How to NAT - WR21

Digi TransPort WR (Series)

Dear Digi,

I’m not sure if NAT is the correct term, but I would like to translate IP addresses.

i.e. if I send a ping request through the modem to 10.1.0.1, I want the modem to translate that address so the ping request is sent to 10.1.1.1. Is this possible? Further, I’d like to setup a NAT table:

10.1.0.1 = 10.1.1.1
10.1.0.2 = 10.1.1.2
10.1.0.3 = 10.1.1.3
…etc

Right now i’m using a router to do this, which is messy and expensive, as it’s another piece of hardware in my enclosure. I was hoping the WR21 had this functionality built-in.

Hi you could do this in the firewall

pass out break end proto icmp from any to 10.1.0.0/24 -> to 10.1.1.0/24

you would need this on the interface close to the source so may be on eth 0 and you would need another rule to allow all other traffic

pass break end

hope that works for you
