19.7 Legacy Series / Re: Use DNS servers just from one uplink or add priority
« on: July 31, 2019, 12:31:26 pm »
I'm in the same boat now.
Telekom switched us from ISDN to SIP-Trunk last Monday.
Fons are dead since then
DSL connection works, I have internet access.
Problem is DNS resolution of Telekom's Outbound Proxy and SIP Registrar.
reg.sip-trunk.telekom.de and sip-trunk.telekom.de are unknown.
I let the PPP override the OPNsense DNS-Servers on login.
"Allow DNS server list to be overridden by DHCP/PPP on WAN"
That doesn't help. Even with no DNS-Server configured in OPNsense internet access works but it cannot resolve the two SIP related hosts. So OPNsense seems to have received a DNS-Server on PPP connect.
Does anyone have a "working" DNS server address for this setup?
Regards
Stefan
