Setting up router/repeater for Commercial WIFI

Ok - I will try to explain as best I can.

I work in an office. Outside the office is WIFI that anyone can purchase time on and use (up to one month). The signal is weak in the office. I have purchased the following equipment:

ALFA R36 router, Firmware version 1 point 2 point 0 point 7
ALFA AWUSO36H USB Long Range antenna

The goal is to allow people in the office to connect to the wifi outside the office, purchase whatever accounts they need, and use the internet.

Issue:

Connecting the USB long range antenna to the R36 router, the router easily picks up the outside signal. There is no issue with signal strength.

In the office, everyone is able to connect to the router just fine.

Now, what happens is that when someone uses the router to connect to the commercial wifi service - they are able to see the initial login screen, but are unable to go outside to the wider internet. TRACERTs stop with the IP address of the Commercial WIFI network. DNS resolution is taking place (domain names are properly translated), but the tracert stops at the Commercial WIFI network and will not go forward.

When someone connects directly with a device to the commercial wifi, the TRACERT information is surprisingly the same - all the TRACERTs stop at the commercial wifi network; however when using internet explorer or firefox external websites will resolve correctly.

I am using DHCP on my router to connect to the Commercial WIFI in question. I have DNS resolution, but I'm being blocked on Tracerts.

I have tried all the little settings on my router, but have been unable to figure out how to get this to work. My assumption is that the Commercial WIFI is set up to allow or deny access based on specific MAC addresses. Is there a way to have my router in the office provide the MAC address information to the Commercial WIFI?

Any help would be appreciated. I looked at the how-to's, but I couldn't see the pictures due to filters in place.

Me
