There are two reasons to use L2TP to connect in to AAISP: #As a ~~back up~~backup for your existing AAISP circuit in the ~~even~~event 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.~~ #Logging in over L2TP using your DSL credentials (ie xxx@a.1) from a different ISP will give you your normal IP addresses. You can use this whilst your AAISP connection is being fixed. #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 [[http://aa.net.uk/broadband-l2tp.html]] #This is enabled by default and available to everyone, there are no extra charges. Usage is taken from your quota in the usual way as if you were connecting over DSL. #Regarding IP routing, The L2TP has priority over the DSL, so you'd want to bring it up/down as and when required as the DSL won't have IPs routed to it when the L2TP is up. #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. #There are more reasons for doing this and further information and ordering on http://aa.net.uk/broadband-l2tp.html ==Connection Details== Endpoint: * ~~Endpoint:~~ l2tp.aa.net.uk or l2tp6.aa.net.uk Username & Password as supplied * Hostname: AAISP * Authentication Protocol: CHAP/MSCHAPv2 or PAP, but recommend CHAP, as L2TP is not encrypted * Plain L2TP without any IPsec, MSCHAPv2 authentication * Plain L2TP '''without any IPsec'''. This is important as some devices may not support disabling encryption on L2TP. == Speed/Latency Tweaks == See: [[L2TP-Latency-Speed-Tweaks]] Check that your ISP/mobile provider does not have features that will block 'VPN' services - eg Vodafone's 'SecureNet' will block access to our L2TP service. ===MTU=== You may have to set a lower MTU to accommodate the host ISP, ~~possible~~possibly 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. = ~~Some~~ Notes ~~from customers~~on setting up L2TP IN to AAISP: = {{AAMenu\|img=Menu-FireBrick.svg\|link=L2TP_Client:_FireBrick\|title=L2TP from FireBrick\|text=Creating a L2TP connection from a FireBrick to AAISP)}} {{AAMenu\|img=Menu-Apple.svg\|link=L2TP_Client:_OSX\|title=L2TP from OSX\|text=Creating a L2TP connection from Apple OSX to AAISP}} {{AAMenu\|img=Menu-Windows.svg\|link=L2TP_Client:_Windows\|title=L2TP from Windows\|text=Creating a L2TP connection from Windows to AAISP}} {{AAMenu\|img=Menu-Linux.svg\|link=L2TP_Client:_Linux\|title=L2TP from Linux\|text=Creating a L2TP connection from Linux to AAISP using xl2tpd}} {{AAMenu\|img=Menu-Linux.svg\|link=Router:Linux_-_Debian_-_With_L2TP_Fallback\|title=L2TP Failover with Linux\|text=Creating a L2TP fallback for AAISP using pppd and xl2tpd}} {{AAMenu\|img=Menu-Routerboard.svg\|link=L2TP_Client:_Routerboard\|title=L2TP from Routerboard\|text=Creating a L2TP connection from Routerboard to AAISP}} {{AAMenu\|img=Menu-OpenWRT.svg\|link=L2TP_Client:_OpenWRT\|title=L2TP from OpenWRT\|text=Creating a L2TP connection from OpenWRT to AAISP}}
