Reverse Proxy IIS

Good Morning All,
I have recently decided to deploy Windows Server 2012 (standard) at home and have been working on getting most of the services that I had unique programs before using the build in functions. Either way IIS seems relativley unchanged from Win7 Prof so I have been trying to get the reverse proxy setup similar to the configurations for Sab, SB, & CP. I can connect to the mediabrowser link through "http://domainhere.ca/mediabrowser" but whenever I enter a password it gives the password error ("Unable to connect, please check your password and try again") and doesn't connect, I can however connect when direct (not through the forward on local LAN). I have enabled proxies in ARR and written in the URL Rewrite rule:
URL Rewrite Under "Default Site"
MatchURL
Requested URL: Matches the Pattern
Using: Regular Expressions
Pattern: mediabrowser(.*)
Ignore Case: Yes
Conditions: Default
Server Vars: Default
Action
Action Type: Rewrite
Rewrite URL: http://localhost:23424/{R:0}
Append: Yes
Log: No
Stop Proc Other Rules: Yes
Thanks for your help it is much appreciated,
