Hello I have a cable connection of Unitymedia and have a Fritz box 6490 in the bridge mode running (over LAN 1 everything works, but double NAT etc., therefore the bridge mode).
On Bridge-Port LAN 2 I have the Sophos UTM 9.5 running.
Unfortunately, I can not reach any pages / services via IPv4. IPv6 works fine.
If I attach a FritzBox instead of Sophos it works. But you also had to make the following setting.
How can I adjust that in the Sophos that I can determine over DHCPv6 the AFTR address?
