kindly help,
I am new to iptables and I wish to allow my workstations behind a firewall
to get registred to h323 gatekeeper and sip proxy (the two servers are on
public ip i.e. outside nat).
And for h323 gatekeeper, the workstation need to connect with port 1720 and
iptables does not allow this.
And again the sip proxy too needs port 5060. can somebody please help. My
firewall tables is as below.
