How to open port 3101 on my server running on SBS

[Aienstaien]

I have server setup on Microsoft Small Business Server, but to make connections with the other system I need to secure as port and it ask for 3101 number at its port, but when I try to connect it, it does not allow to do so. Please let me know how do I open the Port 3101.

1st off all, you only need an outgoing connection on 3101, not inbound which frankly is possible on a NAT router, Port 3101 must be configured for an open bi-directional traffic. It's not rocket science it does not open the network to attacks, there's no gigantic security risk.

Aside from port 3101, users can also initiate the same inbound/outbound traffic through port 3500 for messaging and PIM exchange when port 3101 is blocked or incompatible with the platform utilized by the user. you don't have ISA 2000 installed, just SBS2000 with Exchange, theres nothing blocking ports. SBS2000 without ISA 2000 is a naked system. Plug it in to the Internet and you are vunderable to exploit.

You can enable TCP/IP packet filtering on the NIC that is installed on the computer with SBS2000. You can enable packet filtering on a NIC in virtually all Windows O/S product line. Port 3101 is also used by other software to connect to a Blackberry Enterprise server, such as Lotus Domino, Microsoft Exchange, and Novell GroupWise. Packet filtering on the NIC is off by default.
