A quick check of the user manual for the RV042 didn't reveal in crystal clarity whether the RV042 will tunnel multicast packets (between two RV042s).
What I'd like to create is a VPN between two different offices. Some of the applications use multicast, and it's crucial that these apps 'see' each other in both offices (via VPN).
The RV042 manual does mention a "multicast pass through" setting, but it didn't mention whether enabling this applies to a VPN connection established between the two offices, such that any multicast packet on LAN #1 is reflected to LAN #2 (and vice versa) through the VPN.
Has anyone used RV042s to create a VPN between to locations/offices, and turned on multicast pass through? Have you found that apps which use multicast (e.g., iChat on Mac OS X, Bonjour advertised infranet websites, etc.) have their multicast traffic properly appear on both LANs?
