Indeed you can. It means exactly what the man page says it means. (Apologies if that sounds harsh, but reading the documentation first normally helps...). > is it = -j REJECT? Not at all. >From the documentation: <quote> RETURN means stop traversing this chain and resume at the next rule in the previous (calling) chain. If the end of a built-in chain is reached or a rule in a built-in chain with target RETURN is matched, the target specified by the chain policy determines the fate of the packet. </quote> hth Adam
