IPTables err with TRACEROUTE
 

I get a confiuration error when setting up my firewall with IPTables. The lines that are causing the problems are:

# OUTGOING TRACEROUTE
# -------------------
# Commented this out to see if this was the issue 1
iptables -A OUTPUT -o $EXTERNAL_INTERFACE -p udp \
-s $IPADDR --source-port $TRACEROUTE_SRC_PORTS \
--destination-port $TRACEROUTE_DEST_PORTS -j LOG
iptables -A OUTPUT -o $EXTERNAL_INTERFACE -p udp \
-s $IPADDR --source-port $TRACEROUTE_SRC_PORTS \
--destination-port $TRACEROUTE_DEST_PORTS -j ACCEPT

I ended up commenting them out but want to figure out what the underlying issue is. The error states that there is a problem with the UDP --destination-port.

If you need the rest of the file I can post it - its big though.

Thanks in advance.

:scratch:

post the values for all variable (mainly $TRACEROUTE_DEST_PORTS)

No entry in code
 

I am using the http://www.linux-firewall-tools.com/...all/index.html tool to configure my iptables - it does not list a variable for the TRACEROUTE_DEST_PORTS or TRACEROUTE_SRC_PORTS. Not sure how I should code these variables.

The TRACEROUTE_DEST_PORTS would vary based on the traceroute inputted and the TRACEROUTE_SRC_PORTS would be either my internal (eth1) or external IP (eth0).

Thanks,
David
