Sharing broadband with my neighbour

Installing and Using OpenWrt
1

Hi,

First ever install of openwrt (on a raspberry pi4 that had spare)

I've done a simple setup where the pi "wan" gets a ip of my neighbours router 192.168.1.x and "lan" connects directly to the wan port on my router, which then gets its wan ip from openwrt via dhcp

As i host services I've....

  1. added the openwrt wifi IP as the DMZ in my neighbours router and set router to always dish out the same IP to openwrt

  2. set the following port forwarding "DMZ" rule ..

match: incoming ip4 from WAN to device
actions: forward to LAN IP: 192.168.16.54 (ip assigned to the wan port of my home router by openwrt)

  1. set the following general firewall settings...

Everything works really well, but after about 24 hours my services running at home stop being accessible from the internet

Everything else works well, internet my end is stable and fast, getting the full 80Mbps down 20Mbps up on speedtests

Any ideas why this would be please?

Is there a better, i.e simpler solution?

Thanks

Check guide of "guest wifi" , basically other LAN without admin or main network access.

Hi,

Unfortunantly I need to use my own router (its a pfsense router with loads of config on it)

Obviosly this is not pfsense helpdesk.

oh my question is nothing to do with pfsense

ah just discovered this ...... https://openwrt.org/docs/guide-user/network/wifi/relay_configuration

.... openwrt as "a transparent wifi bridge"... my wan port of my pfsense should then get a ip directly from my neighbours router and i can then set that as the DMZ ip in my neighbours router

(no more double NAT'ing)

I like openwrt, just its a totally different methodology compared to pfsense, but for a lot of scenarious its def the superior solution :slight_smile:

What is the actual purpose of the OpenWRT device? Why not just go directly from neighbour's router to your pfsense router?

no possibility of running a cable unfortunantly
