I have iptables and masquerading enabled through this:
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
How can I revert this rule? i.e I want to disable the masquerade.
I am afraid to test..because if I fail..there would be a lot of problems (for example lose ssh)
Also can I restart iptables hoping that it wouldn't start rejecting all conns.
