[Openswan Users] ipsec verify reports "IP forwarding failed"

[Nick Howitt]

Paul,

I reported the same thing to you sometime within the last year and you 
told me not to worry. If it of any interest, it is still happening and I 
am running ClearOS 5.1 (also CentOS based) with openswan 2.6.26.

Regards,

Nick
