This is definitely a non standard setup. I was hoping to avoid a landline over fibre, however, my SO is insisting that we keep the landline, even though she hasn't noticed it's been disconnected for about a month.
I've recently had fibre installed, and because I run a number of services on my linux server from home that the family accesses both inside and outside the LAN, I needed hairpin NAT. The standard vodafone fibre modem/router doesn't do hairpin NAT, so I got a mikrotik router to act as a bridge (adding the necessary VLAN tag) to a router I already had that did do hairpin NAT, which acts as the gateway to my LAN. Everything was good.
However, now I need to add in a landline. So the question is, if I attach the vodafone supplied router to my LAN - turn off DHCP (server) etc, will it (effectively) act as a bridge from the phone to the relevant vodafone SIP server on the outside?
Anyone had any experience with this?
Cheers
