What ports to open to allow oubound VPN auth. 1

[Digole]

My company is conducting an audit. The audit agents need to work temporarily from our office and they need to authenticate to their home office via VPN. They are using Check Point VPN-1 SecuRemote clients Ver 4.1.

I'm totally unfamiliar with this product, and I am in need of assistance. What ports do I need to punch on our firewall to allow these agents to communicate with their home office?

The helpdesk of the company who the audit agents work for are clueless, and the agents themselves are just bean-counters who are barely computer conpetent.

Anyone got any clue?

What firewall are you using? I'm investigating the same thing.

Hi..

I'm pretty sure that SecuRemote uses some weird and wonderful UDP ports for authentication-although I'm not sure exactly which ones. However I do know that we had big problems getting SecuRemote working at all when it was behind another firewall that was doing address translation-In fact we couldn't get it to work at all!!

Anyway-I think you may find some useful info on

There's a lot of FAQ on there which may be of assistance!

Try letting these ports out:
TCP Port 256: earlier versions os securemote
TCP Port 259: client auth via telnet
TCP Port 264: used securemote later versions
UDP Port 500: for IP sec
Good Luck! and let us know if you resolved the issue!
