всем привет
имею два выхода в инет
нужно сделать что бы могли входить на различные службы как на один так и 
на др. интерфейс.
ppp999(ppoe средствами etcnet) и eth888(pppoe на модеме и на нем 
настроен dmz)
[root@gate eth888]# ip a

пытаюсь промаркировать пакеты идущие на eth888
[root@gate sysconfig]# cat /etc/sysconfig/iptables.conf |grep mark
$IPTABLES -A INPUT -t mangle -p ICMP -i $EXTERNAL_IFACE -j MARK --set-mark 1

потом дабвил 201
[root@gate sysconfig]# cat /etc/iproute2/rt_tables
#
# reserved values
#
255     local
254     main
253     default
0       unspec
#
# local
#
#1      inr.ruhep
201     cts.inout

и дабавил маршрут
ip route add default via 192.168.23.1 dev eth888 table cts.inout
192.168.23.1-это IP на модеме

[root@gate eth888]# ip rule ls
0:      from all lookup local
32765:  from all fwmark 0x1 lookup cts.inout
32766:  from all lookup main
32767:  from all lookup default

[root@gate eth888]# ip r
