Hi DrDamnit,
All the methods are the things when you have an established open session with you.
You need to have a physical access to your machine if it is not responding to any of other connections over the network or a trusted source as per your ruleset.
By the way which way are you using Firewall Builder to build your firewall ?
Which OS are you using ?
Thanks!

Choose either one of:
1) iptables -F
will flush all rules with default rule to be applied to all packets
2) iptables-restore < /etc/sysconfig/iptables
will restore system defaults (if you have any)
3) iptables -F
iptables -A INPUT -j ACCEPT
iptables -A OUTPUT -j ACCEPT
iptables -A FORWARD -j ACCEPT
executed locally will force every protocol to be allowed (almost the same as turn off firewall).
