Hey Ricky,
Yes that is the exact setup, the cableco bring the customer to us via
L2TP, and now want to do PPTP only.
I will keep digging on the ARRIS, which I have been told is a C4 system.
Although their website doesnt show much tech specs.
They are pushing for the L3 option since their CMTS will now be a hop in
the path between the customer and us, instead of L2 transparent.
Suggestions?
Thanks,
