DoS setting between SD-RED60 and SD-RED50

Hello Jirayu Siangsai ,

Thank you for reaching out to the community, both the RED series and SD RED series uses the same ports so connection should 'nd be a problem in first place
TCP 3400 + UDP 3410 where:
> TCP port 3400 (Control Connection, using SSL, authenticated with mutual X509 cert check)
> UDP port 3410 (Encapsulated traffic, AES256 (enc), SHA1-HMAC (auth))
