Hi, I have a network behind a firewall that from which I would like to enable some of my clients to use some internet phone devices like yapgear and infoacel card. My firewall is on my gateway which is on RHlinux machine -implemented with ipchains for NAT. I was told putting my clients on a public IP will solve my problem , i.e outside my firewall. This I don't want to considering the security risk; hence I am planing to try port forwarding with ipchains to see if I can get around this. Has anybody done this before, I am not too familier with VOIP either, how can I find out what port to use ? Thanks for all help rendered in advance.
