without some more info on how retrospect tries to talk to clients, I can fix it. Any info/pointers to relevant docs would be greatly appreciated. Cheers, -Andy -- ****************************************************************************** Dr. Andrew R.
