[Openswan Users] Strange ping response

[George Hadjichristofi]

Dear All,

I am trying to run Openswan userland with NETKEY.


My network is  
G1 (10.0.0.1) ------- G2(10.0.0.2)
 
My connection in the config file is:

Conn Ipv4con
	left=10.0.0.1
	right=10.0.0.2
	authby=secret
	auto=add

After I successfully initiate a connection I ping from G1 to G2.
G2 will return 2 packets, one cleartext and one encrypted.
If I ping from G2 to G1 then G1 will return two packets. 

Why does the responding gateway send 2 packets back?


Thank you,
George
