ACS handing out duplicate addresses

[mulhollandm]

folks

we have an acs server which manages a number of dsl terminations

three of the vpns are having trouble logging on and the when looking at the acs box for the problem vpns it seems to be handing out duplicate IPs and those handed out are only from the higher end of a 24bit mask, i.e. 172.17.10.250 - 254

has anyone seen this before?

thanks to anyone taking the time to reply

Hi,

We must configure the accounting for the users who are fetching IP address from the ACS server, otherwise ACS would never know when that user logged in or logged out and according to that IP address would be freed or assigned to the user.

many thanks for your reply

we're seeing stop packets in the radius accounting ok

we'll puruse it with the isp to make sure they're sending stop packets for all the vpns

thanks again
