Evaluating OPNsense for replacing a untangle firewall
Has anyone done this before?
In simple terms the setup will be
WAN 1 Comcast business Cable Static IP WAN 2 T-Mobile business gateway with Static IP
LAN 1 192.168.x.x with IP phones and a FreePBX appliance server, SIP trunking from ClearlyIP.
End goal is a firewall that will use Comcast 100% of the time until failure, then switch to T-Mobile until restored for a period of time
Currently the untangle box is running with just the Comcast gateway enabled, When T-Mobile gateway is enabled I lose voice traffic due to dynamic routes do not properly handle the 2 gateways.
Comcast alone works, T-Mobile works alone so can OPNsense properly handle the routes when they change?
PBX can stay down for a few minutes during the switchover times, but must come back with correct routing for port 5060 traffic.
Thanks
