I am running dd-wrt (DD-WRT v3.0-r40559 std (08/06/19)) on a Linksys 3200ACM router. I attempted to set iptables rules by ssh-ing into the router and blocking all traffic.
The command I issued was :
iptables -P INPUT DROP
In hindsight, this was amazingly stupid, because I was immediately booted from my session and I can no longer connect via ssh. The router is currently allowing all outbound traffic, but I can no longer administer the router. I have reset the router several times (holding down the reset button) and this does reset the system. After reconnecting to the admin page at 192.168.1.1, it prompts me to set a new password. However, after I set a new password, I cannot navigate to any of the other web pages or connect via ssh. Any thoughts on how I can reset my router to either the factory linksys or initial dd-wrt firmware?
Also, I've already tried the 30/30/30 reset. No dice.

You don't need to 30/30/30 the 3200ACM. Press reset for about ~10 seconds or so and release. Also, that is not an ideal build.
