cornfedsip: voip and sip protocol problems

Yes,

the bidirectional checkbox doesn't work properly. After setting up guarddog 
correctly for the UDP 5004 port I looked back in the exported script and the 
connection is NOT bidirectional.

Modifiing the script manually in the way shown below solved the problem:

Original:

# Allow 'userdefined6'
iptables -A f0to1 -p udp --sport 0:65535 --dport 5004:5024 -j ACCEPT

and 

# Allow 'userdefined6'
iptables -A f1to0 -p udp --sport 0:65535 --dport 5004:5024 -j ACCEPT

modified to:

# Allow 'userdefined6'
iptables -A f0to1 -p udp --sport 0:65535 --dport 5004:5024 -j ACCEPT
iptables -A f1to0 -p udp --sport 5004:5024 --dport 0:65535 -j ACCEPT

and

# Allow 'userdefined6'
iptables -A f1to0 -p udp --sport 0:65535 --dport 5004:5024 -j ACCEPT
iptables -A f0to1 -p udp --sport 5004:5024 --dport 0:65535 -j ACCEPT

greetings
