[Openswan Users] 2.6.11+IP_MULTIPLE_TABLES+openswan=broke

[Art Mills]

I am sure this is a kernel thing but since it affects openswan and may
help sombody

just compiling it does not break it but if you use it for example

kernel 2.6.11 ( no patches )
openswan 2.4.4

linux      = 10.0.100.107
xp machine = 172.25.173.2

run the command ip route add 172.25.173.0/24 dev eth0 via 10.0.100.104
table sometable

verify the xp machine can tak to the linux box

ipsec/l2tp connection from the xp box using certificates fails
run
ip tables flush table sometable
route add -net 172.25.173.0 netmask 255.255.255.0 gw 10.0.100.104
ipsec/l2tp now works
