lynx not installed. PC's on the LAN can connect to the webserver and /login

Just waits, seemingly forever.

Worked! (until I tried SSH...)

Apparently worked then I guess I hit return too many times and I'm 
locked out again.

The output was quite verbose and appeared to be the same as from a 
server on a different network where everything worked.

Like I said, this worked before on a different subnet. We just had to 
change IPs for a faster connection. There is no DMZ, just the main 
network's router on one IP, the 5209R on another and some wireless 
access points on another two.

When I first looked the IP of the main network was locked out in Login 
ManagerI. I cleared that and expected the problem would go away, but it 
hasn't. The users are getting very tired of roundcube email...
