I recently switched from Tomato to DD-WRT and seem to be unable to reach internal services via my ddns domain. I have Filter WAN NAT Redirection unchecked, but I am unsure of what other settings I might need to adjust. Google searching seems to reference mostly older articles like https://superuser.com/questions/285699/dd-wrt-how-to-allow-port-forwarding-to-apply-to-requests-originating-from-insid.

When I tried, it seemed to break everything.

I am currently using 35244, but I don't use the wifi on my Asus N66U. It is stable though.

Unfortunately there seems to be something fairly wrong with the recent builds.

I get the same disconnects on my RT-N16 using

DD-WRT v3.0-r35244 big (03/05/1

Again, to be more precise, 34876 gives random wifi disconnects on RT-N66W and 35244 has the same problems on RT-N16.

The dd-wrt itself appears to be stable, more or less i.e. I can log into the router, connect via VPN, and so on.

The only other symptom I see is that devices on my LAN seem to spontaneously be unable to see each other. It may be that there is something wrong with ARP for wifi connected devices.

I never had these issues with 2.4 builds on these routers in the same environment.

(I am trying to upgrade to a 3.0 build so I can use Entware.)

DD-WRT v3.0-r35244 big (03/05/1 the disconnects seem to be lot worse on any band and more frequently then in the past. Is there anything wrong with using k26 if it is more stable? Any recommendations on a stable version? I never had these issues with tomato, the only issue I had with tomato is during large downloads the internet would seem to crawl or halt. Well and it's not developed anymore.

I've been thinking about going to Merlin, but I need to learn more about how to customize it first as it seems to be less GUI configured.

r33492 seems to feature stable wireless.
I got no WLAN disconnects for about a day.

[Per Yngve Berg]

What CFE version do you have?

1.0.1.3-9 is working
1.0.1.2 is not good.

[Laryllan]

I'm using 1.0.1.9
Had to update it using the Merlin FW to get the device working with DD-WRT at all.

Here's a link to the update instructions:
