[chente]

Dear, thanks the author of this great software to free for the community.

I have a adsl router (huawei HG556) with IPSEC cliente integrate for doing LANtoLAN VPN.
I d like to know how to setup to connect to a ethersoft server installed in linux server. This server is able to accept embeded XP client (L2TP-IPSEC).
I attach images with router view.

I have readed that document yet , but doesnt apply for my case.
MY router has a classic IPSEC config , transport or tunnel, but authentication is with PSK .
This is the same type I see in other routers i have here, as image show.
So question remain the same:
Can my router connect with IPSEC (but not L2TP) to softether server ?
how to ? tunnel or transport mode? ESP or AH ? encription algorythm ?

thanks
