This is my first time using DD-WRT, and just so happens the newest beta release is today haha. Anyways, used previous build (r52369) instead and it is working fine now. Here are the details:
To install, I first reset my router to factory settings and then updated firmware using factory-to-ddwrt.bin file from latest r52432 build. Once updated, changed password, and reset DD-WRT to factory default to clear VRAM or whatever. After this, I reset my modem. DD-WRT then showed my WAN as 192.168.100.10, which I think is normal. I rebooted router from admin panel, and after this it had a valid WAN IP.
The modem and router internet status indicators showed connected, and so did my computer, however, if I actually tried to send any requests (ICMP, TCP, etc.), I did not get any replies. Interestingly, if I pinged a domain like google.com using CMD (Windows), it was able to resolve the IP address, but no replies. I think this is why it showed connected, I'm assuming it determines connection status by sending a DNS query or something.
Thanks to all build thread reports, and @hvanderkruijf (Henry) investigation, IPv4 iptables issue is nDPI (xt_ndpi).
So as a temporary solution or workaround anyone using r52432 can add "modprobe xt_ndpi" to the startup script.

If you use ndpi xt_ndpi.ko is insmodded by the firewall.
It looks like that the adding of the risk option: https://svn.dd-wrt.com/changeset/52427 needs xt_ndpi.ko which is not available if you do not use ndpi.
So maybe the risk option needs some tweaking to only kick in if you really use ndpi?

I had no success with R7800 ... 52411 or (even 52369) > 52432 R7800 went "numb" (no reset)
I had:
GUI and SSh access...
there was correct NTP time
there was wget and curl working...
but no connectivity......
reverted to 52369
I haven't tried reset and manual recompile of 52432 as this is a heavy load unit...no time for it atm sorry..will pass for now

I'm check the DD-WRT project have included an old version of Iptables. In the firmware is version 1.8.5 and the newest version is 1.8.9. Have you got plan to update it ? Configuration of DD-WRT provide use iptables and when it is activated on dd-wrt ip6tables is activated too even when IPv6 is totally disabled. That useless solution in my opinion because wastin router sources. Have you got plan to use more optimal solution for iptables ? In changelog I'm found fixes for old iptables module. In my opinion update iptables module to 1.8.9 version is rather good idea.
