What may be going wrong for jg is something related to lots of tcp syn attempts, particularly over a he tunnel. it takes a really long time (24 hours) for the problem to occur, once it oc= curs, all syn attempts from a given interface (in jims case, 2.4ghz) never make i= t out the router. things like dns traffic continue to work. the only things looking at syns is the syn flood protection and (sigh) conntrack, I have disabled synflood protection on jims box and I guess I'll have some results in 24 hrs. If you get in a situation where dns works and attempts to use tcp outside the net do not, please take a capture of the offending interface. --=20 Dave T=E4ht Fixing bufferbloat with cerowrt: http://www.teklibre.com/cerowrt/subscribe.= html
