A viewer asked me to do a quick video for him, on how to bridge the extra ports you have in your firewall, I too had problems with this. In this video i show you actually how easy it is !

Questions ? jason @ jasonslab . ca

  1. Captive Portal Customize Vouchers System

    My clients are facing difficulties when trying to log in using the vouchers I provide. The current voucher format is somewhat complicated for them. Here's the current format as an example:

    Voucher Format:

    Username: Gj54b#

    Password: v&Td4s

    I'm interested in simplifying this format, perhaps by using just a voucher number or even by combining the username and password into a single numeric code. Is it feasible to use only numeric codes for authentication? Your input on this matter would be greatly appreciated.

  2. Thanks – I'm close I think – I tried this from a fresh install after I worked out how to get internet working but only via 1 of the LAN ports on my router (mini pc). My PC has 3 ethernet ports but when I plug my PC into the other port in your step @5:50 I just loose connection and even swapping the cable into the next port doesn't sovle it. I have to be close but are there other ideas? Does this guide assume I've setup other aspects of the configuration? At the moment I have static IP on the LAN and that's about it which gives me internet to one computer :/

  3. My brain is spinning backwards and sideways trying to understand why, not only it didn't work on my end, but why did it make me lose internet on the one interface that was working…

  4. Thank you for the tutorial! Curious as to why bridging is not recommended on various channels and forums? Supposedly there is a performance penalty, if so how much? What would be the recommended alternative if you want to utilize the additional ports on the same local network? Btw, I am using unmanaged switches.

  5. Thanks for the tutorial. You may also need to configure the firewall rules for each bridged ports if you have multiple subnets & existing firewall policies. You might also be able to keep the port assignments to the default if you copy all the fw rules, dhcp, etc rules to the bridge interface.

  6. Hey Jason. Thank you very much! Brand new subscriber here. I would like to share that after I successfully followed your steps on this video, I realized I could not reach or ping any IP directly in my LAN. No DCHP leases for any other device on a switch etc. So I found out that in order to get the bridge fully working for Firewall Rules, we need to disable filtering for the Bridge members interfaces and enable it for the Bridge interface itself: System ‣ Settings ‣ Tunables and change "net.link.bridge.pfil_member" to 0 and "net.link.bridge.pfil_bridge" to 1 (inverting the default setting). Hope it helps!

  7. Brilliantly explained Jason, well done. I've been head scratching for days now trying this. I'm swapping an OpenWRT 3200 with VLANS's out for this as I now want to compare performance, so want to mirror the setups. My OPNsense box is an APU4. Nice box, just remember to get the correct OPNsense image for installation, and it works MUCH better during installation if you use putty than console on Linux.

    I previously had it all working but as the setup is so stable, I forgot how I set up the OPNsense box last time! [write the fine manual this time 😉 ]

  8. Very informative. Do you have also a video about firewall rules and DNS override? Something that dives a bit deeper into them. I had some problems at set them up properly. Thanks
