Attached is an example from one of my routers. There is more stuff
that you can do with it but I have not investigated it.
--asp
firewall {
filter ssh {
term permit {
from {
source-address {
198.6.255.0/24;
}
protocol tcp;
destination-port [ ssh telnet ];
}
then accept;
}
term deny {
from {
protocol tcp;
destination-port [ ssh telnet ];
}
then {
count ssh-deny;
log;
reject port-unreachable;
}
}
term remainder {
then accept;
}
}
}
