I have my ERLite-3 setup in the 1 WAN 2 LAN config at my home and use the 2nd LAN as VoIP only on a totally different subnet. However, the Dashboard is showing MASSIVE traffic between the 2 LAN's, ie 250TB in the past 2 weeks! I need to limit traffic between the two LAN's. Really, I only need to get to VoIP from LAN to make adjustments on my VoIP hardware. VoIP should NEVER make an initial connection to LAN.
My thoughts would be to setup FW rules that are similar to the WAN->LAN, but be VoIP->LAN, ie have the FW block new/invalid connections from VoIP to LAN and only allow established connections. But I can't figure out how to set that up, any help?
