A kako hoces da radis loadbalancing ? Najlakse je recimo da podelis korisnike u dve grupe na dva linka i radis nat na oba linka...

U Mangle PREROUTING kazes: src adrese recimo 172.29.10.0/24 mark-routing link1, src addrese 172.29.20.0/24 mark-routing link2
U NAT kazes: routing-mark link1 nat-to adrese od provajedera 1, routing-mark link2 nat-to-adreses-range provajdera2
U routes kazes: mark-routing link1 to-table link1, mark-routing link2 to-table link2
U table link1 stavi kao default rutu gateway ISP1, u table link2 stavi kao default rutu gateway ISP2

//end :)

Ovakva konfiguracija nema failover i slicne stvari vec samo rutira korisnike. Prebacivanje korisnika sa jednog linka u drugi radis u mangle-u i nista vise ne menjas.

Okvirni konf:

/ ip firewall mangle
chain=prerouting src-address=172.29.10.0/24 dst-address=0.0.0.0/0 action=mark-routing new-routing-mark=link1 passthrough=no
chain=prerouting src-address=172.29.20.0/24 dst-address=0.0.0.0/0 action=mark-routing new-routing-mark=link2 passthrough=no

/ ip firewall nat
add chain=srcnat routing-mark=isp1 action=src-nat to-addresses=192.168.1.20 to-ports=0-6553 disabled=no
add chain=srcnat routing-mark=isp2 action=src-nat to-addresses=192.168.2.20 to-ports=0-65535 disabled=no

/ ip route rule
add routing-mark=isp1 action=lookup table=isp1 comment="" disabled=no
add routing-mark=isp2 action=lookup table=isp2 comment="" disabled=no

/ ip route
add dst-address=0.0.0.0/0 gateway=192.168.1.1 scope=255 target-scope=10 routing-mark=isp1 disabled=no
add dst-address=0.0.0.0/0 gateway=192.168.2.1 scope=255 target-scope=10 routing-mark=isp2 disabled=no

:)

E sad... ako hoces neki failover dzabulevodesnoperverzije moze i to da se napravi :)
Samo trebas da budes precizan sta hoces :)

Pozdrav

Pokusao sam sa ovakvom konfiguraciom ali nisam uspio :( jel imate neki kontakt da mi malo pomognete oko ovog platicu.

Hm... mora da radi ovaj konf. Proveri jos jednom da li si sve prekucao kako treba.
Vidim da mi nedostaje broj 5 u port-range za prvi ISP (65535 treba da bude).

Izmangluj tvoj IP prvo u grupu ISP1, a posle u grupu ISP2 i poshalji traceroute da vidimo gde zapinje.

Trebao bi izlaziti na internet kroz dva razlicita linka:
