Does the BR200 support Multi-Nets NAT?
Hi, can not find an answer anywhere so I just ask here: Does the BR200 support Multi-Nets NAT ? I'm using Cisco Layer3 switch with multiple VLAN's. Most of them need internet connection served...
The BR200/500 does support multiple networks (VLAN), each with its own IP subnet, a dedicated DHCP server, and does many2one NAT (one WAN IP) for each network, so each network can reach the Internet.
No rocket science required, no L3 switch (just L2 VLAN), and no static routes.

Thanks for the feedback but it's not how it is intended to be used.
But to further explain:
The router is set to manual managed mode, with a management IP address in a /29 subnet mask and we do not use DHCP or VLAN on router itself.We connect a Layer3 Cisco switch with multiple VLAN's setup on that switch and connected that switch via one RJ45 Gigabit connection to the router's LAN port 1, on the WAN port of the router a bridged-mode modem is connected in order for the router to be able to fully NAT the WAN IP.
MODEM:
Bridged
Router:
WAN: PPPoE connection setup
LAN IP: 172.20.0.6 /29Switch:
Management VLAN IP: 172.20.0.5 /29
Many other VLAN's which need internet via the router. (Hence multi-nets NAT required and static routes has been set)
Switch has ip routing enabled and routes all 0.0.0.0 0.0.0.0 traffic to the router.
Also access control is residing/managed on and by this switch.
So, can this function as intended this way or not?
- So no such thing like Muti-net NAT on the router.
In general, you need to make the router know about the other IP subnetworks, making the router know about the route to the core router - sigh, of course by adding static routes for each subnet, while the core router does make use of the BRx00 LAN as the default gateway.
The same applies here - it's not the way the BRx00 is intended to be deployed, so you might hit other possible limitations.Well ok then, thanks for your answer.
