Sky Hub blocking connections between ethernet ports

[Fred27m]

I've been having a lot of trouble with my wired home network after switching to Sky broadband. I've been doing a lot of digging and think I have got to the root of the problem.

The Hub (SR203) allows pings betwen devices (IPv4 and IPv6) and also seems to allow port 80, but if I try to map network drives, access a web page on port 5000 on my NAS... nothing.

I have a few devices connected via one network switch going to one ethernet port on my hub and some more devices connected via a switch on another port. These two networks work fine and can connect out to the internet but communicatin between them (or WiFi devices) is blocked. Connecting devices directly to the Hub seems to help, but it's NOT the switches.

I've looked at firewall settings on the Hub, but as expected these are for rules between the WAN and LAN so have no effect on traffic between LAN ports.

Anyone know of a fix - or a better router than works?

Also posting this up in case anyone else is having the same frustration. My workaround will probably be to go with another switch behind the hub so the hub doesn't get involved with internal traffic.

@Fred27m  Way back when I used to run sky's kit.

The only reliable fix I found was to create a run a DDNS service on your Nas,

Then point your connections to your Nas via it's host name (+port #  if needed) rather than it's ip.

I had the same issue many years back & the sky supplied router(s) ER110 & SR203 were a pita.

Syno's ddns is free & easy to set up, then give yr nas a reserved ip if you haven't already & your good to go 👍
