Adding second subnet to single WAN
-
I've done quite a lot of searching and found much information but many of the posts seem to differ and I'm not sure what terminology I'm looking for at this point.
I have a 2.4.5 firewall up and running with two interfaces, WAN and LAN. On the WAN, I have a small /29 subnet with the first IP being used on the WAN and the rest listed under firewall, virtual IP's.
I was given another /29 that needs to be on the same WAN interface but since this firewall is in production, I'm not 100% sure how I should be doing this. I am also not sure what terminology I'm looking for to find the right article, document that would show me how to accomplish this.
I just want the new subnet to act exaactly like the first.

Well if this other /29 is attached to your wan. You can use any of these IPs in the /29 like you would your other vips.

@johnpoz The first thing I tried was to add each new IP as additional virtual IP's but that didn't work so thought I was missing something.
The DC does all the routing so I don't think I need to add the gateway for example.

Well get with the DC then.. If you created a IP Alias vip it would respond to arp for that IP. Sniff on your wan after you create the vip, and send some traffic to that IP from external.. Do you see it show up on pfsense wan?

@lewis I just tried again and you are right, that's all it took. Thank you for helping.
