I am trying to get Bonjour to work (vomit) across subnets. I think a multicast helper will work, but that seems like alot of work and I am lazy. I know you can add ports for IP helper addresses to forward, but I can't find if IP helper only works with a broadcast (255.255.255.255) or if it will also work with multi-cast broadcasts (I believe Bonjour works on 224.0.0.251)
If I can just add "ip forward-protocol udp 5353" (and others) and a helper address that would make me happy.
I've tried that and it didn't work.
Aruba wireless, C3850 switches and C6800 switches have a specific feature for it - so pretty sure its more than just a UDP helper - likely, IPs also have to be messed with at the application layer
Durn it, I have no money to do anything like that.
Yeah I saw the Bonjour server actually checks the IP to make sure it's in the same subnet, I am thinking I'll just put a box to man in the middle the server, and point everything to the default gateway, then tell the server it just has 10.0.0.0/8 as it's subnet.
If that doesn't work (and I doubt I can get it past STIGs for IA even if it does) I'll have to make a L2 cloud across my network
Maybe SNAT the traffic as it enters the subnet?
