There are two reasons to use L2TP to connect in to AAISP:
# Connect in to AAISP over a third-party internet connection.
#* This gives you your an AAISP IPv4 address and an IPv6 block. This will then give you unfiltered internet access with public IP addresses etc.
#* Speed is capped at 200Mb/s (3Mb/s for the low-cost Light service).
#* There are more reasons for doing this and further information and ordering on [https://www.aa.net.uk/broadband/l2tp-service/ A&A L2TP service].
 
 
=== MTU ===
* see: [[L2TP MTU]]
You may have to set a lower MTU to accommodate the host ISP, possibly as low as 1462 (or lower for some ISPs and still lower for mobile networks). 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.
 
=== Port forwarding on some 'Mobile Broadband' routers ===
