Merged: NTL DNS issues? - Page 4

ian@huth · 14-04-2005, 12:37

The ip of www.thetophouse.co.uk is 66.96.250.90 but you get a 403 access denied error if you try to go to the site using this from NTL connection. Sounds like one of the problems is that the site is detecting the ip address of the proxy rather than the individual and refusing access.

Hi

Yep just got off phone with NTL who say TopHouse have banned my ip - this aint true.

Dont really know what to do now................

Any suggestions?

OK, it looks like we have two symptoms of the same problem here, so threads merged.

It appears the best NTL's call centre chappies have managed so far is to suggest a customer's IP has been banned from the server in question. Can anyone take this further?

i can "telnet gladdy.co.uk 110" fine, but outlook just cant connect to it... But, if i put the ip into outlook, rather than mail.gladdy.co.uk, it works fine... This is really odd

Starting to look like it is DNS - any suggestions on why?

The only possible thing which could be blocked is burst's DoS software has blocked all ntl access, for some reason - but thats disproven by the fact you can access stuff by the IP address...

The problem is with the sites host who need to alter their ip checking to pick up the requestors ip address and not the ip address of the proxy they are being routed through.

What IP address appears in your command prompt if you type "tracert gladdy.co.uk"? Mine shows 66.197.154.165 but I'm on ADSL at the moment.

You should be able to confirm whether Burst is blocking NTL for sure by altering your local hosts file (windows system32 folder\drivers\etc\hosts) and adding the line

66.197.154.165 gladdy.co.uk

You may need to add your gladdymedia address too. If that gets through it will rule out Burst doing the blocking. If the tracert IP address shows something different than I've posted or that shown on dnsreport.com then that indicates DNS problem.

It does that for me also with the ip, no idea why, I'm not that technical, but not being on NTL I can get it fine just going in the normal way.

I'm added it to hosts, and it still doesnt work.. Guess burst are blocking them, for some reason.

ian@huth · 14-04-2005, 13:21

Just been trying a few random NTL proxies and I can connect to the site using some of them dbln-cache-1.server.ntli.net being one.

It definitely looks like the host site is picking up proxy IPs and blocking them.

I've spoken to burst, who have said they recently turned up their Anti-DoS gear, which maybe is why its becoming blocked? - If they have loads of connections from NTL proxies, because everyone of us uses that... I guess its picking it up as an attack, and blocking it

Hopefully they'll fix it soon.

Thread title altered subtly seeing as we're no longer so certain.

I freaked momentarily then realised you were referring to an NTL DIA / leased line, phew, thought you'd moved over to the dark side.

Yes I used the same proxy and it works alright. Haven't tried any others yet.

The Huddersfield proxies and Swansea work.
