[BC] Port Forwarding on the Shaw CGNM-2250

I just had my CGNM come and get hooked up, and was setting up my ports when I found out that at the moment the firmware only allows 9 forwarding rules to be set. Is there any way to increase the max amount of rules? If not then is there possibly a way to bypass it, or do I have to wait until there is a firmware upgrade that increases the max ruleset?
