Hi, I’ve just gotten a CRS326-24G-2S+ for my homelab. I have some previous experience with RouterOS on an older RB450G, but it’s been a while. Now, I’m not a network engineer, I’m a server guy, so I’m probably missing something obvious.
Reading up on the forums you need v6.41 to enable hardware-offload when running in RouterOS mode.
So, using my limited knowledge of RouterOS, I created 3 bridges and assigned interfaces to each bridge. The default bridge created on setup (Home) a server bridge (server) and a storage bridge (storage). All went well, until I tried a file transfer from an IP on the Home bridge over to one on the Storage bridge. The CPU maxed out at 100% and file transfer speeds suffered. Doing the same file transfer between 2 IPs on the Home bridge had 0 impact on the CPU, and file transfers where ~50% faster. So, looking into it, it seems hardware offload is only available to interfaces assigned to the default bridge.
This got me to thinking. How about I move away from bridges, to just having the default created one and using VLANs instead. However, I have no idea how to do that. Basically, I need 3 VLANs:
VLAN 1 - Home: ether 1 - 10
VLAN 10 - Server: ether 11 - 20
VLAN 20 - Storage: ether 21 - 24
In addition, I’d like to run a DHCP server from routerOS on each VLAN.
Any help would be appreciated.
