Re: Security test of firewall dose not show UDP port 500 is open

[Daniel Lucq <daniel () scanit be>]

Well, could be that the IKE service (if it is enabled) only responds to 
IKE handshake requests containing a supported IKE transform (or vendor 
ID, authentication type, etc.).

I would suggest using ike-scan to poke a bit at the target with 
different transforms etc.

Daniel
