I've been able to access the filewall file and the results by going to vi /etc/sysconfig/firewall

This will make the rules persistent across reboots. You can see the general commands to open ports up if you search for the appropriately commented areas.are:
Code:
#!/bin/sh

#fix for passive ftp connection tracking
/sbin/modprobe ip_conntrack_ftp

# Drop ICMP echo request messages sent to multicast or broadcast addresses
echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts

# Drop source routed packets
echo 0 > /proc/sys/net/ipv4/conf/all/accept_source_route

# Enable TCP SYS cookie (DoS) protection
echo 1 > /proc/sys/net/ipv4/tcp_syncookies

# Don't accept ICMP redirect messages
echo 0 > /proc/sys/net/ipv4/conf/all/accept_redirects

# Don't send ICMP redirect messages
echo 0 > /proc/sys/net/ipv4/conf/all/send_redirects

# Enable source address spoofing protection
echo 1 > /proc/sys/net/ipv4/conf/all/rp_filter

"/etc/sysconfig/firewall" 88L, 3244C
does that mean anything?
