We are trying to setup a new customer with an RF550 VPN and the internet service company wants to know what port number the RF550VPN does VPN traffic through.

RF550VPN is based on the IPsec standard, IPsec uses protocol number 50 and 51, this is not the same as port number. Also IPsec IKE uses port 500 to setup VPN connections.

For more information regarding the IPsec standard, visit this web site:
