example: yyyy is the port you connect from outside, to get 192.168.t.z iptables -A PREROUTING -p tcp -m tcp --dport yyyy -j DNAT --to- destination 192.168.t.z:22 remember that ssh client would complain that fot the same address there are 4 different keys . you could set on your remote host a hosdt file containing the names for the three remote server, such a.b.c.d hiddenservera a.b.c.d hiddenserverb a.b.c.d hiddenserverc where a.b.c.d is the address of the gateway. > To UNSUBSCRIBE, email to [EMAIL PROTECTED] with > a subject of "unsubscribe".
