I have never seen any port requirements for SBA which could make the engineers life easier. So, now here is my recommendation which ports should be opened between the appliance and the central site (absolutely based on my experiences and I never had problems):

SBA subnet <–> SBA Central Site:

  • UDP 1433-1434 (MS SQL)
  • http 80
  • TCP 135 (MS RPC)
  • TCP 389 (LDAP)
  • TCP 1801 (MSMQ)
  • TCP 2101-2105 (MSMQ)
  • https 443
  • TCP 444 (SNPP)
  • TCP 445 (SMB)
  • TCP 448
  • UDP 3478 (STUN)
  • TCP 5060-5100 (SIP)
  • TCP 6891-6901 (File Transfer)
  • TCP 8057-58 (PSOM)
  • http 8080 (Web service bridge)
  • https 4443 (Web service bridge)

 

SBA subnet <–> S4B clients:

  • TCP 49152-65535 (Media)
  • UDP 49152-65535 (Media)
  • TCP 5060-5061 (SIP)
  • TCP 5067-5068 (SIP)
  • https 443, 448
  • TCP 8057-58 (PSOM)
