Using a router as an ACS server


i'm having problems with one of my acs appliances - i suspects its giving out duplicate IP addresses to users and therefore causing vpns to fail

i only have 8 accounts but each one represents a department in my organisation and the departmental account is used to validate a PPP connection

each department has a dhcp scope of 62 addresses allocated from the acs server

i'd like to temporarily replace the acs server with a router to see if the problem of duplicate addresses still occurs

the current acs server uses radius packets from an upstream nas

has anyone had to use a router for this purpose and if so are you aware of any config guides?

thanks to anyone taking the time to read this or reply

greatly appreciated


Re: Using a router as an ACS server

Yes, it is recommended to use router as dhcp instead of acs. Seen many similar issue with acs dhcp.

Re: Using a router as an ACS server


many thanks for your reply

can you point me to any guides

i suspect i could use the acs for authentication and hand over to a router for dhcp allocation

i would need to run 8 separate scopes

thanks again
