#1
I setup an IPSEC tunnel between 2 routers. It works fine.
#2
I setup a PPTP tunnel inside the IPSEC tunnel, it works fine.
I setup a L2TP tunnel with "use encryption=yes" inside the IPSEC tunnel, it works fine.
#3
I setup a L2TP tunnel with "use encryption=no" inside the IPSEC tunnel... it connects but won't pass any data.
I don't need encryption with L2TP because it is inside an encrypted IPSEC tunnel already.
Why does it not work when MPPE encryption is disabled?
Any ideas?
