L2TP from Customers to AAISP

There are two reasons to use L2TP to connect in to AAISP:

  1. As a back up for your existing AAISP circuit in the even of a fault, using L2TP you can use another ISP to connect in to AAISP and have your normal IP addresses etc whilst your AAISP connection is fixed. Ask staff to set this up.
  2. Connect in to AAISP over a third-party internet connection. This gives you your an AAISP IPv4 address and an IPv6 block. There are more reasons and information on [1]

Connection Details

  • Endpoint: l2tp.aa.net.uk
  • Username & Password as supplied
  • Hostname: AAISP
  • Plain L2TP without any IPsec, MSCHAPv2 authentication

MTU

You may have to set a lower MTU to accommodate the host ISP, possible as low as 1462 (or lower for some ISPs). In theory fragments will work to allow 1500 MTU on our service, but fragments are inefficient, and if everyone sends fragmented packets that could degrade the service.
