I have 4 interfaces as follows:
[LAN] 192.168.x.0/24
[VLAN200] 192.168.y.0/24
[VLAN300] 192.168.z.0/24
[WAN] <public ip address>
Sometimes, I have been logged in to OPNsense from my laptop on the LAN or VLAN20 network and then I lose access to OPNsense. It responds to pings, but nmap suggests no ports are open.
Now, the weird thing is that I'm able to log in again, but only from the public WAN address. This only works from my internal networks, I'm not able to access it from the public internet. Then, after a while I'm able to access it again from the LAN or VLAN20 network and nmap shows ports open again.
Grateful for any insights.
No, but thanks for suggestion. Issue has disappeared. Suspect it was issue with my laptop, not opnsense.
