i'm trying to establish L2TP tunnel.
Issues become when accessing by iPhone
MT to MT works great.
I haven't tested it by android i'll try today
Thanks SindyBecause different clients use different proposals on their end and if the proposals of the peers don't match in at least one algorithm for each purpose (authentication, encryption, initial key exchange, PFS), the connection cannot be established. So nothing on the list of auth-algorithms of your peer serving the L2TP/IPsec purpose was supported by the iPhone, while sha1 is.
