Is there any way to define ip address what cisco device use when connect to MS IAS server. I have configured to MS IAS client and client is cisco 6509 router box and client ip is 6509 ip address(management address) Problem is that cisco uses different ip address (not routers management adress what i have configuréd to MSIAS client ip) when it start to discuss with MS IAS server. Can i tell cisco 6509 router what ip address it uses when start to change packets with MS IAS.
