coa / proxy question

[Richard J Palmer]

OK I now have part one of this done - radacct now holds the LNS IP 
address thank you.

I just want to clarify one small thing if I may ...

With the CoA I currently have one CoA server enabled on port 3799 on 
the radius server. How should I forward the CoA to the LNS ? Do I 
setup 2 CoA servers either on different ports or IPs within FreeRadius 
and each send to a different LNS, or Can FreeRadius itself do a SQL 
query based on the AcctUniqueId and use that to get the IP to forward 
to ?

Or have I again got this totally wrong ?

Thanks in advance I do appreciate your help
