[Freeswitch-users] SBC not responding to syn

Hello Freeswitch experts ! I have a new setup as below and it is not responding to any syn request --------a-FS SBC-b—----------------External SBC In the above setup, the b side of the sbc has two IPs - one of them is a public IP External SBC is sending syn request to interface b and to the public IP and I can see this in the tcpdump on the FS SBC but I dont see the FS-SBC responding. When I do netstat, I do see the freeswitch listening on that IP and port. All the firewall stuff on the vm has been disabled Acl is updated on the fs. Any thoughts and suggestions will be greatly appreciated Regards A
