Kouta Ikari Ayanami pointed out some public networks use web filtering that blocks non-web associated ports. This was causing a lot of problems with using ACDB.
CSS would not load.
Images would not load.
When we moved to this new server, I only had one IP address. In such a situation, the only way to run multiple servers is by running them on different ports.
Port 80 is used for rendering PHP pages. Everything else, like static content, I like to move to another server. And since we have a dual hex-core server, it made even more sense to set up a firewall-level round-robin to spread the load evenly across many servers.
Anyways, I set that up using Port 81.
Then we finally got a /29 IP allotment, I couldn't quite figure out how to do the RDR NAT to make it work on another IP running Port 80.
Turns out, all I needed was this one line:
rdr on rl0 inet proto tcp from any to 199.187.122.187 port = http -> { 199.187.122.186, 199.187.122.187, 199.187.122.188, 199.187.122.189, 199.187.122.190 } port 81 round-robin
Now all that's left is spotting and repairing any manually entered :81 links in the source code.
