List
What options are there when you have multiple IP addresses and 1 openbsd
4.1 box with two NICs acting as a firewall? The Internet goes into NIC1
and a switch (with boxes plugged in) goes into NIC2 (10/8 address
range). Is the alias command used in hostname.if files the only way of
utilising these multiple IPs and guaranteeing the openbsd firewall is
protecting the boxes plugged into the switch on NIC2?
and also, am I right in thinking rdr in PF is for forwarding individual
ports and binat is best used for directing all traffic to an external IP
to an internal address? can this internal address be a public IP or RFC1918?
apologies for stupidity of these questions
