Install with non /24 subnet mask

[zkosn]

Search didn't exactly come up with bad news, but no good news.

My home network uses a /18 mask (255.255.192.0) and I wanted to give amahi a try, but a /24 is not an option in my network. I'm a Cisco engineer; a /24 is not enough.

It's pretty clear that the installation can't handle a non /24 mask, but can it be changed immediately after install?
