I\'m trying to setup port forwarding on a home router (Motorola Netopia) but the already setup VLans are preventing internet traffic to be forwarded on to internal IPs.

Internet Access is no problem, so the question is : whether these VLans are causing this issue or is it something else. I checked, the ISP is not blocking any ports.

If someone can help me with this that would be great.

This question came from our site for professional and enthusiast programmers.

VLANs cause IP packets to be tagged with additional information indicating which VLAN they belong to. This can cause issues if your network adapter driver or TCP/IP stack doesn't support VLANs or isn't set to accept frames from the same VLAN (or isn't set to accept frames from any VLAN).

I don't know the Netopia commands to disable VLANs off the top of my head but I would suggest you reset the router and configure it from scratch. It's unlikely that it's configured with VLANs by factory default.
