Dnes jsem se konecne dostal k source routingu. Nejdriv jsem dostal po icq radu od LOC:<\/p>\n
— a pak source routing zprovoznis pomoci tehle sekvence prikazu. <\/p>\n ip rule add fwmark 1 table nax iptables -A PREROUTING -i wlanY -t mangle -j MARK –set-mark 1 wlanY je lokalni pokryti, wlanX je spoj s dalsim AP, eth0 je k tobe do vnitrni site. Snad to bude fachat. Jenze zacaly drsny problemy. Jen jsem tam dal tu routu tak se prestal ozyvat. Ruznymi pokusy jsem zjistil, ze to hned od zacatku zacne tu tabulku brat jako smerodatnou. No nakonec jsem to vyresil pridanim radku kde explicitne rikam default routu pro vnitrni rozsah site a bylo vymalovano. Jenze pak zase nechodily routy do czfreeho \ud83d\ude41<\/p>\n # Smazne vsechno v tabulce upc Nicmene kdyz jsem pak nakonec po kompilaci jadra s s podporou flagu dal: Moc hezky, co rikate? Na tohle jsme nakonec nasel lek v podobe grepu Documentation adresare ze zdrojaku kernelu a zjistil jsem ze jsem nezaskrtl Packet mangle optionu v IP filteru.
