Здравейте имам един проблем със сплита на 2 провайдъра
зачи мойта обстановка е такава:
# eth0 - local network ip 192.168.115.10, network
192.168.115.0/24
# eth1 - ISP1 network ip 192.168.1.2, network
192.168.1.0/24, getaway 192.168.1.1
# eth2 - ISP2 network ip 217.10.251.222, network
217.10.251.0/24, getaway 217.10.251.1
значи пускам скрипта както е от lartc.org
#!/bin/bash
route add 192.168.1.2 gw 192.168.1.1 dev eth1
ip route flush table T1
ip route flush table T2
ip route add 217.10.251.0/24 dev eth2 src 217.10.251.222
table T1
ip route add default via 217.10.251.1 table T1
ip route add 192.168.1.0/24 dev eth1 src 192.168.1.2 table
T2
ip route add default via 192.168.1.1 table T2
ip route add 217.10.251.0/24 dev eth2 src 217.10.251.222
ip route add 192.168.1.0/24 dev eth1 src 192.168.1.2
ip route add default via 217.10.251.1
#Refreshing ip rules
ip rule del from 217.10.251.222 table T1
ip rule del from 192.168.1.2 table T2
ip rule del from 192.168.1.2 table T2
ip rule add from 217.10.251.222 table T1
ip rule add from 192.168.1.2 table T2
ip route add 192.168.115.0/24 dev eth0 table T1
ip route add 192.168.1.0/24 dev eth1 table T1
ip route add 127.0.0.0/8 dev lo table T1
ip route add 192.168.115.0/24 dev eth0 table T2
ip route add 217.10.251.0/24 dev eth2 table T2
ip route add 127.0.0.0/8 dev lo table T2
и в таблиците са ми ето така:
root@ns:~# ip route show table main
192.168.1.2 via 192.168.1.1 dev eth1
217.10.251.0/24 dev eth2 proto kernel scope link src
217.10.251.222
192.168.1.0/24 dev eth1 proto kernel scope link src
192.168.1.2
192.168.115.0/24 dev eth0 proto kernel scope link src
192.168.115.10
127.0.0.0/8 dev lo scope link
default via 217.10.251.1 dev eth2
root@ns:~#
root@ns:~# ip route show table T1
217.10.251.0/24 dev eth2 scope link src 217.10.251.222
192.168.1.0/24 dev eth1 scope link
192.168.115.0/24 dev eth0 scope link
127.0.0.0/8 dev lo scope link
default via 217.10.251.1 dev eth2
root@ns:~#
root@ns:~# ip route show table T2
217.10.251.0/24 dev eth2 scope link
192.168.1.0/24 dev eth1 scope link src 192.168.1.2
192.168.115.0/24 dev eth0 scope link
127.0.0.0/8 dev lo scope link
default via 192.168.1.1 dev eth1
root@ns:~#
и в такъв случай вижте какво ми се получава
ping -I eth1 www.abv.bg
