Using snort but still want to pass traffic on port 80

[quangnd]

Dear all,
I am using snort to block all alerted IPs. But the problem is some of my customers are blocked on my service port 80. I wonder if there is any way to block all traffic from blocked IPs but port 80? If there is no way, I have to uninstall snort  :(
Thanks in advance,

Pls help me
