tova go znam az :)))       Ama problema mi beshe drug. Nqkoi subekti izpolzwat
TOS i precendence poletata, za da delqt trafik (peering i mezhdunaroden
naprimer). I ako poglednesh v route map'a na cisco IOS-a shte vidish che
kato TOS mozhe da se zadade chislo ot 0 do 15... A standarten TOS ne e
nai-udachno da si slagash, shtoto naprimer ako nqkoi drug pyk si markira
peering paketite sys syshtiq TOS, seti se kvo she stane kato ti vlezat v mrezhata
:)))

ipchains -A output -i eth0 -p tcp -d 0/0 -t 0x01 0x10

taka mai e po-malko pisaneto :)))

A i malko me symnqva tvoqta komanda po-gore da proraboti ;-)
