I am attempting to use the SuSEFirewall under OpenSuSE v10. The issue is, that while I may connect to the SIP port 5060 and place calls, when it connects no RTP comes through. If I stop the firewall on the Asterisk server of course it works like a champ.
Here are my settings:
#Eth card set to external zone
#Open TCP Ports
FW_SERVICES_EXT_TCP=“5038 5060 80 https ssh”
#Open UDP Ports
