Problems with DNS and Proxy

by graham . Updated 19 years, 2 months ago

Since 9 May this year, I’ve been having issues logging on and maintaining my login at forums based in the USA. This is in particular at www.pro-networks.org but also www.planetamd64.com and www.neowin.net where I am a member. I thought this may be a phpbb issue at PROnetworks but PlanetAMD is an IP.Board, as is www.neowin.net and I’m experiencing the same issues on them all.

What happens is that my last visit is continuously adjusting to current time and as a result I lose all New Posts. I also get numerous “Invalid Session” messages and am logged out whenever I go to a private staff or management forum and then need to log in again before I can enter. As a management staff member at PROnetworks, it’s critical that I carry out admin functions there and with this problem I’m not able to login to the phpbb Admin panels to do that, as I get logged out constantly and end up with invalid sessions and then need to re-log on and get into a loop never actually being able to do anything.

Making a new post is very difficult there too as I get “Invalid Sessions” and need to re-submit the post many times before it accepts and goes through.

Clearly this is not only a phpbb issue as the other two sites where this is occuring are not phpbb forums. This does not occur on vBulletin forums though.

Locally here in South Africa I have no such problems at all even on phpbb based forums.

Once before about 18 months ago I had similar issues and solved them by using dsl-cache.saix.net on port 8080 as a proxy as well as specific DNS and alternate DNS Servers on my network card. This worked great until the 9th and then this problem started.

I’ve also tried to use some of the free proxy sites based in the US without any success. I’ve tried using OpenDNS servers (inputed to the wireless NIC)and the same proxy as above but on a different port : dsl-cache.saix.net port 3128

I have to use a dynamic IP address as the cost of obtaining a static one is ridiculously high over here. The lowest cost way I have access to a static IP address is to lease a diginet line for which I have no use at all.

Does anyone have any idea what the cause of this is and how to remedy it?

All input will be greatly appreciated and should you require more information please let me know. Thank you.
