Hi All,
I am using openswan-2.6.33 on embedded linux with powerpc processor.
My network is setup as follows
eth0 sat0 sat0 eth0
10.174.101.172/24 ----- 10.174.101.171/24 - 10.0.1.171 -------- sat connection --- 10.0.1.181 - 10.174.102.181/214 -------- 10.174.102.182/24
(lan) ( gateway A running opensan) ( gateway B running opensan) (lan)
I was able to establish the tunnel between the gateway A nd gateway B. But the packets are not encapsulated for both host-to-host and net-to-net.
Did I misss anything in my ipsec.conf file?
