Hi,
I just got a second fritzbox.
So I installed a pfsense in betweeen fritz1 (external) and fritz2 (internal).
Unfortunately the phone line is connected to fritz1 and I have several phones on fritz2.
I can not connect fritz2 to fritz1 now - there is no error, it just does not work (the state of the sip-account is disabled). Does anyone know what firewall rules need to be enabled to make this work?
I already worked through several howtos, but no success :-(
When using other SIP-providers, there is no problem....
Best regards and thanks in advance,
Otto
