This is an update to my previous post I installed DD-WRT on a Netgear WNDR3400v2. There’s a new DD-WRT firmware available for the Netgear WNDR3400v2 available over at MyOpenRouter.com. I haven’t flashed my router with it yet but a friend Dave Compton has and he says it’s smooth sailing. Below you’ll find a few e-mails we shared back and forth on the topic. The bottom line here is that if you’re considering using DD-WRT on your WNDR3400v2 you should use the firmware from this post linked above (and below in the email message) instead of from my original post.

I’ve been using the new version for a week or so without any problems.  The major benefit for me is just that I’m running a more up-to-date version which I assume ( hope ) has bug fixes that the earlier version did not.
Aside from that, the only benefit that I see is that the default iptables includes a rule that implements “NAT loopback”. Previously, I had added a similar rule by hand to accomplish the same thing. In fact, the ability to do that was my primary reason for installing dd-wrt in the first place. Given that I already knew how to do this, it’s not too important to me now. However, if the previous version had had this rule built in, it would have saved me some trouble – and cost me a learning experience.

—————————— ——————- So far I’ve been using the earlier version since January with no problems. Every now and then I wonder if using a version of dd-wrt that’s was created by “some guy on the internet” more than a year ago might not be a good idea though. Today I looked and saw the update.

download/44198/DD-WRT-for- NETGEAR-WNDR3400v2-With- Heartbleed-Protection/ I’d feel better about the binaries if I downloaded the source and built it myself but from what I’ve read that looks like it might be tricky.  But at least this version is much more up-to-date.
I plan to try it out over the next week or so. If I do, I’ll let you know how things work out. If you get there first, please let me know.
Thanks.

Nope. I haven’t. My WNDR3400v2 hasn’t faltered in it’s operation in the slightest so I haven’t bothered with updates. Does the new version provide any worthwhile enhancements? If so, I’ll give it a go.
The only feature I really desired out of the box was some real NFS support instead of that crap FTP resource they provide to allow access to the USB data store.

Hi Josh,I just noticed that there is a new version of DD-WRT available for the WNDR3400v2. Have you tried it out yet? I’ll probably try it myself but I wanted to ask you first.

flashed this (latest) and went without a hitch. any idea on how to enable NAS with my usb drive?
flashed this today, working good so far. lots of new stuff to get in to compared to the stock netgear firmware.
I flashed this and everything is good. Any chance of finding a way to toggle the blue light on top without physically cutting it internally?
i ended up disassembling the router and placed electrical tape over the small LED’s. problem solved.
Where are the current instructions for flashing? One page says its out of date and refers to this page. But I can’t see any instructions on installing here.
Thanks!
I don’t recall the exact directions I followed, I performed this several months ago, but I found these instructions.

I found it while searching for instructions on unbricking my router, i tried a different firmware and did an erase.
I cant seem to get portforwarding to work. I have DMZ enabled to my ps4 but whenever I go to play some games it says that my NAT is still moderate. Anybody know how to fix this?
WNDR3400V2 DD-WRT: OPENVPN Private Internet Access:
Having trouble getting all machines routing through PIA via DD-WRT, anyone worked a solution for this problem?
Port forwarding, dmz, nor qos seem to work. I can’t set a limit on bandwidth this firmware.

I have never used dd-wrt and have the wndr3400 v2 that has stock firmware version V1.0.0.54_1.0.82. I would like to try to put it on my router so I can add a vpn. However if I brick it I may need stiches after my wife uses the brick to bash my head in.
