The port that plugs into your router will need to be placed in Trunk mode with the desired VLANs in the Trunk port. All ports are by default in access mode for VLAN1, this means that the port that plugs into your routing device is in access mode for VLAN 1 and is why VLAN 1 has internet access. For VLAN 2 traffic to have access to the routing device you will need to change that port to Trunk mode and add VLAN 2 as a Tagged VLAN. Page 468 of the user guide details where to set Tagging at.

Good afternoon! I am looking to implement a 5548 into our existing infrastructure. I want to preface this by saying that I am very new to networking. I am looking to have at least two separate vlans. - The first vlan for public facing sites. These will get static, public IP addresses. - The second vlan is for iSCSI traffic. I would like this to not be public facing. Is this configuration possible or should I be looking for a different solution. If this is possible, how do I go about setting it up?  Thank you!
