Hi all
Firstly I've been playing with Cisco and Windoz for over 10 years and thought I knew a thing or two about networking. Recently I replaced all my Windoz machines with Apple OS X 10.6. Unfortunately for me none of my knowledge to date is on OS X and has proved to be none transferable.
The Problem:
I want to be able run Bonjour between subnets, separated by a routed core, to provide printer sharing.
I've read that Bonjour uses the Multicast group 224.0.0.251 on UDP port 5353. So I tried to 'ip forward-protocol udp 5353' but this did not work. I also tried 'ip directed-broadcast' with an ACL to match 224.0.0.251 and this did not work either. Then I remembered that addresses in the 224/8 range are specified as link local and should therefore have a TTL of 1 so routing between domains won't be possible?? Right??
So, I moved on to explore Wide-Area Bonjour with mDNS and found that this also uses the same 224.0.0.251:5353 address. I don't understand how this work or can I get it to work. I'm not sure I understand what is needed in the SVR DNS records.
Has anyone been able to get Bonjour services working between subnets?

It's a very long time, since you did start this discussion.
Did you get any answers?
If so, could you let me know the outcome, as I have the same problems with my SA520W.
Regards and thank you for your replay.

Hi,
I am starting to look more into this, as we have few second gen Apple TV's and would like to have our iPhones/iPads AirPlay to them. Of Course those devices are on different subnets.
I found guide:
Using Bonjour Across Subnets

I'm still in the process of reading and researching, however if someone has found a better or easier solution, or has made a simple guide. Please let me know.
Thanks
