Hello,

I tried this however on the LAN rule outbound it will only allow a Gateway for an Inbound request not outbound - any ideas?

Hello,

It's both IAX and SIP (IAX inter Office) and SIP for the main lines - without the forwards we end up with one way Audio.

I'll look at the setting you mention :-)

Sorry about confusion dealing with a 100 things at once you know how it is!

Bump on this.

SIP provider says they can't lower the keep alive and was fine on the other firewall - I just prefer OPNSense. Is there away of disabling State Tracking on Port Forwards?

Thanks
Peter.

Thanks will take a look - strangely didn't have this issue with PFSense - will look into the trunks. Is there anything that can be done on the firewall side?

Hello,

Have a NAT rule working perfectly well for an inbound IAX / SIP trunk however it's seems to drop the trunk randomly and the only way to get it back up again is to reset the states on OPNSense to bring the trunk backup.

Any ideas?

Hello,

Looking to setup gateway fail over - did it on PFSense via static routes to the next hop however want to set it up properly. Have a backup LTE connection however have a SIP trunk that has to go out the fix broadband line - this is has a manual NAT setup to mask the traffic. Basically want to pass all traffic other than that over the LTE when the gateway is experiencing packet loss (currently have a flapping line) however still route the VOIP via the WAN.

Any suggestions?
