Re: How Do I Enable Access Proxy Check Box on VBP 5300
On the E box you leave it disabled.
On the ST box, you have to first change the HTTPS secure management to use a different port. If you look at the top of the access proxy page, there is actually a link there to go to that section of the UI. Or, you can also get there by going into the Security section and then HTTPS configuration.
From there, you can change the port from 443 to something else (like 445). The only ports you can't use are 389, 443, 1719, 1720 and 5222.
