4od through Smoothwall
Has anyone got Channel4 OD working through their filtering system? We're using Smoothwall and it doesn't seem to be blocking anything, yet we get the connection timeout error on everything we try and play.
I've searched through the posts here and there seems to be have been issues with 4od through a proxy server but I'm wondering if this had changed?

You may need to open port 1935 (on your firewall, smoothwall or otherwise) as it uses RTMP...

Ahh right, sounds like it might be an LEA issue then

Can anyone else get 4od working ok in their network? Can't see why it won't work here.

Can you connect a laptop with a direct feed to the LEA?

I can confirm with Tom, our ISA has a rule to allow port 1935 for 4oD.
Hope this helps.

Hmm, all our web traffic hits a Smoothwall box, and everything else hits and ISA. Can't see 1935 being blocked anywhere here!

This will confirm if it's you or the LEA, I'd try this before doing anything else.

Unfortunately not - all web traffic is only allowed via the Smoothwall box. Everything else (through the ISA) is only for access to LEA local systems (coporate networks)

Is there any way of checking if Smoothwall is passing requests out over that port (1935)?
20th January 2011, 08:34 PM #12
Sounds like you are using smoothwall just as a web proxy - in which case 1935 won't be hitting it - and its either your gateway (I assume ISA) or the LEA...

Actually it looks like I'm a bit scuppered on this. All of our clients use a central router as their gateway and have the Smoothwall box as their web proxy. Any non-http traffic that hits the router is forwarded on to the LEA's internal servers (via an ISA box which uses NAT) if it matches a particular IP address/range that relates to an LEA one. Everything else would be dropped by the router.
So I can't get Windows clients to use the Smoothwall box for port 1935 access, and I don't think the router will allow me to route based on remote port type, plus the range of IP addresses Channel 4 use is varied so I can't route based on IP address or range! I can't think of anthor way around this unless someone has a better idea?

sorry to derail to ISA but:
Could you please provide me with the rule/s you are using in ISA.
I have tried many times, with no luck so far.
Adverts play but no content.

I created a User Defined protocol called 4oD. I've attached a .bmp of the parameters.
I then created a rule allowing protocol for all users anytime from internal to external. Hope this helps.
