1800 SMB Internet VLANs

[franctorres]

Hi mates good day,  we are deploying a 1800 in a costumer but we are having problems trying to configure some sub interfaces in the internet link (The only that allow us to have default route) is there any steps we can follow to achieve this?

Regards

Why do you need sub-interfaces on WAN link in the first place?

Can we relocate the post to SMB ?

It is already done

Hi Val, our costumer is public sector costumer and uses the goverment service provider and they give in the same link access to the internet and connection to the goverment internal net.

So this is part of their topology.

If you can split those, DMZ NIC can be used as a second WAN

While you can configure the WAN interface to be on a VLAN, I don’t believe you can configure the WAN port to have multiple VLANs.
However, I believe you can configure one of the LAN ports with multiple VLANs (one of which is Internet-facing).

You should be able to create several tagged Vlans on each port.

It is done by creating a new Internet connection, checking on the "Use connection as VLAN" and setting the "VLAN ID:" with your chosen tag. 

The overall limitation of 32 Internet connections includes the tagged connections.
