Title: using my opnsense device as an Exposed Host
Post by: tre4bax on July 22, 2023, 04:35:27 pm

Up until now I have used a broadband modem connected to my WAN port using PPPOE.

PSTN telephony is being turned off so the only way to get this now is to use my providers (Vodafone) broadband.  Having just had the opnsense device die I have replaced it and have imported the setup that has been working for the last 5 years.

My plan was to connect the opnsense router (OR) to the broadband router(BR) by having the OR WAN port as an exposed device on the BR.  This connection works on the OR box where I can ping the BR routing address from the OR box but there is no routing going on.

As I changed the WAN port from PPPOE on the OR to static IP does this change all the rules and things?

Are you setting the Vodafone router to bridge mode, configuring the OPNSense as a DMZ host, or using double NAT?

I wanted to connect via the Public Subnet.  That did not work.

I'm now trying it as a DMZ host, but not wedded to this I just want to make it work

So I currently have setup the vodafone router with a Public subnet and have added my opnsense router to that subnet and I get this far.

I get all the way to the providers end of the broadband service, but it fails when I try and get to an internet site.   Which I am assuming is something to do with the vodafone router as once it gets to the Vodafone side of the Public Subnet (192.168.200.1) it is beyond the control of the opnsense router.

Any ideas how I can get past this last hurdle?

What do you mean you have the vodafone router with a public subnet?  What model is the router?

It's an option on the router I have which is a THG3000g.

No idea how old it is, only came out the box when the opensense box died as an emergency measure.

I gave up on the VOIP and went back to the PPPoE, which is working perfectly.
