1:1 NAT and VIP's
Ok, so I'm confused when you need to use a VIP. I have read several 'how to's' describing setting up proxy-arp's/carps's and using a VIP. I've even read a comparison about monowall's 'Server NAT' being the same as 1:1 + VIP.
In my experience though I did not have to use a VIP for additional some static IP's on my WAN interface. I simply configured a 1:1 NAT, some firewall rules to let in certain ports from the Internet, and everything seems to work. Is that right, or do I need to make a VIP for some reason as well?
I did make a VIP for some clients outbound and used it in the advanced NAT configuration. That makes perfect sense to me. Just confused about 1:1 NAT's and if they need a VIP for some reason as well?
