Encryption over WAN

Post by lhundt » Dec 09, 2009 4:17 am

We enabled the encryption option using the vStorage APIs with VEEAM Backup 4 and I had a quick question about the ports used to transport the backup. We are seeing port 902 being used when the encryption option was turned on. After doing some quick searches, it appears that 902 and 443 are the native encryption ports that VMware uses for communication between hosts and virtual center. We just wanted to verify this was the case and should provide a good encrypted tunnel between our primary site and recovery site. Thanks!

Hello Lance,

Yes, that's right. 902 and 443 ports are being used when you choose "Enable Network Traffic Encryption". This mode can only be used while doing backups with vStorage API Network mode, in this case all traffic is encrypted from your source host to a Backup Server.
If you're performing replication jobs between two sites, I believe you're using some sort of a VPN connection, which already provides security for your traffic flow. You may find more information on ports in the User Guide which is available on our website.

Hey Vitaliy,

Thanks for the quick response! We are not using a VPN connection between the two sites because we have a large university system network that connects our branch campus and us. Basically we will be doing monthly or quarterly backups from one campus to the other. We take weekly backups and store them locally. Basically by sending quarterly backups offsite will eliminate our need to write them to tape and transport offsite. Thanks again!

Lance
