I’ve just installed fs-1.0.4pre7 quick-and-dirty and tried to connect a softphone to fs, but the phone refuses to register. I have tried two different ones (EyeBeam and Zoiper), but neither can register.

I have turned off all firewalls(XP firewall, Outpost) on the client machine where the softphone is installed.  I can ping the freeswitch machine from the client and I can ping the client machine from the freeswitch machine.

The wireshark conversation is:

12           1.539643              192.168.10.11     192.168.10.29     SIP          Request: SUBSCRIBE sip:1000@192.168.10.29;transport=UDP

16           1.540027              192.168.10.29     192.168.10.11     ICMP     Destination unreachable (Host administratively prohibited)

where 192.168.10.11 is the client machine and 192.168.10.29 is freeswitch. Freeswitch is running on CentOS 5.3.

What is keeping the freeswitch machine from pinging the client?

Thanks, Lars
