rc.firewall-2.4.stronger problem - redhat 8.0

hello peoples
i've finally done what was needed and tried to upgrade my firewall on redhat 8 to the stronger one in the faq at TLDP for ip-masq, i think i have everything setup correctly, but when i try to d\run the new firewall, redhat complains-

": bad interpreter: No such file or directoryer: /bin/sh"

ive checked to make sure i have everything in oder (it appears to be), have attached a copy of my firewall ruleset in a zip, if anyone can help me it would be appreciated

btw im on dialup with dynamic ip assignment, with my internal interface being eth0, external interface being ppp0, on the 192.168.0.1 type network

[edit]
i have now fixed the problem, turned out there was an -e after the echo part which was causing it, AntiOnline won't let me delete the thread for some reason (closes connection) so just consider it closed anyway
