turned off firewall on Host1, Host2, and Host3?

|Host 1,2,3 can ssh Router but when I try to ssh any of

|ssh:connect to address xx.xx.xx.xx port 22: no route

These are 4 Red Hat boxes?

If the router can ping any host, but can't ssh to them...
- that is odd
apparently your routes are set up right, I'd just verify that you actually
have ssh working and running on each Host on the default port.  from each
host, "ssh localhost 22" and "cat /etc/ssh/sshd_config | grep Port"

veryify you can connect to them by another means, if they are running
webservers... "telnet (localhost/ip) 80 (enter)... HEAD / HTTP1.1
(enter)(enter)" or run some nmap scans?
