Subject: All interface specifications being replaced by ANYWHERE
Date: Fri, 09 Dec 2005 15:17:11 -0800	[thread overview]
Message-ID: <001c01c5fd16$af0deb40$0201a8c0@shodan> (raw)

Hi All,

I recently redid my home gateway/NAT box with debian 3.1, and everything
looked to be working fine until I did a quick scan on it from outside to
test the firewall. All the services running appeared to be exposed. Checking
my rules with iptables -L, I found that for some reason, everywhere I had
specified a physical interface, it had been replaced by ANYWHERE.

For example, the following rule:

iptables -A INPUT -m state --state NEW -i ! $EXTIF -j ACCEPT

Ends up appearing in the iptables -L list as:

target     prot opt source               destination
ACCEPT     all  --  anywhere             anywhere            state NEW


Needless to say, this doesn't make for a very good situation. Has anyone
ever seen a problem like this before? Any suggestions would be greatly
appreciated.

Thanks,
Grant
