DHCP cannot access internet

Clients are getting ip from DHCP Scope but for some clients they
cannot access internet even they cannot ping to any public ip in my
network, this problem continues for around 20 hrs and after that they
can access internet.

I gave them static ip outof my dhcp scope then its works instantly.

what could be the problem, anyone can help

Hello (E-Mail Removed),

Ping problem, Firewall. Please post the scope options you provide to your
clients. Also describe how you have setup DNS.

Best regards
