Access to the admin panel on different port

[Krul]

For my local network I'm using IP range 192.168.2.x not the default 192.168.1.x Also I've changed the port for access to the admin panel from 80 to 8080.
Every time I try to access 192.168.2.1:8080 I'm getting this as an address in my browser (Firefox 26.0)

http://:8080192.168.2.1:8080/login.sh

and I have to remove manually the :8080 from the beginning so I can access the login screen. After I enter my password right I'm getting this

http://:8080192.168.2.1:8080/overview.sh

- again I have to remove the :8080 from the address.

I'm using:

Gargoyle Version:1.6.0
Model:TP-Link TL-WR1043N/ND v1
Device Configuration:Gateway
