Canopy ports for port forwarding

I have a Canopy 900 AP ( which is plugged into a Linksys router with a public ip. I like to access and manage my AP remotely from the office, which ports are needed to do so? Thanks in advance.

Just port 80 for the web interface. Do you need the full management suite too? This exposes a lot of area for attack from the Internet, connecting with a VPN is recommended.
