We currently have a Cisco UC520 that I've repurposed as our router. Long story, but we are looking to replace it with an actual router, and i'm looking at the Cisco RV325.
On the UC520, I was able to configure secondary static IPs on the outside interface using IOS commands. The lines in the config output look like this:
ip address xx.xx.xx.131 255.255.255.248 secondary
ip address xx.xx.xx.132 255.255.255.248 secondary
ip address xx.xx.xx.130 255.255.255.248
ip access-group 104
Then in acl 104 i was able to create rules like the following:
ip nat inside source static tcp 10.1.x.x 21 xx.xx.xx.130 21 extendable
ip nat inside source static tcp 10.1.x.x 25 xx.xx.xx..130 25 extendable
ip nat inside source static tcp 10.1.x.x 80 xx.xx.xx..130 80 extendable
ip nat inside source static tcp 10.1.x.x 80 xx.xx.xx..131 80 extendable
ip nat inside source static tcp 10.1.x.x 443 xx.xx.xx.131 443 extendable
ip nat inside source static tcp 10.1.x.x 2222 xx.xx.xx.132 2222 extendable
So in the 104 acl i was able to reference all the IPs assigned to the internet facing interface and create independent firewall rules for each.
1) Does the RV325 only have a web gui? No IOS CLI access?
2) I've been looking at the online emulator, but i don't see a way to setup multiple static IPs on WAN1. Is this possible? If it is, will i then be able to create firewall rules referencing the different IPs or does it only allow you to select "WAN1" as the interface. Everything i find online seems to suggest using 1to1 NAT, which seems like a DMZ type setup where you map 1 public WAN IP to 1 local LAN IP, and therefore the server is directly exposed to the internet.
