Hi All,

I have a problem with my firewall settings.

Currently, tproxy cannot work with with FTP in active mode.

In my firewall settings, I have
	# Allow packets that belong to tproxy pass.
        iptables -A INPUT -m tproxy -j ACCEPT    # Accept all traffic
for tproxy??

        #### Default Drop everything in INPUT chain
        iptables -P INPUT DROP				# NOTE the
default DROP policy
        iptables -P OUTPUT ACCEPT

For Active FTP, my proxy server is listening on behalf of the connected
client but somehow the FTP server cannot connect back due to the
firewall DROP policy on INPUT.

What I want is to accept all tproxy traffic even with the default DROP
Will "iptables -A INPUT -m tproxy -j ACCEPT" impose any security

Thanks very much for any help.
