Trying to use ipmasqadm
I am trying to use port forwarding on my Sparc 5. It has a 2.2 kernel. When
I try to use the command:
ipmasqadm portfw -a -P tcp -R 10.0.0.253 1723 -L 192.168.1.5 1723
I get the message:
portfw: setsockopt failed: Invalid argument
When I do:
ipmasqadm portfw -l
I get the messages:
Could not open "/proc/net/ip_masq/portfw"
Could not open "/proc/net/ip_portfw"
Check if you have enabled portforwarding
What have I not configured right to get the port forwarding to work?
