possible dhcp bug

[rew1ndustry]

CMD>show dhcp
DHCP table:
50:02:91:df:3d:04 - 192.168.10.2 - 119
b8:f6:b1:19:58:57 - 192.168.10.4 - 99846

the second device, on dot 4, has been out of range since yesterday, but this timeout will take years to count down, and is persistent even across reboots.

Did you save your DHCP table (save dhcp at telnet prompt) while the device 192.168.10.4 was connected? ESP comes up with lease time 100000 after reboot if you saved it ...
If a device connects, the lease time gets set to 120.

BTW, I plan to open a PR to make the lease time changeable, as 2h is too short for my application (the device is offline during night). So it always gets a new IP and not the same. This is bad if you like to use the portmap feature.
