Hi chaps Had a bit of a google, and of course consulted Ziegler, but I'm still not 100% on either of these, so --- 1) can iptables use eth0:0 as a valid interface distinct from eth0 ? So I can use eth0 as LAN internal i/f and eth0:0 as DMZ internal i/f. and ... 2) Back when I did my checkpoint certs we covered "static NAT" - simple one-to-one address translation, rather than "hide NAT" - aka iptables SNAT / MASQUERADE.... ...the question I have is - is the example given in Ziegler starting on p280 and table 7.1 "Host Forwarding to Servers in a Privately Addressed DMZ" an example of "static NAT"?
