Hi all,
wow can I configure NAT on Mikrotik bridge that is working as a wireless client ? I need to get simmilar functionality as on any simple "wireless bridge". The result is that all IP traffic of ethernet clients is NATed to MAC address of wireless interface of the Mikrotik. I suppose that I need to configure src-nat rule on bridge firewall but how? And especially how to handle ARP requests ?

chain=srcnat src-address=(lan) action=masquerade

Is it NAT rule for bridge? How it handes ARP requests? It seems to be only IP masquarading.

I am sorry, you probably do not know what I am talking about. I mean MAC translation, not IP. Please anyone if you know how to configure bridge NAT to correctly handle ARP and MAC translation, please answer.

OK, sorry, I'll try to explain better: I would like to configure MikroTIK to the same functionality as a simple "wireless bridge client" device.

So, in following configuration:

users <-- ethernet --> MTclient <-- wireless --> AccessPoint <-- WAN

if there are more IP users, all are accessing WAN with their IP addresses but MAC address is substituted by MAC address of MTclient.

I can try to explain it saying that I want to simulate the same functionality as a simple wireless AP (e.g. Ovislink 1120 or 5460 or many other simple wireless AP) configured as bridge and connected as wireless client. Any IP device connected to it's ethernet port can communicate through wireless link using a MAC address translation.

I do not know to explain it better
