Using Calling-Station-Id or AcctSessionId as NAS-Port

[Toledo, Luis Carlos]

I need to use Calling-Station-Id (or AcctSessionId) as NAS-Port and provide
dynamic Ips using rlm_ippool.

Using attr_rewrite it´s possible to make this change (Calling-Station-Id =>
NAS-Port), but the freeradius/modules C code define port as int. My
calling-station-id have 15 numerics chars of size.

Have anyone any idea ?

Thanks
