Updating Multipe variables with one SQL Query

HI Matthew

I have spoken to Adrian/RevK It's something they are looking at but 
not a 'simple' change - so not something happening 'immediately'. 
Currently they set 'Chargeable-User-Identity' which is OK - and I 
could use that. The Firebrick does not hold the username (as things 
stand) once the session is setup - BUT we don't have the chargeable ID 
until the auth start hits freeradius Which means it's not available at 
the time of the IP allocation

The reason for not returning the Framed-IP they say is that the 
devices allow multiple IPs and the framed IP can be changed with a CoA 
request even - which can be nice - you can even have multiple routing 
tables - so you can have the sane IP in multiple IPs in different 
tables in a scenario like this (putting some users into walled 
gardens). Obviously in this scenario it won't change

I totally agree it is unhelpful in this case and I am not defending 
them - Just some of their thinking when I asked them- I will continue 
to nudge this one!

These are the big brother of the 2900's (the 6000s :)

This is v3 here - though happy to use / test v4 if that works for this 

Could you possibly point me at some documentation for either - Happy 
to read and test with these. I have 
which I am working through and seems sensible - but any pointers 

I'll have a read of that and see how I get on - I may come back with 
more questions

Thanks for the pointers so far
