I'm running my VMG8324 in bridge mode as a modem for my draytek router. All works fine. I was wondering if there's any reason to have the firewall on the VMG8324 enabled since the draytek is actually doing the firewall/nat etc.. Does having the lan ports in separate interface groups completely isolate them from each other?
The reason I'm asking is that I'd like the router ip interface to have access to the draytek via the default interface group - that then enables me to setup a static route to my voip provider and use the voip ports, but this doesn't work if I have the firewall enabled. If I telnet into the router, and try and ping anything (e.g. 8.8.8.8) , I can do it if I've setup a static route for that ip via my default gateway, so long as the firewall's off. It seems like the firewall prevents router to lan traffic and I can't see a way around it, but if the 2 interface groups are completely isolated, I can't think of a reason to have the firewall running.
