Не удается настроить доступность openvpn по двум каналам одновременно

Настраиваю шлюз с двумя интернет каналами eth0 - 91.0.0.1 и ppp0 - 84.0.0.1. Внутренняя сеть eth1 - 192.168.0.0/24. На шлюзе установлен и настроен OpenVPN tun - 10.8.0.1.

Часть внутренних клиентов ходит через 1-ого провайдер, другая через 2-ого провайдера. Определение маршрута происходит через iproute2:

/etc/iproute2/rt_tables

101 isp1
102 isp2

 

#!/bin/bash

ip1=91.0.0.2
ip2=84.0.0.2
gw1=91.0.0.1
gw2=82.0.0.1
if1=eth0
if2=ppp0
t1=isp1
t2=isp2

# Default route for Tables isp1 and isp2
ip route add default via $gw1 dev $if1 table $t1
ip route add default via $gw2 dev $if2 table $t2

ip rule add from $ip1 table $t1
ip rule add from $ip2 table $t2

# VPN route for tables isp1 and isp2
ip route add 10.8.0.0/24 via 10.8.0.2 dev tun0 table $t1
ip route add 10.8.0.0/24 via 10.8.0.2 dev tun0 table $t2

# Smena default route
ip route del default
ip route add default via 91.0.0.1

# Marking packets
ip rule add fwmark 10 table $t1
ip rule add fwmark 20 table $t2

# PC to table ISP1 Table 1
ip rule add from 192.168.0.3 table $t1
ip rule add from 192.168.0.11 table $t1
ip rule add from 192.168.0.12 table $t1
ip rule add from 192.168.0.14 table $t1
ip rule add from 192.168.0.56 table $t1
ip rule add from 192.168.0.59 table $t1
ip rule add from 192.168.0.63 table $t1

# PC to table ISP2 Table 2
ip rule add from  192.168.0.10 table $t2
ip rule add from  192.168.0.15 table $t2

 

iptables:

# NAT
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

# Markarovka
iptables -t mangle -A PREROUTING -i eth0 -m state --state NEW -j CONNMARK --set-mark 0x1

Подскажите в чем может быть проблема?

Решение проблемы банально добавить в конфиг сервера опцию multihome
