[TriLUG] Road Runner blocking ports?

[Dave Sorenson]

Sorry if this suggestion was covered, too fried to remember, but have 
you added the FTP connection track module to iptables? I had some 
problems with a cent OS  upgrade until I loaded the module via 
/etc/sysconfig/optables-config

# Load additional iptables modules (nat helpers)
#   Default: -none-
# Space separated list of nat helpers (e.g. 'ip_nat_ftp ip_nat_irc'), which
# are loaded after the firewall rules are applied. Options for the 
helpers are
# stored in /etc/modules.conf.
IPTABLES_MODULES="ip_conntrack_ftp"
