ROUTER Sagemcom Fast 5464 and setting of Firewall.

[Billx]

I would like a newer version of the router firmware and the manual of the router. Usually this is done from the manufacturer. The manufacturer does not have any portal for firmware or manuals. Do you as the ISP have a portal to download new firmware and the manual?

Navigating within the router, there seem to be various faults. I am unable to set the firewall, as it doesn't offer the options required. There are various odd things appearing in the log within the router. I've read some of the posts in the community, and it seems it might be a good idea to disable wireless optimization. Some posts suggest that TalkTalk  are the only ones able to upload any firmware or disable wireless optimization. Does TalkTalk repeatedly monitor and download all my settings? I am not sure what's going on.

Thank you @Karl-TalkTalk. I'll have a little play with it, see if there is any change.

The only thing that 174 might address where the firewall is concerned is an issue where when 158 was updated to, the firewall was changed to high by mistake.

You can go to high if you want, but this is known to block access to some social media & other sites. Unless you have malware on your device, being behind a router is an excellent part of internet security. The only way that something from outside can target your device is if you have any port forwarding configured or UPnP being enabled.

Hi

I've updated the firmware to 174 for you.

Thanks  

Karl.

Thanks for the response @ferguson, @KeithFrench

The default setting is MEDIUM:

LAN -> WAN Allow all

WAN -> LAN Block all below NETBIOS

I think the HIGH setting is preferable:

LAN -> WAN Allow all below HTTP HTTPS FTP FTP-DATA DNS TELNET SSH IMAP IMAPS POP3 POP3S SMTP SSMTP NNTP NTP SMTP-AUTH IPSEC ICMP TRACEROUTE Video2Protect

WAN -> LAN Block all

HIGH setting is preferable, because it blocks a lot more from the WAN than just NETBIOS. But there is still a problem, because I might want to add or subtract something from that list. If I don't include a majority of of the protocols in this, then what is the firewall for?

So just including just NETBIOS in the default does not sound reasonable.

I will leave that for the time being.

The current version of the firmware is SG4K100158.  I believe there is a newer version, SG4K100174. Is it possible to have this uploaded to this router?

What are the system log messages that you are concerned about? If you want to paste them in your reply I am sure that I will be able to help with them.

If you can, as @ferguson has said, please can you state which firmware you are on, then I will be able to advise on any specific bugs that you think you are seeing with the GUI.

True there is no official manual, but...

[ferguson]

The router offers four firewall settings: Low; Medium; High and Custom. Medium is the recommended default setting, but you are of course free to change if you wish. Any connectivity issues resulting from that will be down to you though.

You haven't mentioned which firmware version you have, if you do then the support team can check and upgrade if required. This is not something which you can download as a user.

Finally, there is no manual,  although most of the options available viathe user menu are self-explanatory. If you get stuck with anything in particular we are always happy to help here.
