Block incoming ports on Cisco 2620 with IOS 12.1 w/FW

Can someone tell me a quick and dirty way to block ports on the above mentioned layout? I am trying to avoid access lists if at all possible, because I do not have the time now to fully hash out all needed ports. Basically, I need to be able to block the ports associated with the MSBLAST worm currently going around now, as my router is being flooded on the vulnerable ports. Thanks in advance!

I am using PIX 515 and this is what I did in my firewall associated with the worm.

access-list out2in deny tcp any any eq 4444

access-list out2in deny tcp any any eq 135

access-list out2in deny udp any any eq 69

Yes, I wish the ACL's were that simple on a 2620, but alas, they are not......
