Everything went smooth until I couldn&#8217;t get auto-discovery to work over VLANS. Started troubleshooting everything I could think of on PFSense thinking it was possibly a VLAN misconfiguration even though it&#8217;s worked smoothly for all other protocols &amp; services on my network in the past. With enough googling I found that it could be an issue with multicast because PFSense by default only utilizes it on the same network for good reasons. I knew the functionality over VLANS was available with the NDI software so I didn&#8217;t want to take the easy way out of putting my gaming machine back onto my default VLAN where my streaming server sits risking performance &amp; security issues. So if you want to stream or record over NDI with machines on separate VLANS or subnets, you can utilize IGMP Proxy on PFSense as I will break-down below. This is what I love about starting new projects. I get to learn as I build while adding new tools to my go-to list. IGMP Proxy was a saving grace in this situation so I hope this article helps you with your NDI struggles.<\/p>\n\n\n\n<figure class=\"wp-block-image alignwide size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"458\" src=\"https:\/\/lab2prod.net\/wp-content\/uploads\/2026\/01\/igmp-1024x458.png\" alt=\"\" class=\"wp-image-468\" srcset=\"https:\/\/lab2prod.net\/wp-content\/uploads\/2026\/01\/igmp-1024x458.png 1024w, https:\/\/lab2prod.net\/wp-content\/uploads\/2026\/01\/igmp-300x134.png 300w, https:\/\/lab2prod.net\/wp-content\/uploads\/2026\/01\/igmp-768x344.png 768w, https:\/\/lab2prod.net\/wp-content\/uploads\/2026\/01\/igmp.png 1218w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">IGMP Proxy Settings<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image alignwide size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/lab2prod.net\/wp-content\/uploads\/2026\/01\/igmpedit-1024x576.png\" alt=\"\" class=\"wp-image-469\" srcset=\"https:\/\/lab2prod.net\/wp-content\/uploads\/2026\/01\/igmpedit-1024x576.png 1024w, https:\/\/lab2prod.net\/wp-content\/uploads\/2026\/01\/igmpedit-300x169.png 300w, https:\/\/lab2prod.net\/wp-content\/uploads\/2026\/01\/igmpedit-768x432.png 768w, https:\/\/lab2prod.net\/wp-content\/uploads\/2026\/01\/igmpedit.png 1219w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">IGMP Edit Tab<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The other night I was attempting to setup OBS over NDI up again.
