Is SCTP (Stream Control Transmission Protocol) supported by SonicWall Firewalls?

Is SCTP (Stream Control Transmission Protocol) supported by SonicWall Firewalls?

Basically SonicWall firewall is able to support all the protocols which listed under Network -> Services. By default, not all the protocols, which including SCTP, are listed there. 

So you need to define a customer service object to let the firewall knows the protocol. Otherwise, SCTP packets will be dropped as Unknow Protocol.

To do that, go to Network -> Services, click Add under Service Objects tab, Add Service window will display. Follow the configuration as below. Then click OK.
