Solaris 10 SSH issues

Experts,

I'm having an issue where I can successfully SSH inside our LAN, but can't SSH from the WAN to Solaris servers. These are new vanilla installs of Solaris 10 v5.10 with 10_Recommended patch cluster 144488-17 installed. From what I can tell SSH installed with no problems as I can SSH to and from Windows, Linux and other Solaris servers, yet when I try to come in from the WAN I get a "connection timed out" error from Putty. Also I must mention that this error is intermittent in that sometimes a connection will work on box A and B, but Box C won't connect and vice versa. I can also successfully ping each server from the WAN with no problems. Where should I start troubleshooting?

Thanks

Did you setup port forwarding on the external router to allow port 22 traffic to hit the solaris 10 server?

check /etc/hosts.allow and see whether you have sshd:LAN_IP_range

try telnet <solaris_server> 22
and see whether the connection is in syn_sent or whether the TCP session is actually established.

The firewall has been configured to allow a range of the correct IP's. The weird thing is that certain boxes will allow ssh for a short time, then disconnect for no reason at all. I have no /etc/hosts.allow files on these boxes, are they necessary?
