Region : Canada

Model : TL-ER5120

Hardware Version : V1

Firmware Version : 1.0.2

ISP :


I'm just starting to build this router / firewall.

I see that I can assign different VLANs to the physical ports. However, I can't see how to build a unique subnet for each VLAN. This type of configuration is typical in an enterprise network since it provides a great deal of flexibility. Am I missing something in the configuration? I've looked at the relevant portions in the documentation and I can't find any help there. Basically, my questions are as follows.

1. Can I assign a dedicated Subnet per VLAN?
- VLAN 1 = 192.168.1.0 / 24
- VLAN 2 = 192.168.2.0 / 24.
2. If so...can I build ACL's or firewall rules between the subnets?
3. If I can't do either, how can you call this an Enterprise router?

Just seen your thread >. I have just been asking the same question. Yes it is a budget product, but it clearly misses the SMB market with such limited sub-netting.
I bought one assuming it would have a basic set of flexible VLAN options ,QVLAN and PORT based VLAN,s but it seems to be a WAN fail over switch in a big box.
I also cannot believe how basic the firewall options are. Not suitable for SOHO let alone SMB. Enterprise. ? Yeh Right....
