FWA710 unreachable from the intranet

Luca_G · February 14

Sometimes (every 2 weeks) the modem becomes unreachable from the home network. It happened today, February 14th, around 5 PM. I can't browse the internet and I can't reach FWA710 (192.168.1.1). It seems to be related to 5G network issues (changing BTS) that then propagate to the internal network (Passthrough IP). The only way to resolve this is to reboot by unplugging the power or rebooting from the Nebula app. What could it be? (I've a Fritz 7590AX)

yes it because of this please vote on it

Feature Request: Immediate DHCP Renewal for IP Passthrough Mode — Zyxel Community

the way in which IP Passthrough works is like a NAT 1:1 where the WAN interface is independent of the LAN but the IP are the same to device and really all thats need is the LAN DHCP server to have a low lease time if there is a IP change on the WAN side.

OK but why I can't do anymore to reach my FWA710? (192.168.1.1)

Its because the router WAN IP not FWA710 but your connected router IP its on is wrong when the WAN IP of the FWA710 changes.

The FWA710 (which likely is the same as my FWA510) LAN lease time is 1 hour when in IP Passthrough so you may have to wait that long till your connected router gets to correct new IP

Mhhhhh that's not good. I seems it's better not to use Passthrough to solve the problem. Am I right? Or there is another configuration to apply to solve the problem?

Thank you very much!

Its down to Zyxel to make this work better there is a way there just have to do it but I'm starting to think it will not happen.

So yes not using not using Passthrough would likely solve this.
