Cisco Routers :: WRVS4400N V.2 - Remote Management Through The Firewall

I'm attempting to configure remote management (and, sometime soon, SNMP) for a newly-deployed WRVS4400N v.2.At the Basic Settings page, I enabled Remote Management, and left the port # at the default. Remotely I entered the public (static) IP for the router in the address bar of IE8 similar to this: 67.203.???.??:8080. IE8's response is, "The webpage cannot be displayed." I'm using a public wi-fi access point, and don't know how the local router is configured, so it's possible that the local router has a blocking rule in the firewall.I'll try again using another remote router that I manage.
