Hello,

 

Answer is in your LOG.

You have no free IPs on dhcp pool. 

Your subnet mask is 255.255.255.224, then you have just 30 usable IP addresses.

You need extend your ip pool. For example, your subnet mask can be 255.255.255.0

but in the network the client has not reached 30 ip addresses.

where can i check the usable ip address?

Hard to help without further information - how large is the DHCP network, the number of clients and what about the state of the leases - see sk120297: How to remove DHCPLeasesfrom SMB Gaia Embedded appliances on how to check that.

Without support, nothing is possible 😉 But you could try e.g. a simple

# find / -name '*dhcpd.leases*'

HI @G_W_Albrecht , thanks for your reply

when i follow your script # find / -name '*dhcpd.leases*'

this is the result :

dhcp.leases.JPG

then, what must i do ?


just delete file with rm -f dhcpd.leases.LAN3.2056 ?


or are there other steps that I have to do ?

 

thanks and regards

Yes: Delete the interface file and reboot - a new one will be created and that should resolve the issue.
