I am running SBR Carrier and am configuring roaming share with a partner. I have configured normal proxy forwarding and have no problem with that, but they have now come back stating that they will require "prefix routing"... So, the format of the NAI is as follows:
So, they need the prefix "example" stripping and being read along with the "realm (iamhere.com)"
I configured the realm in the proxy.ini and have also created the .pro file for the realm. I have also created the profile and the proxy targets on the carrier SBR. But I am now stuck as to how to resolve gettting the prefix stripped and read.
As this is TTLS, the SBR has to be able to note the prefix and username so the "/" is the delimiter...
Will "example" always be your prefix? If it is expected to be different, you would need to add additional entries in your Realms configuration. Or, if you expect something similar to "example" you can use a wild card.
As for your Proxy Realm name. Yes, you are correct, however,since you have defined the Realm as "iamhere.com" it would be iamhere.com.pro. You need to ensure that the defined names in your proxy.ini Realms configuration are the same as the defined Proxy Realm files.
Do you expect to have filters on these RADIUS packets to your Proxy Target or received from the Target and back to your NAS? These are not required, only if you expect to add or change RADIUS Attributes.
The easiest way to create filters is through your SBR Web GUI. This will allow you to create the filters quickly and copy those filters to create additional ones.
The last inquiry, the "example" is read as a prefix as you ahve defined in proxy.ini.
