I'm having a problem getting port forwarding working. This is what happens (as root): ipmasqadm portfw -a -P tcp -L <local ip> <port> -R <remote IP> <port> results in portfw: setsockopt failed: Invalid argument ipmasqadm portfw -l results in: portfw: setsockopt failed: Invalid argument Could not open "/proc/net/ip_masq/portfw" Could not open "/proc/net/ip_portfw" Check if you have enabled portforwarding I have a RedHat 6.2 system with a custom 2.2.14 kernel. Masquerading works alright so I'm wondering whether I missed an option while I was compiling the kernel or whether I installed ipmasqadm wrong. rpm -qa | grep ipmasqadm results in ipmasqadm-0.4.2-3 Are there any other tests to determine whether I compiled the kernel with this option?
