[Openswan Users] Problem nat traversal

[Cristhian Nunez]

I did your recomendations and i still have the problem. The firewall is 
working well. For test, i disabled it and the problem continued.
it looks like this now

version 2.0
config setup
plutodebug="control parsing"
nat_traversal=yes
nhelpers=0

conn     casa-onemax
         left=192.168.1.40
         leftid=1.2.3.4
         leftnexthop=192.168.1.100 (internal default gw)
         leftsubnet=192.168.1.0/24
         leftrsasigkey=....nh7NasAXjnYDe7i/HgSnWe+P4nF
         right=5.6.7.8
         rightnexthop=8.7.6.5 (default gw)
         rightsubnet=172.18.0.0/21
         rightrsasigkey=....f8HSmVcdtGkaoSxaxLFxPx8OeJT
         auto=add

And the same error

packet from 1.2.3.4:500: initial
Main Mode message received on 5.6.7.8:500 but no connection has been
authorized

It seems that the conection 5.6.7.8 receive the package but it doesnt 
know what to do.

thanks in advance,

Cris
