fwbuilder automatically generates a rule with "clamp-mss-to-mtu"  
option when you check appropriate checkbox in the firewall settings  
dialog

otherwise, you can add any custom rules using the "prolog" or  
"epilog" sections of the generated script; these sections are located  
in one of the tabs of firewall settings dialog
