Hello, - within radsecproxy.conf you can add simple rewrite rules with "addVendorAttribute <vendor>:<attribute>:<value>" with all numerical values just like with the other attribute configuration options. e.g.: rewrite miktest { addVendorAttribute 14988:27:2000 addVendorAttribute 14988:26:0 } - When I radtest with a client, I get: Received Access-Accept : Mikrotik_Wireless_VLANIDtype = 842018864 Attr-26.14988.26 = 0x30 => So, the number 2000 is transformed into 842018864 and 0 is transformed into 0x30. => My question is: Why is it transformed and how can I stop this? Looking at /usr/share/freeradius/dictionary.mikrotik: ATTRIBUTE Mikrotik_Wireless_VLANID 26 integer ATTRIBUTE Mikrotik_Wireless_VLANIDtype 27 integer If would be great if someone could give some hints Regards Michael
