Aaron is running udp-proxy-2020 on pfSense himself, and he's looking for help on creating a "proper package" -- I bet he'd be ok taking his work into OPNsense.  I'd love to help but I'm more like Homer in that gif.

udp proxy into vpn..... priceless.

Hi Greelan - it's funny how sleeping changes how you look at something.

When I last posted, I was thinking that marjohn56 might "add vpn support" to UBR, which "could happen" but with today's eyes, and the benefit of coffee, it's probably more likely to just ADD udp-proxy-2020 to OPNsense.

Briefly, how difficult is this to do?  Is is something a newbee could do? 
Is there a more-formal way to request new code to be converted into an OPNsense package?

THANKS Greelan!!

Hi.  I'm hoping to generate interest here, but maybe I'll start a new thread?  I'd like to thank Greelan and especially marjohn56 for their work on udp_broadcast_relay -- from here on, I'm calling it UBR to make it easier.  This is an especially useful thread >>

The goal here is to get UBR to work with vpns - in this case OpenVPN.  Yes TAP bridged connections and GRE over ipsec are available... not great, and not exciting. :-)

When I create an OPNsense interface for OpenVPN (which seems required for the UBR gui tool) -- the individual line goes white-out... which from other testing I believe means it's an illegal config.

I was surfing on UBR and VPN and found these two posts (the second is FreeBSD code) >>

Glad to help out with testing.  Hope this is an exciting topic for others!  Thanks!

I updated to 21.1.6 and it's behaving a bit differently, but still not working.

I created an interface assignment for OpenVPN (which is required for udpbroadcastrelay) and I name this assignment something unique that doesn't match the existing OpenVPN firewall rule.  I of course add another rule for the new assignment, which allows the OpenVPN traffic.

In 21.1.5, the line in udpbroadcastrelay would turn white (which I believe means it's illegal).  With 21.1.6, it doesn't go white, but with a little bit of testing, it doesn't seem to work.  I've not scoped it yet, but it does seem to be a bit closer to working.

Hi Verasense,

Sorry it's almost two months ago that you were working on this. I'm late, but looking for the same solution.  I have used udp-broadcast-relay to forward udp broadcast and multicasts across two internal vlans. This allows me to run both apps in the "other" vlan quite well! and it's all routed, no bridging.  This is perfect.

So I also want to do this for an OpenVPN client.  I've fooled around with creating some very basic firewall rules, but so far I can't seem to get it to work.  Have you had any more luck?

Thanks!
