all my proxies have two NICs (second NIC is on the same subnet as Data Domain to prevent going through firewalls). Second NIC was configured using your normal Linux procedures.

Thanks for the reply. If you login to the web GUI for your proxies, does it show both your NICs?

Can anyone from EMC confirm that using multiple NICs on the Avamar proxies is supported from a tech support standpoint?

So I talked to tech support about the multiple NICs, they are supported in 7.1 SP1 onwards. There's a KB for it, article #000460073.

Am I correct in thinking that the proxy is trying to connect to the host over port 902? If it's not the proxy, what's trying to connect to the host? I have the following line in my log (host.domain.com has been substituted for my actual server):

VDDK:NBD_ClientOpen: attempting to create connection to vpxa-nfc://[datastore1] apconline/apconline-000002.vmdk@host.domain.com:902

i don't think i have ever connected to the proxy via http, what port # ?

The port is 902. Do you know why the proxy connects directly to the host? Isn't everything done through vCenter?

i can't get to my proxies on port 902, tried http and https.

they need to connect to the host so they have access to the datastore on which VM being backed up resides ..because ultimately it needs to mount that vmdk to backup it up while VM runs off the snapshot.

Hi brastedd,

Can you gives us a more detailed picture of your environment?

In the past I configured proxy’s with multiple NICs in a VMware environment. If you add additional NICs tot he VM and reboot the proxy VM the NICs will show up in the Linux environment of the Proxy. Just logon to the console of the proxy and configure the NICs. The tricky thing is to get the routing correct. For each network not reachable through the default gateway you have to create a additional route
