 |
Hi,My ISP is China Telcom, I share my ADSL with others via a Netgear WGR614 router.
When NATted Hosts detected over 3 Devices, web access is blocked,and browser gives a "Warm Tip".
I try to modify the IP Header TTL to 128, and modify the IP Header ID (IPID) to random value on Suse Linux,it work Perfect!
iptables -t mangle -I POSTROUTING -o ppp0 -j TTL --ttl-set 128
iptables -t mangle -I POSTROUTING -o PPP0 -j IPID --ipid-pace 1
Can DD-WRT add IPTables IPID Target on the last release?
