Yes, I understood it right. That is the way to do it. I just assumed the SIP PBX inside is Asterisk-based as well. If not, maybe there is another way like my trick with "externaddr=xx.xx.xx.xx:5062". I did this with 3 separate AstLinux PBXs behind one single PFSense firewall on the edge. > -----Original Message----- > From: Michael Keuter <li...@mksolutions.info> > Reply-To: AstLinux List <astlinux-users@lists.sourceforge.net> > Date: Tuesday, 5 September 2017 at 6:20 pm > To: AstLinux List <astlinux-users@lists.sourceforge.net> > Subject: Re: [Astlinux-users] Guidance on configuring NAT on Astlinux > > >> Am 05.09.2017 um 09:16 schrieb Michael Knill >> <michael.kn...@ipcsolutions.com.au>: >> >> Hi group >> >> I have a bit of a tricky one that I want to run past the Astlinux firewall >> experts. >> >> Scenario: >> An existing PBX (soon to be replaced) using an existing SIP Provider sitting >> BEHIND an Astlinux appliance which is connected to another SIP Provider. >> >> Should I just be able to do NAT EXT -> LAN to the internal PBX for 5060 & >> Media Ports using the Source IP Addresses of their current provider?
