Alternative to bridging?

Hi all,

On a LAN-interface (ether1), I have created VLAN20 that I bridge with the WAN-interface (ether5). This way, computers in VLAN20 can get a public IP from my ISP (via DHCP).
Ether1 has some other VLANs too, but these have internet access via NAT.

Is is possible to replace the bridge with something faster? Preferable wire speed via the switch chip but I gather routing is also faster than bridging?

thanks for the tips!

Added an overview of the test setup:-)
Actually, simplified: I need to put the WAN-port (ether5) in native VLAN1. And I need my trunk port (ether1) in native VLAN1 and in VLAN10.
Devices in VLAN1 will then get a public IP. Devices in VLAN10 will need inter VLAN-routing to reach the internet (which ROS does by default).

The hard part is configuring the switch chip to accomplish this. On DDWRT for instance, this is a 5 minute job:-).

cheers,
Jeroen

ps: below, in the picture, you can see that I’m using VLAN20, which I have put in a bridge together with ether5 (= the WAN port). I want to get rid of the bridge and use the switch chip.
