How to NAT - WR21

0 votes
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, I want the modem to translate that address so the ping request is sent to Is this possible? Further, I'd like to setup a NAT table: = = =

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 -> to

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
