Subject: [LARTC] FWMARK ROUTING OVER MULTIPLE ROUTERS/LANS
Date: Sun, 30 Oct 2005 11:25:21 +0000	[thread overview]
Message-ID: <200510301225.21547.bartek@go3.pl> (raw)

I would like to route ssh in my network via DSL2 and all other trafic via 
DSL1.
So far I menaged to do it for LAN2 but there are still WLAN1,LAN3 and LAN1 to 
go.
On all routers I added table "pilicka" with rule for fwmark and I fwmarked 
ssh.
# ip rule show
0:      from all lookup local
32765:  from all fwmark 0x3 lookup pilicka
32766:  from all lookup main
32767:  from all lookup default

# iptables -L -t mangle
Chain PREROUTING (policy ACCEPT)
target     prot opt source               destination
MARK       tcp  --  anywhere             anywhere            tcp spt:ssh MARK 
set 0x3
MARK       tcp  --  anywhere             anywhere            tcp dpt:ssh MARK 
set 0x3

Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

Chain POSTROUTING (policy ACCEPT)
target     prot opt source               destination

Routing for pilicka table is the same as for main table exept default gw on 
all routers.
Network is set to work with DSL1 and it is working.
