Web-browsing with Satellite while playing on 56k

I have a mess with my ISPs...

For browsing I use satellite internet 40-150kps downloads but the ping is 700+ so I have to use a 56k modem for playing WoW and CS.

I have a dual screen setup and I was wondering if this was possible. I've tried several times to configure my router so that I could run firefox through a proxy but I have no clue what I'm doing.

Is there an easy program that I can use to set firefox to use my ethernet and games to use my 56k while they're both connected?! I can't seem to find the answer on my own.

 

If the idea is to use the Satellite to download while at the same time having a second active connection through the DialUp.

The answer is No can Do. Windows Client OS can Not work this way.
