Hello,
I just setup a wireguard site-to-site connection which in general now seems to work fine. So there is a way opnsense at site A has internet access and LAN devices can also reach the other site B through the tunnel.
Unfortunately, the LAN devices at site A, which shall access the internet through opnsense at site A, seem to have no internet access besides of that. I cannot reach the web and cannot ping e.g. external IPs like 8.8.8.8. Do it's obviously not only a DNS issue. Computers at site A have OPNsense site A as default gateway.
Maybe I have mistaken or forgotten something about an interface or firewall rules (although I followed the guide). LAN interface das the default allow any rule.
Or could it be something about (outbound) NAT? I'm not familiar with this and how traffic is being passed between interfaces (I thought, the LAN firewall rule was enough).
Any help on where to start troubleshoothing appreciated.
