Dear Friends, I would like to know detail on proxy implementation. *Currently:* NAS ----> Radius stack (1812,1813). *new proxy approach: * NAS -----> Proxy Radius ------> Radius stack1 (1822,1823). 1st change: Proxy radius implementation with one home servers (stack1 ). 2nd change: Changing current radius stack to run on 1822 (auth) and 1825 (acct). What are all configuration change that I have to do for 1st change and 2nd change. As per my knowledge, *1st change includes:* 1) install new freeradius and configure to accept traffic from NAS. 2) configure proxy.conf to send auth and acct request to home server (stack1). *2nd change includes: * only change the etc/raddb/sites-enabled/inner-tunnel change it as below *listen {* * ipaddr = 127.0.0.1* * port = 18220* * type = auth* *}* Please let me know if any other configuration change that I am missing in the step 1 and 2. -- Regards, Srithar Durairaj Alternate Mail I.D: srijeevadurai1@yahoo.co.in Mobile: +919886251852
