Hi, I help maintain the servers for a large vBulletin forum (usually 500-1000 concurrent users online), we currently have 3 servers (1 sql, 2 web servers running lighttpd) and recently had a hardware load balancer installed.
The problem is the load balancer acts as a reverse proxy, and vBulletin/the webservers see all requests as coming from the load balancers ip rather than the users ip - which means vBulletin sees everyone who isnt logged in already as the same user which means it's incredibly hard to login (due to people getting their password wrong etc), search, and keep track of users from their actual IP's.
According to our datacenter the original source IP is sent to the webservers in the X-forwarded-for header, is there anyway to get vBulletin to use this header instead of the normal one it's using?
