Sorry to do this to those who have been helping out and are borred with port related questions, but....
I have installed a voice-over-net software package on my SME 5.6 server, (it's a sever for my home network, hence not too worried about it), it requires access through UDP port. Which port it doesn't matter as I can change that.
I problem is in this, no-one from out side of my home network can gain access through any UDP port.
I have 2 ethernet cards, eth0 is connected to a cable modem and eth1 is connnected to my hub. The server is set to a sever/gateway setting. My understanig of the security settings is that it allows all UDP port access from my network (eth1), but none from the internet (eth0).
I have tried to append the IPtables, with no luck (it kept telling me that multiple " -s " commands are not allowed).
I have installed the Port forwarding rrp, but as I dont want to forward the packets to another machine, I don't see how that can help me.
Please explain to a relative nOOb to Linux (my background is in web page design and only recently I have began to learn Linux)
Thanks for any advice
Matt
