For all of my dynamic DHCP leases the lease expire has 120 minutes.

 

For all of my static DHCP leases the lease expire has Expires : October 9, 2159 1:20:03 AM

 

Using router in standalone mode until all of the standalone features are available in the Omada Management Platform which as of this version of the firmware they are not.

 

I have seen reference to other consumer TP-Link routers having this issue of DHCP expiry times. 49710 days, 6 hours, 28 minutes, 15 seconds but related to that article, there was no solution given.

 

If you require additonal information, I can offer that to you.

 

Experienced network admin here so please ask appropriate questions.

 

Thanks.

Interesting, mine has a lease till October 16, 2159.

Maybe that is to be expected when using DHCP reservations?  

Is there any problems with having a lease expire that far in the future if you have reserved the IP address?

ain't this virtual machine IP address? LOL.

i think virtual machine would get something like this, unless you modify its NAT mode.

It is actually a Hyper-V virtual Host computer that runs virtual machines.  But a VM will act the same as a bare metal computer when it comes to IP addresses and DCHP.  They all look the same to the router.

  @jg1212 Thank you that does answer the question. Unfortunately, should that ethernet client (PC, MAC, Camera, etc) need to be placed on a different static DHCP IP in the future, you are now forced to reboot / renew the ethernet client to obtain the new static IP being assigned. Not the end of the world but good to know it was not a "bug".

It is good to know they are not breaking the RFC1541 setting for infinity but would be nice to have static DHCP IP ethernet clients to check as often as non-static DHCP ethernet clients as many other network vendors offer including TP-Link offers with other products that I have used in the past that have DHCP capabilities.
