New user - separate access point for WiFi

[kermitxyz]

Hello everyone!

My first post here.

Until now, I have been running two OpenWRT devices - one as main router and one as WiFi access point.  I configured the access point to use the IP of the main router as it's gateway, and all was well (main router also providing DHCP for clients)

I have now replaced the Main Internet router with OPNSense.  However, this setup no longer works.  So, I have two questions:

1. Is this by design, to stop some creating a rogue WiFi access point (makes sense)

2. What do I need to do to get this working?  (I *can* ping the AP from my desktop, but *can't* ping it from inside OPNSense - SSH session etc. and vice-versa)

I have a fairly good grasp of networking but am new to OPNSense (which I am trying as I read it is far superior to OpenWRT... perhaps that's another discussion entirely  ;)

Thanks
Richard

welcome to the forum.
It should work out of the box as long as both are in the same network. That normally means ISP > OPN > switch > AP. Sure you haven't plugged the AP into another port ?

1. No

2.
Can you ping your router gateway from your desktop, via WiFi?
Can you see the WiFi device in the Opnsense GUI, Interfaces>Diagnostics>ARP?

It is difficult to answer without some clearer knowledge of your setup, but the problem may well be something in your DHCP setup on OPNsense.

Any reason why the AP is not setup to get IP (and GW/DNS) via DHCP?

Thanks for the help all.

Re-installing OPNSense today and being a little more confident has fixed all the issues.  I'm sure I'll be along again soon with more questions as I delve deeper and try to learn more.

Cheers

While the events remain shrouded in mystery, the result is another credit to the general principle of switching it off and on again.  :)
