(RADIATOR) Some users got connected without IP in NAS.

[Nayeem]

Thanks for reply,

 

Actually we have different IP Pools for different domains like
256.domain.com or 128.domain.com or 64.domain.com that why we cannot use
Router Pool and some users had static IP also but presently we are facing
this problem very frequent. So how can we solve this issue.

 

Regards,

Nayeem.

Are you using dynamic IP pool? If yes, are you using the pool on the router
or do you let RADIATOR do the dirty deed of giving out IP-Adresses?

 

IMHO the best way is to let the router deal with the dynamic IP's.... 

 

On a CISCO router it sometimes happens that the user don't get a dynamic
IP-Address when the PPP Negotiation takes too long or the client demands an
IP Address the router is not willing to give (we had some time ago a 64k
dial in demanding our main DNS servers address... brrr :-), so client and
router couldn't agree on an address, and the connection stays LCP
up/negotiating for a bit.... in the 'show user' on a cisco it's shown as a
virtual interface without an IP..... 

 

Another possibility is, that the router runs out of dynamic IP-Adresses...
(all used), that is easyly checked by a 'sh ip local pool' ... if yes, just
add some more addresses to the pool - you can do that on the fly...)

 

If RADIATOR gives out the (dynamic) addresses, it can be that some addresses
are not stored in the database, and RADIATOR dishes out the addresses
twice... making a mess on the router... (that's why I don't like the Idea of
Radiator giving out the Addresses, makes the router more vulnerable to such
errors...)

Dear All,

Presently I'm facing problem that when ever I restart radius then some users
got connected without IP address in NAS, so what could be the reason that
users didn't get IP in NAS?

I check the trace 4 logs also but could not find this problem.

Thanks,

Regards,
Nayeem.
