Struggling for days on this one in a lab so thought I would send it out to see if anyone has seen this before.
Setup is as follows:
1 Modem Router no dhcp or dns on it only an internet connection, ip address of 192.168.0.1 and some wifi. It does have a firewall on it though.
ESXi 6.7 Virtual Server 2012 R2 with DHCP and DNS on it ip address 192.168.0.30. This gives out dhcp address to stuff on the network and dns on it does the dns. All sharing a physical nic that connects to port 1 of the router.
No dramas all working well for ages.
Now added a vm with pf sense on it and added a wan connected to port 2 of the lab router. Lan has a virtual nic with a 172 address and no dhcp. Still no dramas.
Then asked WAN to get its ip address via dhcp which it does. Then created a reservation as I want it to keep the same ip address all the time and thats...
