RE: lug-bg: ARP

[bkrosnov@xxxxxxxx (Boyan Krosnov)]

Ne mojesh da ochakwash che kato imash pripokriwashti se adresi na
interface-ite pri towa s edni i syshti maski shte mogat da se route-wat
paketi kym syotwetniq subnet.

Problema ide ot towa che w routing tablicata imash dwa route-a kym
syshtiq segment i kernela wzima pyrwiq ot dwata.
Mojesh primerno da addnesh host route-owe kym wsqka ot mashinite
zakacheni w mrejata na wtorata karta. Taka kernela shte otkriwa host
route-owete kogato destination ip-to e nqkoj ot opisanie hostowe i
subnet route-a kogato ne e. I da punesh proxy-arp za da moje da ti
raboti routinga s drugata mreja.
Towa razbira se hich ne e preporychitelno da se prawi.

Iskash da sa ot edin i syshti subnet dwete mreji mojesh da pusnesh
bridging m/u dwata interface-a.
Razgledaj bridging howto-to.

Ako iskash da rutirash gi naprawi w razlichni subneti.

BR,
Boyan
