I am running SuSE 9.3, default Kernel on my firewall machine and want to redirect client FTP requests to Frox proxy, port 2121 on the firewall machine.
In /etc/sysconfig/SuSEfirewall2, section 15 I set FW_REDIRECT="192.168.0.0/24,0/0,tcp,21,2121"
But nothing gets redirected. What did I overlook?
You want to say FW_REDIRECT="0/0,192.168.0.XXX,tcp,21,2121"
Redirect means redirecting to a port on the _local_ machine. The term you are most likely looking for is 'forwarding'. Have a look at FW_FORWARD_MASQ.
(?) for frox, the sytax is in the Readme.SuSE // To set up your packet filter, you will most likely use an iptables rule like this one: # redirect outbound ftp traffic from $int_dev transparently to proxy $iptables -t nat -A PREROUTING -i $int_dev -p tcp --dport 21 -j REDIRECT --to-port 2121 There is no need to recompile the kernel for this stuff. // Have i setup this with FW_FORWARD_MASQ ????.
