[Openswan Users] Openswan IPSEC tunel established but it work from one side only

[Nick Howitt]

With ClearOS  in Webconfig > Network > Firewall > Incoming check that 
you have opened the standard service IPSec at both ends. This opens 
UDP:500 and protocols 50 and 51.

It is also worth noting for anyone following, that if you are using the 
unmanaged IPSec configuration in ClearOS it uses the old four conn setup 
(GW-GW, LAN-LAN, GW-LAN, LAN-GW).  If you want a single conn solution 
you need to use their paid-for service or configure Openswan yourself.

Nick
