NAT on the subnet...

RouterOS General
1

Hi all..

i just fresh on the RouterOS user management or server (usually more in wireless bridge implementation).
Just wonder know, can i NAT the LAN /29 to the WAN /29 instead of i need to use /32 to NAT 1 by 1 in the RouterOS?

if can, how i going to do that… this to NAT all my LAN WiFi in order to allow me to monitor from Dude which it’s under the WAN ip range..

I’m not entirely sure I understood you right, but I think this does what you want it to:

1:1 mapping
If you want to link Public IP subnet 11.11.11.0/24 to local one 2.2.2.0/24, you should use destination address translation and source address translation features with action=netmap.


/ip firewall nat add chain=dstnat dst-address=11.11.11.1-11.11.11.254 action=netmap to-addresses=2.2.2.1-2.2.2.254
/ip firewall nat add chain=srcnat src-address=2.2.2.1-2.2.2.254 action=netmap to-addresses=11.11.11.1-11.11.11.254
