Problem in Viewing office documents using Office Web App(OWA) Server 2013 in SharePoint 2013 externally

Hello All,

I have configured OWA Server 2013 with SharePoint 2013 with "internal-http" zone but when I switch over to "external-http" to access outside our network then viewing of office documents stops in internal also and not able to view externally also.

I think so, there is some problem in configuration.

I have used the commands as :

New-OfficeWebAppsFarm -InternalURL "http://OfficeWebApp" -ExternalURL "http://OfficeWebApp" –AllowHttp -EditingEnabled

Then checked "http://OfficeWebApp/hosting/discovery" works fine.

New-SPWOPIBinding -ServerName OfficeWebApp.intechsystems.local -AllowHTTP

Set the zone to "internal-http"

Then opened the Office document from SharePoint - works fine from internally but not accessible from externally.

then changed the zone to external-http with the following command

Set-SPWOPIZone –zone “external-http”

After this my internal access of office documents also stops.

I have tried with Set-OfficeWebAppsFarm –ExternalURL "http://servername.domain.local"

but still did not work.

Please help me to configure OWA for external use.
