[New Feature - 5.7.1] Proxy Server client for AFC connection

Affected platforms: FCC locked 6 GHz AX platform
Affected versions: 5.7.1 and above

The new firmware release introduces support for a proxy server client to connect to the AFC server. The proxy server client is available for AP/SM radio mode and for all diver modes (ePTP, WLR, TDD). The feature comes to resolve AFC server access issues when ISP infrastructure management is exempt from Internet access.

The proxy server client can be configured using all standard ePMP configuration methods.

Is there an ETA for release of 5.7.1, or of a beta to test this functionality?

It’s coming in a couple days. Probably tomorrow.

Hi Fedor, this feature AFC is only available in USA? at least i see this in the LinkPlanner online. Should be available for ROW in a future? thanks!

When will the proxy server software be available?

AFC is only for radios set to FCC right now. So to use a ROW radio with AFC you have to set the country to USA. However if your country participates in the AFC system (currently USA and Canada) then the GPS coordinates will give you access to the correct system settings for your country, example is the extra unii band for canada.


I believe any HTTP proxy that supports the CONNECT method (such as Squid) should work.


5.7.1-RC9 (a beta release) has been released today.



Is there support for proxy authentication?

No, I’m afraid not, sorry.

could proxy authentication be added in future versions?

Hello @Arakasi,

could you tell me more about your use case? This feature was implemented for ISPs where equipment management networks have no connection to Internet. So everything happens internally.

Our use-case is for our SMs with private IPs to be able to reach the AFC over the internet.

We already have a proxy server setup that is used for this same purpose for Cambium CBRS, and we use the http://user:pass@proxyIP:port format. We require authentication so that it doesn’t get abused by people trying to use an open proxy, as it’s on a public IP (we use this proxy for multiple things, and do not want to try and just use an acl for our SM IP ranges).
