slack90 3 NICa (dve ISPa edno dinami4no i edno stati4no IP
ot tia ISPta :)) tretia lan vutre6na mreja 
 kak da obedinia dvete ISPta i da MASQUERADE ma6inite ot
vutre6nata mreja 
 ideiata mi e dori da spre edinia net vinagi da ima vruzka
 kato minava prez drugia (a kogato sa i dvata na linia
 trafika da mine ot kadeto i da e ili da go obedini) iz4etoh
 go mai cialoto Adv-Routing-HOWTO no primerite sa ili za dve
ISPta s dinamic IP ili obratno . . . samo stati4ni IPta 
nadiavam se da e vazmojna tazi operacia :)
 a zabra ne sam polzval no me pritesniava "Zebra runs on
GNU/Linux 2.0.X and 2.2.X" hmmmmmmm 
ako moje primeri 10x predvaritelno 

 Samo shte kaja, 4e ima edni BGP tablici, koito dostavchicite
 ne gi puskat kym domashnite potrebiteli/clienti. Ti takyv li
si?

Az lichno bih go napravil s nqkakyv script.

OKi de moje i script no ne iskam da e ot vida 
 ping ISP1 i ako nema net route del na tva ISP1 i /sbin/route
add default gw (IP gw na ISP2) metric 1
ISP1=eth0
ISP2=eth1
v mom msakiraneto mi e 
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
posle v toia script triabva i tva da smeniavam 
 misleh si vazmojno li e da vdigna vtori loopback s
IP=192.168.0.1 kato posle maskiraneto mi 6te izglejda taka 
iptables -t nat -A POSTROUTING -o lo2 -j MASQUERADE
no kak da nakaram lo2 da e = eth0+eth1 ?!?!?!
ako e vazmojno edin primeren script . . . mai se povtariam 

ne sam doma6en potrebitel :)

. . . nema li hora koito sa pravili podobno ne6to ?!?!?!

trqbva da si pusne6 zebrata za da routira a za scripta
eto ti edin za routirane

#!/bin/sh

echo

 IPADR=$(ifconfig|gawk '/inet/{print $2}'|gawk -F : '//{print
$2}' |grep ip na dostav4ika)

route add default gw $IPADR
HN=$(hostname)

echo $HN gets IP $IPADR and routes it as Default GateWay
