Zdraveite linuks maniatsi :) imam 2 dostavchika ediniia mi e btk
 adsl i drug. Imam i 20-30 klienta vurzani kum men. Imam 2
 rutera i 1 survur za klientite. 1-viia ruter mi e na ediniia
dostavchik ip adres 82.82.82.2 gw 82.82.82.1
2-riia ruter mi e adsl-a na btk 192.168.1.2 gw 192.168.1.1 
Klientskiia survur mi e s ip adres 
eth0 82.82.82.3 gw 82.82.82.1 
eth0:1 192.168.0.129
 Vruzkata kum moia survur s klientite mi e pppoe. Kogato se
 lognat kum men survara im dava adres ( 10.10.10.X ) koito se
natva kum realen adres.
 Klientite osnovno polzvat interneta na 1-viia mi dostavchik (
82.82.82.2 )
 Ponezhe imam veche adsl iskam kogato se lognat klientite
 vsichki zaiavki kum 80 port da izlizat prez adsl-a na btk. A
 vsichki ostanali ( torrenti kazzi i takiva podobni ) da si
izlizat prez 1-viia dostavchik
Vsichki survuri sa na Fedora 4

Mislia che purvo shte imash problemi s tazi fedora.
 Az sum sus skackware 10.2 i s kompilnato iadro... load
balancing i niamam nikakvi problemi.

 # To tunnel outgoing http packets and continue traversing
the rules :
   iptables -A POSTROUTING -t mangle -p tcp --dport 80 -j
ROUTE --oif tunl1 --continue
 
   # To forward all ssh packets to gateway w.x.y.z, and
continue traversing
  # the rules :
   iptables -A POSTROUTING -t mangle -p tcp --dport 22 -j
ROUTE --gw w.x.y.z --continue

predpolagam che shte se nalozhi da pachvam iptables za -j ROUTE 
 a load balancing ne mi vurshi rabota. Iskam samo 80 port da
rutiram

Mozhe sushto i da probvash s markirane na paketite

neshto ot sorta na:
 iptables -A PREROUTING -i eth0 -t mangle -p tcp --dport 80
-j MARK --set-mark 2
ip rule add fwmark 2 table http
 ip route add via 192.168.0.2 ( tova e ip-to na adsl-a ) dev
eth0 table http

2 varianta ti predlagam
 ili slagash po oshte edna lan-karta na 2-ta rutera i hi
 svyrzvash edin s drug ili slagash data internet dostavchika
na ediniq ruter, koito trqbva da e s 3 mrejovi karti.
sled tova reshenieto e sravnitelno prosto:
pravish paralelno rutirane za vtoriq realen adres:
dobavqsh reda
100 second_net
vyv faila /etc/iproute2/rt_tables nai-dolu
 (priemame che mashinata e nastroena da raboti prez BTK, t.e.
default GW e tozi na BTK)
sled tova pishesh:
#ip rule add from 82.82.82.2 table second_net
 tova pravi taka, che vsichki zaqvki ot tozi adres da otivat
vyv vtorata rutirashta tablica, koqto v momenta e prazna.
zapochvash da q pylnish:
//lokalnata mreja za klientite ti
#ip route add 192.168.0.0/24 dev eth0 table second_net
//realnata mreja ot kym ediniq dostavchik
#ip route add 82.82.82.0/24 dev eth1 table second_net
//default gw za isp-to v tazo rutirashta tablica
#ip route add default via 82.82.82.1 table second_net
sled tova si pravish nat nakoito si poiskash realen adres
a port 80 mojesh da go natnesh kym drugiq
 #iptables -t nat -A POSTROUTING -p tcp --dport 80 -j SNAT
--to 82.82.82.2

 Abe mai dosta obyrkano stana no... kakto i da e :) dano si
haresash neshto :)

"#iptables -t nat -A POSTROUTING -p tcp --dport 80 -j SNAT
 --to 82.82.82.2" po tozi nachin go natvam kum dostavchika mi s
 realni adresi a na men tselta mi e 80 port da izliza samo
 prez btk :) no ima ideia v tvoia post mislia che skoro shte uspia
da go napravia

 Ami obryrni go obratnoto, nqma znachenie koi shte e primary
:) Rezultata e edin i sysht.
