Sagemcom-FAST5364 - No internet on Guest Wi-Fi, incomming VPN blocked, cannot add port forwarding.

[Amlosjes]

As per subject,

I'm experiencing issues with the TalkTalk router. Not sure when they started, but they are definitely not working.

Router details:

• Model: FAST5364 3.00
• FW: SG4K100174
• GUI version 5.100.1

[Guest Wi-Fi]

When enabling and configuring the Guest Wi-Fi, either on 2.4 or 5GHz, you can connect but do not get a DHCP address assigned. This was working a few months ago and I only enable/disable is when we have, well, Guests.

After Enabling and saving settings, sometime the GUI also fails to respond, for example when you click on Advanced or MAC Filter.

I believe I'm not alone in experiencing this issue!

[Port forwarding]

When trying to manually add a new port forwarding rule, the interface always indicates "invalid IP address". The IP address is correct, and the device is on the network. This was possible before and working, why has it stopped.

For anyone reading this post and got the same issue: Find your connected device in the list under ethernet or Wi-Fi connected devices, click on it and then add a new rule this way. This rule will be accepted!

I believe I'm not alone in experiencing this issue!

[VPN connections blocked]

Recently needed to turn on the VPN server again, so to be able to access home network while out of the house. The connection is not working, like protocols are blocked. (This was after the above port forwarding issues was resolved). Tried with both OpenVPN and WireGuard, but both seem to not operate. Making an outbound VPN connection does work, just no inbound VPN traffic.

I believe I'm not alone in experiencing this issue!

[GUI]

If you make a change, but navigate away form the page and select Yes to accept that you loose your changes. Then the dashboard of the GUI gets really upset. It thinks there is no Wi-Fi configured (does not even show the 5Ghz settings, there are no connected devices, settings do not load when you click on Ethernet or Wi-Fi.

what is going on with these FW updates.

Does anyone have a FW update or downgrade that resolves these above issues. They did not exist before, so why now?
