I'm having some similar problems, what isp are you using btw? I'm using comcast in MA. I also recieved the drops on ports 67/68, the iptables fix didn't stop the issue with me. I upgraded to the latest DD-WRT v23 SP2 (08/17/06) mini. I even went as far as trying to get a new router Buffalo WHR-G54S because I thought my old linksys was starting to die. Unfortuanantly I'm having the same problem still.
even after using:
iptables -I INPUT -p UDP -i vlan1 --dport 68 --sport 67 -j ACCEPT
and verifing that the entry was put into iptables according to kiwi I am still getting drops on those packets. Which seems strange...
My ISP is Road Runner, but as I've stated, I don't believe the ISP is an issue at all, because I hooked the cable modem up to my PC directly, and then connected the PC that had the cable modem up to the WAN port of the router, and shared the connection.
When the connection dropped on machines hooked up to the LAN port of the router, it was still very happy on the machine hooked directly to the cable modem.
This seems to be a big issue, I've seen many threads popping up about this... and I might need to find a way to flash back to the original buffalo firmware, cause it's beyond tollerable.

I've seen the internet route stop passing traffic on a linksys, but a full reset/reflash/reset/reconfig fixed it. _________________ linksys GSv2, Gv4, Gv2, GLv1, G-TM, Buffalo wbr2, whr, whr-hp, whr-g125, wli-tx4-g54hp, Moto wr850gp, Alix.3C2
Jonathan, I set up the same router for a friend. He is experiencing the same problems. We can ping out of the router but not surf (port 80). I have been using his router at my address (same cable company) for a week now, no problems. I have not had a chance to take it back to his house and troubleshoot as of yet. He is using a eMachine that has an Nvidia 6100 series chipset. The onboard ethernet may be his problem, by chance are you running a Nvidia ethernet chip (drivers). The first thing I will do when I do go back is update to the newest drivers and if that does not work, I will further test with a old ethernet card.
The connection drops for every device on the network (from my PDA, to my laptop, to my wired PCs, to my slingbox) at the same time, and on all ports, not just 80.
So I don't think you are having the "same" problem that I am.
