[strongSwan] Unable to establish SA

[Glen Huang]

Hi,

I'm trying to establish a ikev1 transport SA, but it failed with error like "received netlink error: Function not implemented (89)", I guess it might be that some algo module or kernel module is missing?

output of lsmod

I have googled as hard as I can't, but didn't find any thing useful. I tried kernel-libipsec, but unfortunately it doesn't support transport mode. So I'm at my wits end. Could some one help me identify the missing part? 

Thanks in advance.
