"Remember me" across IP addresses.

[squarefractal]

The network I'm currently on rotates its IPs every few minutes for the purposes of load balancing; and whenever the rotation occurs, I'm logged out. I tried checking "remember me" on the login form to prevent this, however, it appears not to work and I'm logged out each time the IP rotates.

Is it possible to have the "remember me" option work across different IP addresses?

It's not possible if your IP changes across class B boundaries. This is a security measure to prevent replay attacks.

Would it be possible to change this policy on your end for a specific set of IP addresses that this network uses?

No, that's not possible unless the security is completely disabled; this is the way phpBB is designed.
What you should probably do to avoid these kinds of headaches (and the same happening on other websites that apply similar protection) is to "anchor" your public presence with a private proxy or VPN. Then it won't matter that your actual public IP changes.

That's a very strange network design. And bound to cause problems all over the place for its users.
