Hi Dennis,
Did you add the firewall filter Security after you last logged in.
If I'm reading it correctly, it will permit ftp and telnet from a
single source and reject *all* other traffic to the RE. This will
cause no end of problems. You need to add some denies to prevent all
other telnets/ftp getting through and then a default permit.
Something like this should do the trick...
firewall {
filter Security {
term 10 {
from {
source-address {
194.53.244.18/32;
}
protocol tcp;
destination-port [ telnet ftp ];
}
then accept;
}
term 20 {
from {
protocol tcp;
destination-port [ telnet ftp ];
}
then reject;
}
term default {
then accept;
}
}
}
You've also got an entry for the broadcast address which is actually
specified as the network address (rather than the broadcast). You
really ought to fix that.
Regards,
Guy
