I have a Mandrake box serving as a NAT/Firewall box.

My IPCHAINS ruleset is as follows:
default incoming policy of REJECT
remote interface, any source, going to WAN interface address is valid
outgoing policy of reject
local interface, any source, going to LAN is valid
forwarding policy is DENY

If I wish to offer a service on the Linux box to the outside world, need I
configure IPCHAINS to allow access to that service? For instance, if I wish
to offer SSH on port 22 from the WAN, must I specifically allow access to
that port?

Regards,
Nathan
