Hi,
Ive got a linux firewall with Private/Public ip address on two nics.I need clients to connect via SIP from the private network to a public Asterisk PBX.Ive tried the the configs from the wiki and have not come right.
Has anyone managed to get this working and if so please share the configs or point me in the right direction.
Thanks
MS
Can you get the simpler case working, with just a single client behind the firewall? Is your problem in getting multiple clients working, or getting one working via NAT, or getting one working through the firewall filtering, or SIP works but no audio, or what? Single or multiple public IPs? More info would have helped.
If you're talking about multiple clients hidden behind a single public IP, you should be able to do that either by configuring each client on a different port (5060/5061/5062 etc) or with 'nat keepalive' (on some phones at least).
If you have multiple public IPs available, then putting each SIP client on a different public IP solves the complications - then you just have to deal with the simple NAT case. (misidentification, without misrouting too) In this case, if you can get one phone working then you can get them all working, each with a different public IP but the same essential configuration.
By 'public asterisk pbx' do you mean a public voip service, or an asterisk server you control which is on a public IP? Because if you control both ends, you can setup a VPN.
If you specifically need help with the iptables setup, you're probably better off here:

(although I can try to answer iptables questions - boss calls me 'firewalldude' for a reason ;)
