DHCP RENEW PROBLEM
0%
Description
Hello,
Since two weeks we have a problem on our DHCP Server with dhcp adress renew on our clients.
All 24 hours, clients lose IP adress and there is a network break for client.
Problem is on dhcp renew adress.
On syslog :
<191>1 2018-10-29T00:32:42+01:00 10.17.13.2 dhcpd - - - dhcpd: reuse_lease: lease age 1191 (secs) under 25% threshold, reply with unaltered, existing lease for 10.17.0.145
<190>1 2018-10-29T00:32:42+01:00 10.17.13.2 dhcpd - - - dhcpd: DHCPDISCOVER from bc:5f:f4:f7:2b:18 (Toyal-P525) via lagg0.1
<191>1 2018-10-29T00:32:42+01:00 10.17.13.2 dhcpd - - - dhcpd: ICMP Echo reply while lease 10.17.0.145 valid.
<187>1 2018-10-29T00:32:42+01:00 10.17.13.2 dhcpd - - - dhcpd: Abandoning IP address 10.17.0.145: pinged before offer
<190>1 2018-10-29T00:32:42+01:00 10.17.13.2 dhcpd - - - dhcpd: Removed reverse map on 145.0.17.10.in-addr.arpa.
But client TOYAL-P525 was 10.17.0.145 !!!!
After :
<190>1 2018-10-29T01:12:51+01:00 10.17.13.2 dhcpd - - - dhcpd: DHCPREQUEST for 10.17.0.145 from bc:5f:f4:f7:2b:18 via lagg0.1: unknown lease 10.17.0.145.
On DHCP Lease in PFSENSE:
!accous.accous.toyal-europe - Status DHCP Leases - Mozilla Firefox_2.jpg!
And client take a new ip adress :
!accous.accous.toyal-europe - Status DHCP Leases - Mozilla Firefox_3.jpg!
I don't understand why client didn't renew his adress...

This needs discussion on the forum. It's working fine for thousands and thousands of installs. If there is an issue here, it's probably not a bug in pfSense but something in your configuration, an issue upstream in ISC DHCPD, or possibly even a client issue.
