How do I setup OPNSense as a router?

[agustinrojen]

Is the setup from pfsense the same with opnsense? Please help. I already have connection between modem and OPNsense. Now. From OPN sense to switch using the other LAN port. Therefore, I connected other PC devices into the switch as indicated in the atrachment picture. There is no internet access. So how do i setup my opnsense as a router? Am i gonna do bridging? Etc. Or what?

Thank you!

By default it should work, it creates all the necessary rules for complete access to internet (from LAN to WAN).

It is a very common situation with DNSSEC default settings, DNSSEC is enabled and hardened, because most ISP's DNS services don't cope well with DNSSEC, especially if hardened (so, not OPNsense fault, since it tries to be as secure as possible).
Try disabling Hardened DNSSEC at first [Services: Unbound DNS: Advanced: "Harden DNSSEC data"], and if it still doesn't work, try disabling DNSSEC completely [Services: Unbound DNS: General: "Enable DNSSEC Support"].

It is a issue that will be addressed at the next major release (v. 18.1 - in a few days), I have opened a bug report on github and developers are taking action.
