I need a small dual-WAN router to interface with an ISP for VOIP.
It needs to provide VLAN100 tagged on the LAN side (some older routers like RV042 won't do this).
It needs to have some ports opened - not forwarded, opened. (some newer routers won't do this).
I'd rather have a 4-5 port router as ports are unimportant here.
I'd like to add a management port/VLAN and block internet access from that port's connection.
What might you recommend?
