The -S option is only available on the ARM routers.....for the MIPS routers use iptables-saveAlso, iptables -S (note the capital S) definitely works for me on my 87U. Reboot your router. I suspect where you have kept running the iptables rules you have caused massive duplication of rules.

Can you try connecting a different client and seeing if the same thing happens?
So depending on what you're doing, might be worth double checking the options you're adding to dnsmasq (even if you're on the same subnet, you still have to tell dnsmasq to listen on other interface vlans as it won't listen to them by default).

What device is the one with the issues? I would check it's network adapter config - something isn't playing nicely.
Schemerg, are you able to replicate the problem if you decrease lease time and wait for a renew?
I decreased lease time to 60 seconds (and rebooted the router) and then connected without problems. The system logs on the router show the initial offer and acceptance of the dynamic IP, and a further DHCPREQUEST every minute after that to renew the lease. I put the laptop to sleep and woke it up and again the IP was handed out again and renewed fine.I'll give a try this weekend and report back...
