Subject: [Freeswitch-users] SBC not responding to syn
Message-ID: <MN0P223MB12296CC2C6BFDDE34F96EDF6B3EFA@MN0P223MB1229.NAMP223.PROD.OUTLOOK.COM>

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

Please ignore this, I resolved this with a return route on the van

Thanks
