I suspect this is due to a firewall rule, but I'm afraid of locking
myself out of the system so I would appreciate some advice on what rule
I need to add/edit to allow me to connect to localhost at least to send
mail via SMTP. Some programs don't like the fact that they can't
connect to localhost (fetchmail... :-) Someone else helped me put
together my current list of rules.
Here's what I get:
$ telnet 127.0.0.1 25
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Permission denied
Here's my current rule list:
# Stop RFC1918 nets on the outside interface
$fwcmd add deny log all from 192.168.0.0:255.255.0.0 to any in recv
${oif}
$fwcmd add deny log all from 172.16.0.0:255.240.0.0 to any in recv
${oif}
$fwcmd add deny log all from 10.0.0.0:255.0.0.0 to any in recv ${oif}
# Allow any ip (tcp and udp) packets to go out the outside interface
$fwcmd add pass all from any to any out xmit ${oif}
# Allow established tcp connections from outside interface
$fwcmd add pass tcp from any to any in recv ${oif} established
#allows smtp
$fwcmd add pass log tcp from any to any 25 in recv ${oif} setup
#allows ssh
$fwcmd add pass log tcp from any to any 22 in recv ${oif} setup
#allows ftp
$fwcmd add pass log tcp from any to any 20 in recv ${oif} setup
$fwcmd add pass log tcp from any to any 21 in recv ${oif} setup
$fwcmd add pass log tcp from any 20 to any in recv ${oif} setup
$fwcmd add pass log tcp from any 21 to any in recv ${oif} setup
#allows http
$fwcmd add pass log tcp from any to any 80 in recv ${oif} setup
#allows https
$fwcmd add pass log tcp from any to any 443 in recv ${oif} setup
#allows pop3
$fwcmd add pass log tcp from any to any 110 in recv ${oif} setup
# Deny and log setup of any other tcp connections from outside interface
$fwcmd add deny log tcp from any to any in recv ${oif} setup
# Allow replies to DNS queries from outside interface
$fwcmd add pass udp from any 53 to any 1024-65535 in recv ${oif}
$fwcmd add pass udp from any to any 53 in recv ${oif}
# Allow outbound pings
$fwcmd add pass icmp from any to any in recv ${oif} icmptypes 0
$fwcmd add pass icmp from any to any out xmit ${oif} icmptypes 8
# Allow outbound traceroutes
$fwcmd add pass icmp from any to any in recv ${oif} icmptypes 3
$fwcmd add pass icmp from any to any in recv ${oif} icmptypes 11
# Allow ntp packets
$fwcmd add pass udp from any ntp to any ntp in recv ${oif}
# Everything else is denied by default, but let's log it too
$fwcmd add 65534 deny log ip from any to any
Thanks!
