Diameter Support

Hello,

Can anyone suggest me the MT version that supports Diameter protocol for AAA server..

Thanks in advance

RouterOS does not support Diameter

There is an extension to MikroTik recently published by a joint company under “Made For MikroTik” program. The name of the software is “GNAS (GoldNet AAA Server) with Diameter and Radius Protocols Support (Carrier Level implemented)”
