Hosts loosing IP address

IT Asitis — Tue, 12 Mar 2019 00:36:00 GMT

hi,

I have just started to use an ASA 5510 for my network. I use the DHCP server on it and after i made the change over to ASA hosts started loosing their IP address.

This was not a problem before on my old firewall that aso had the roll of DHCP.

Is it possible that something is wrongly sett on the asa? All traffic is flowing normaly when this does not happen.

Information:

Lease length: 172800

address pool: 134 addresses

hosts: around 45 + mobile units 45

I would welcome any ideas that you have.

Hi Hilmar,

Can you post your config and topology?

Also, check the logs when PC are making DHCP requests.

Well it seems i have solved the issue.

I think all the hosts still had a lease from the old dhcp and when the new one started using its pool there where conflicts.

The following in a command promt on all hosts fixed the issue

ipconfig /release

ipconfig /renew

Thanks
