isakmpd enc0

["dkwok_(_at_)_iware_(_dot_)_com_(_dot_)_au" <dkwok_(_at_)_iware_(_dot_)_com_(_dot_)_au>]

I have got the x509 certficate exchange ok. From checking the netstat  I 
can see the ipsec in force.

However I cannot ping the other end. Then I read something about letting 
lose the enc0 in the firewall.

I have done that accordingly and it works. Man enc0 does not reveal 
anything what enc0 is doing. Could someone point me to reading about 
this device?
