Hi everyone, I'm looking for some help on how to get a IConnectHere, a PC-to-Phone service, to work through a linux masquerading firewall. I've got a home network that gets its internet connections from a RedHat box running an ipchains packet filter that has masquerading turned on. I'd like to be able to use my windows box (behind the firewall) to access IConnectHere's internet PC-to-Phone service. However, I haven't had much luck. The web page help isn't terribly helpful. All they say is which ports have to be opened in the firewall: For out-going and in-coming traffic the ports are: TCP UDP 12053 12080 12083 12120 12084 12122 12200 12180 12202 24150-24250 12122 12110 However, it doesn't say whether this is a 1-to-1 mapping, or whether these ports need to access my entire unpriviliged port range, etc... Additionally, it does not say which ports (UDP in particular) must be explicitly forwarded to the windows box. This is vital because without it, I can't correctly route the incoming UDP packets carrying the voice of the person who I'm trying to talk with. I've been able to get Dialpad.com to work through my masquerading firewall by using the ipmasqadm utility, so I know that this sort of thing can be done. Has anybody else tried this with IConnectHere? I've got several emails out to their tech support right now, but haven't heard anything back yet. Any advice would be greatly appreciated.
