So I have this weird set of problems, specifically three, with my network. Nothing that stops day-to-day work but I want to be able to fix them.

1) I cannot update the EPG on my Tivo. I gete Error N17, have done for months. Mucked around with DNS, IP (it's currently static) with no joy
2) iPad - Microsoft News and Money apps. Certain pages fail to load, give an error. Works 100% on other WiFi networks
3) Spark Thanks page - when looking for Movies available to buy tickets for, I getting a spinning wheel forever

I am pretty sure there is something on the network stopping these from working, but cannot yet figure it out. Configuration is:

BigPipe UFB -> Chorus ONT -> Untangle Server -> 3Com Managed Switch -> UniFi AP

There are no rules I can see in Untangle, and I have tried turning off the firewall to fix the Tivo problem, but no luck.

Anyone have any ideas? Everything else (web, Netflix, Hulu, Unblock-US, downloads, Email (I run Exchange at home), uploads to AWS Glacier, Sickbeard downloads, etc. work 100%.

Not sure if this is your problem but I was experiencing similar things on my network quiet recently.

I wrote about it in the Geekzone login thread.

In the end my problems were being caused by some filters which had been enabled on my router.

- Filter Cookies (Identifies HTTP requests that contain the "Cookie:" string and mangle the cookie. Attempts to stop cookies from being used.)
- Filter Proxy
- Filter Java Applets

Make sure none of them are ticked.

If that does not work, double check the time settings on your Ipad and Windows machines. I have also seen weird things going on when the clock is slightly out.

Mattmannz: What DNS are you using?

On Untangle - Peer DNS (i.e. what comes from the external interface from BigPipe)

On the Tivo - Static IP with the DNS supplied by the router (Untangle)

On my Laptop - Static IP and Unblock DNS

What type of NAT does the untangle server use? As it might be using "symmetric NAT" (hope I got that term right) Where each outgoing connection uses a random port. This breaks most NAT transversal methods. And some CDNs.

And it would explain why your devices work when connected to a different internet connection. As the other connection will be using a different NAT type.

There used to be threads on the Spark forum about people complaining about certain games ect not working with the Technicolor routers. It was due to these routers also doing symmetric NAT. Wouldn't be surprised if the reason Spark switched to supplying Huawei routers instead, was due to them getting sick of people complaining about things not working with the technicolor's but working with other routers.
