If you ping another destination during the "hang" - does it work? If you ifdown and ifup the interfaces (wan + lan) on the router after a hang - is it released? an icmp packet is short so i don't think this is the case but: what is the MTU on the lan/wan?
Also, use a tool like mtr http://en.wikipedia.org/wiki/Mtr_(My_traceroute) to detect any packet loss along the route. 2009/5/27 Erez D <erez0...@gmail.com>: > hi > > i have an openwrt (linux) router, with regular firewall rules (nat, > related+established,clamp-mss-to-pmtu, etc). > > if i ping from the router to the internet, it works ok > however if i ping from inside my lan to the internet, the first 30-70 pings > works, then it stops working (i.e. 100% packet lost after the first 30-70) > using tcpdump inside my router shows the icmps going through the wan > interface but none come back. > > any idea ? > erez. > > _______________________________________________ > Linux-il mailing list > Linux-il@cs.huji.ac.il > http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il > > -- Frank Lloyd Wright - "TV is chewing gum for the eyes." - http://www.brainyquote.com/quotes/authors/f/frank_lloyd_wright.html _______________________________________________ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
