Hi Cloudcomputer,

I've been following development of Mikrotik and hoping to get a unit soon to replace my existing Dlink. There's only 1 concern and I wonder if you could answer it for me.
We are using Unifi Biz20 with 5 public IP for 2 years, and as you might gussed the throughput on Dlink615 is very bad. TPLink with DDWRT or OpenWRT doesn't have an answer to my concern, writing to Mikrotik Malaysia also not giving me solid answer.

If you know what I'm talking about, yeah.. the Dlink is irreplaceable due to their firmware which allow bridging from WAN to LAN hence allowing 5 public IP addresses assigned on the LAN port (instead of NAT/PAT). So I wonder if you could tell me Mikrotik RouterOS can do the same as Dlink?

Thanks.

Thanks Cloud computer,
There is an overhead with NATing (which I dislike) suggested. The NATing at layer 3 consume memory and processing power (especially when number of IP sessions exceed few hundreds thousand). Both URLs is suggesting NATing while what I am looking for is layer 2 bridging capability. No filtering, no NATing, no ACL is required, no routing... just bridge the WAN interface through.

Eg:
Network/subnet id: 212.212.212.0/29
ISP Gateway: 212.212.212.1/29
Router WAN: 212.212.212.2/29
Router LAN (or host ip): 212.212.212.3, .4, .5 and .6 #WAN and LAN is bridged
Broadcast: 212.212.212.7

Any clue? I don't need IP feature set (firewall/PBR/LB) but just dedicated WAN bridging feature. Funny though, Dlink615 can do that...

Cheers and thanks for your input.
