I want to create a VPN connection between the 2 subnets using this
machine.<br>
<br>
conn ggh-gghdev<br>
# Left Security gateway, subnet behind it, next hop toward right<br>

Now, before I spend too much time troubleshooting this, is the above
scenario possible/doable ? The VPN connection spans the same machine
as both left and right albeit between different subnets.<br>
