I have an Issue where my OPNsense host cannot ping any Upstream Server (Router / Gateway, 1.1.1.1, ...).
OPNsense is able to ping other devices in the LAN, devices attached to the firewall are able to ping any hosts even Upstream.
When pinging from the OPNsense console I get the following error: host is down (which is obviously false: 1.1.1.1 and 8.8.8.8 should be up), surprisingly this only happens when pinging IPv4 and not IPv6. My Upstream Router is a Fritzbox which port forwards to OPNsense, for context
Fritzbox is on 192.168.1.1 and OPNsense is on 192.168.1.37.
Due to this issue I am unable to update etc. to the newest version. OPNsense IS able to ping hostnames like google.com, cloudflare.com (even curl'ing). When unplugging the connection to the router from the firewall and instead plugging it into my laptop I AM able to ping my Router (etc.).
The Gateway is listed in the ARP Table snd there is a default route...
So it seems to be an Issue with IPv4, but I am not in a position to do a factory reset.
This is all I got after a few days of trial and error, I am hoping that someone knows a fix for this...
Does anyone have an idea what the root problem might be and how to fix it?
Really appreciate it, thanks in advance!
