ipsec encryption
 

i installed FreeS/Wan, i created ipsec.conf but when i run ipsec verify i get

Opportunisctic Encryption DNS checks:
Looking for TXT in forward map: linux1 [missing]
Does the machine have al least one non-private address? [ok]
Looking for TXT in reverse map: [missing]

i would like to use opportunisctic encryption but i dont know how to implement it or configure it.

Can anyone help me, thanks.

Well, I'm no FreeS/WAN expert, but that looks something IP/DNS related. What is your network configuration like?
