I have a very strange problem. DHCP requests (to my router, going through my PowerConnect switch) take 35 - 40 seconds.
Here is my setup:
Router (pfSense) --> PowerConnect 2824 switch --> LAN
DHCP server is disabled on the PowerConnect 2824 but is enabled on my router. However, any requests on my LAN take 30 - 40 seconds to receive a DHCP response.
I've tried a different switch (Netgear Prosafe) and it works perfectly and I receive an instant DHCP response so I know the problem is not with my router.
Can anybody please help me out?
