No internet for dynamic DHCP assignment, internet works for static DHCP client
« on: December 30, 2018, 10:05:19 pm »
Any LAN DHCP client getting a dynamic DHCP assignment from the pool on boot will not have internet connectivity. but if I assign the MAC to a static mapping in OPNsense, Internet works.
I do not think there should be any difference (other than LAN address) between the two, but dynamic doesn't work, while a static mapping does...

I'm running 18.7.9

How do you define 'Internet works'?

Can you ping public IP addresses? Can you resolve public DNS queries? What are the differences in the IP stack between a working static and a non-working dynamic client?

Did you enable "Enable static ARP entries" in your DHCP (4?) server? Then this would be expected behavior...
