[RADIATOR] Limiting the number of Radsec connections

[Stefan Paetow]

Hi all,

I have a situation where I run a server with a large farm size, but I am trying to keep the number of outgoing Radsec connections low. To my knowledge, if I have a farm size of 64, all 64 of those farm threads will eventually create a connection to the other server.

FreeRADIUS sets a limit of 16 threads and connections per client (per IP), and outgoing traffic seems to be handled by a single thread there. Radsecproxy is similar in behaviour to FreeRADIUS. We’d prefer not to have to ask the site in question to up their pool size in FreeRADIUS but rather limit our number of threads dealing with outgoing Radsec.

I suppose this would mean either:
- A hidden feature (is there one)
- Running a separate farm (of let’s say 8) that deals only with outgoing Radsec, and having to fiddle our config to tell our 64-size farm to connect internally to the farm of 8 to deal with the traffic.

Is there any way around that? If not, is the latter what I would need to do? And is this something I should be able to do without complicated port assignments?

With kind regards
