So, I've got 2 RV042's linked over a wireless bridge. I'm attempting to get a Windows Media Center 2005 system to talk with a Linksys Media Center Extender ... I can PING across the VPN, but nothing involving multicast is making it across. I don't have the config's right in front of me right now, but going from memory ... Side 1 - WAN1 - 192.168.1.102 LAN - 192.168.3.1/24 Media Center 2005 box - 192.168.3.228 Side 2 - WAN1 - 192.168.1.101 LAN - 192.168.2.1/24 Media Center Extender - 192.168.2.104 Bad ASCII network diagram: I've got all the basics enabled, RIP is diabled, and the two RV042's are setup as Routers, with the WRT54G as a gateway. My latest thought is that I need to get both ends of the VPN on the same subnet, but the RV042 doesn't appear to like being set to a /16 net (not an option in the web interface, and doing it via telnet makes the unit require a hard reboot)... So, is there a way to force multicast into the tunnel, and maybe port trigger/forward it to the MCX box? The VPN tunnel is established as a Gateway to Gateway VPN, and I can ping accross it, but nothing from the media center extender is getting accross to the media center PC. I think this might be a case of my staring at it to long, but I feel like I've tried everything. Edit: this is how fried I am, I accidentally posted this in the general networking, when I ment to put it in the RV0** section. Could a mod please move this?
