[Wylug-discuss] ipv4/6 broker and adsl supplier

[Kevin Barrass]

I cant find anything anywere showing if tunnels are allowed of Janet IP
range but it may well be that they don't, am using the BT one instead
now and it works very well it has a good tool to show you stats of
tunnel interface at BT end.

UKERNA may only allow tunnels from JANET IP addresses?
