why are the RED 15 using udp port 3410 and not 3400 as the RED 10

Question

Is there a explanation on why the RED 15 are using udp port 3410 and not 3400 as the RED 10 
 We have 90+ RED 10 devices installed at customers and it gives us a loot of work and time wasted to change the port in the customers firewall. 
 Is it not possible to use the udp port 3400 on the RED 15 device ?

Hi Nicklas,

that's by design. Red 15 use RED V2 protocol

TCP Port 3400 (Control Connection, using SSL, authenticated with mutual X509 cert check)

UDP Port 3410 (Encapsulated traffic, AES256 (enc), SHA1-HMAC (auth))

Used Ports of RED -> www.sophos.com/.../122755.aspx

or take a look to this threat:
