1:1 NAT rule (w/ VIP) breaks connectivity to WAN
0%
Description
Clean installation on a computer, setup default gateway, dhcp and set up basic internet connectivity, no packages, nothing.
VM (or computer) internal IP: 192.168.10.18
External IP: 50.242.64.21
VIP gets created (50.242.64.21/32)
VM (linux, or computer, windows) can still connect to WAN
1:1 NAT rule gets created to map external IP to internal IP, WAN connection is broken. Internal communication still works. If there's a diagnostic or somesuch I can provide, let me know.
VIP Rule screenshot and 1:1 NAT rule screenshot attached.
No floating firewall rules, I can setup this machine on another IP and give someone a login if they want to take a look as well.
This works fine on a ALIX board I have, but I installed pfsense on an old gateway machine with a realtek NIC and a separate Intel NIC I got and it doesn't seem to work.
Version: 2.1-RELEASE (i386)

To note: I've tried taking the backup from the alix board and applying it to the new machine (intel motherboard), and this also does not work.

1:1 NAT works fine, sounds like you have an issue with your upstream ARP cache.
