I think I have seen this problem before not sure if it was resolved One fix might be to have the device with port 80 have another LAN IP to which you NAT to each IP and routing rule from src IP and src port 80 Or fix two might be to not use VirtualServer but 1:1 NAT rule

Is 1.1.1.3 a real WAN IP for your place holder? is not it can NAT loopback

So for some reason when setting up for console cable with right settings it was not working (text output mess) on reboot it then show it was booting by PuTTY so I know the settings are right so another 24hr before the UI becomes unstable hope the console cable stays working this time

I reboot my FLEX but the problem should happen in 24hr uptime I let you know by PM for TeamViewer check

So you can just link two switches by SFP or ethernet and that will work which would mean one switch all other ports by it are limited to 1Gb to the next switch. If you need more bandwidth between the switches you can do LAG to have like 2-4 ports or more between switches for more bandwidth based on a hash like src-ip so…

The speed problem is likely to do with the FLEX100 as its not as fast going by SPI Firewall Throughput due to how its tested. I agree with the other problem with WAN IP change you can vote here you will very likely only get one WAN IP by Cellular ISP Feature Request: Immediate DHCP Renewal for IP Passthrough Mode — Zyxel…

old models don't support TLS 1.3 Kyber which breaks Content Filtering What's New ZLD5.39 — Zyxel Community

So another use case for Email is the remote user is a long way away and you don't want to give them admin access to the FLEX they can't scan the QR code on there phone for Google Authenticator so ok their is "Can not scan the QR code?" so you send this info by Email for them to add it manually then they have to send you…

The bridge mode option has nothing to do with Cellular side of things its if you have an ISP by ethernet you plug in by WAN port to run as bridge out the LAN from what I can tell.

Are you expecting a WAN IP to the FLEX100 from your Cellular ISP? What IP do you get with IP passthrough?

Because you have more then one WAN the USG has no way of knowing to get to FWA710’s IP address 192.168.1.1 so if you make a routing rule at the top. incoming LAN destination 192.168.1.0/24 next hop WAN1 That should get you to FWA710

DDNS now works was to do with this DNS proxy is badly broken in V1.31 — Zyxel Community

Ok but something does not add up…so found the cause it was a routing rule incoming zywall next hop VLAN443 to do with another thing Ok and yes that would cause the problem but before I went to V1.31 my config was for that rule: / vrf "main" routing policy-route rule "VLAN443" / vrf "main" routing policy-route rule…

Okkkkk.....this was odd so I wanted to do a sanity with my other firmware slot which had V1.21(ABWV.0)ITS-24WK43-1022-241001089 it tested fine for the DNS proxy then updated that slot to V1.30(ABWV.1)ITS-24WK47-m6271 again no problems then I booted to the firmware slot with V1.31(ABWV.0) and NOW IT WORKS! Nothing was…

 IP passthrough is really like a bridge but done differently so what ever IP you would of got by bridge you get in IP passthrough but most Cellular networks give you a 10. IP
