I found that the factory firmware of TP-LINK WDR4300 had some annoying problems, such as failed on using PPTP/Cisco IPSec, disconnection on WAN for using BT on a certain time.
I am thinking about changing to use DD-WRT. However, I bought WDR4300 because of hardware NAT.
Can dd-wrt use the hardware NAT of this router? Thanks.
It's not the speed my friend, it's the number of packets per second that matters
so what is the limit with or without HW NAT?
I'm interested in this topic too. I have a WDR4300 and flashed it with DD-WRT and was overall quite impressed, but WAN throughput on my 150MBps cable connection seemed to be limited to about 130Mbps. This was using my ISP's own speedtest facility which consistently returns 150Mbps figures with the stock firmware.
I'm due for an upgrade to 200Mbps soon, so I'd like to know too whether there's anything I can do to achieve my full WAN speed on the WDR4300 with DD_WRT.

no BUT, there is ddtb now, ddwrt turbo boost. if i understand the code correctly it only seems to be for k3.10 & up, it was removed from k3.5 probably cause it dont work. but i think wdr4300 uses k3.10 as does the wdr4900 _________________ LATEST FIRMWARE(S)

kong's builds for broadcom but the ddtb commits were done on the main svn tree for k3.10 & up & some atheros runs k3.10 so..im not sure if its using the actual nat chip or just using other methods but its something
Interesting.
Checking the Changeset's log looks like changeset 24556 is when this was introduced, just 4 weeks ago.
In changeset 24567 it said "shameless reimplementation of broadcom ctf nat acceleration driver"
It looks broadcom oriented. I wonder if this is something that would work on Atheros too.
Not sure if the broadcom and atheros hardware acceleration chips use compatible interfaces.
you could plug the WAN port into another gigabit router's LAN port and try "iperf" between two machines, one on each side of the router.
I don't have another gigabit router (and I haven't decided what to flash on my wdr3600 yet) otherwise I could test it myself.
I guess it's not a big deal anyway since that kind of bandwidth is not even available where I live (unless you pay an insane amount of money), but anything that can offload stuff from the CPU is probably a good idea if you plan to use the CPU for other stuff.
I think this feature could be a big differentiator for DD-Wrt since OpenWrt apparently has no interest in making any NAT offloading work anywhere.
