VOIP Fritzbox behind Sohos XG

mario Andrick over 7 years ago

Hello,

last time I got many problems with VOIP. Sometime it works great and another day it won't work.

Does someone get some experiances between SIP an VOIP with an Fritzbox 7490 ?

My Firewall rule is shown below.

The content of SIP Fritz is:

Or should I try it with an Portforwarding Rule ?

But i there a difference between a portforwarding and a "Network Rule" ?

Thanks 4 your help

Hello,

after testing a lot ports the follwing rule seems to work:

And the Option NAT & Routing "Rewrite source adress Masquerading" should be disabled.

By this way, maybe someone could explain me action of this NAT rule ?

Thanks a lot

Mario,

On dnat when the rewrite source address is enabled, the origin ip will be masqueraded to XG Ip and your destination LAN up will se the request coming from XG.

The ports you opened are ports needed by the fritz box, I guess.
