Hi,
we have setup a 19.1.9 vmware OPNsense appliance to regulate internet traffic. since we have a few internal hosts that need to be exposed to the internet, we wanted to use some Virtual IP's and Port forwarding to the LAN.
Although we have used this int he past , today there is no way of getting it to work.
Outbound NAT is ok (manual setup) , inbound NAT works partially - that is, the packets reach my internal hosts. I used Wireshark on the internal hosts to monitor the traffic arriving and leaving. When the host answers , the packets get bounced at the LAN interface of OPNsense. The OPNsense logs give no clue, ie. they do not even mention the arrival of the returned packets.
I've read there are some issues with VIP's and so, but that should not cause this problem, right ?
