Right now our forums see and main login see the same IP: xxx.xxx.198.77
DirectAdmin server see: xxx.xxx.225.106
The obscured parts are the same in both cases.
This causes a problem, as the session login expects the IPs between main login and server to match up, if not the login fails.
This is from your ISP, both IPs belong to the same organisation, somehow it changes between you logging in and then visiting the actual server. It is consistently these pairs which leads me to think it is something on your ISPs end causing it, maybe they kind of sends your traffic through some kind of proxy service, I don't know, I just know the facts I see on our end.
