Hello all:
Site A: my home
OPNsense Firewall (192.168.1.1)
Wireguard S2S active (to site B)
Site B: my club
OPNsense Firewall (10.0.1.1)
Wireguard S2S active (to site A)
I have setup a Zabbix server on Site A. I have setup a Zabbix proxy on the Site B firewall, using the Zabbix proxy plugin. I can successfully run a port probe from Site B to Site A, using TCP port 10051, which is the Zabbix port needed for communications. When doing the same thing from Site A to Site B it fails. I have attached screenshots to show the successful and failed port probe.
I am confused as to why it works one way and does not work the opposite way. I would think that since its open in one direction it should be open in the opposite direction? Am I missing something here?
Thanks,
Steve
