Load balancing issues with IP.B

[N3X15]

Here is my current configuration:

I have 2 1U Pentium 4s (3.0GHz, 1GB RAM each) behind a NAT firewall, both systems running Lighttpd 1.4.something on gentoo linux with fastcgi and memcached. MySQLd is installed on the first webserver (which will soon change when I figure out how to make MySQL replicate onto the second server or if I get a third server for filestorage/mysql).

Unfortunately, because of problems with IPB logging people out when the servers are switched by the firewall's loadbalancing setup, I have had to disable one of the servers on my load balancing setup.

Is there a way to force IPB to use database/memcached-based sessions or am I stuck with filebased? Please note that I have tried to make PHP itself use memcached for sessions and it did not go over well.

Firewall setup:

pfSense 1.2-RC4
Pentium 3 (One of those recycled boxes)
512MB RAM

Server 1 Setup:

Pentium 4, 3.0GHz
1GB RAM
250GB DB storage, 500GB RAID1 filestorage, 250GB OS storage
Memcached

Server 2 Setup:

Pentium 4, 3.0GHz
1GB RAM
80GB Filesystem storage (mounts Server 1's filestorage over NFS)
Memcached


(I realize that my server configurations are highly varied, but that's what happens when one has a very low budget :/)

You'd have much better performance using dedicated mysql server, 2 fcgi backends and one webserver.
