Then create a rule in TMG to allow traffic from the backup exec media server and localhost, to localhost and the backup exec media server. You need to allow port 9000, and also any ports you have declared in the dynamic range on your BE media server Options>Network&Security Page (all TCP outbound). I also restarted the backup exec remote agent on the TMG server and made sure only one instance of the process was running using task manager. Re: Backing Up 2k8 R2 Server with TMG 2010 Installed IT WORKED! I'm not sure whether it was changing the UDMP service port to 9000 from 12050 that did it, or whether it was killing the beremote.exe process and restarting the service that fixed it, but I can now select the files and folders from the BE server. Access seems to be very slow, so I don't know how successful the backup is going to be, but I'm at least a step forward. Thanks once again. Re: Backing Up 2k8 R2 Server with TMG 2010 Installed hmm, this is bad news. I'm ok with having a script backing up the config as a temporary measure, but ideally I'd want this in with all my other servers. Hopefully it's something that will get fixed in a future patch, either from BE or TMG's end. Thanks. Re: Backing Up 2k8 R2 Server with TMG 2010 Installed It looks like I can only create an "All outbound traffic" rule. Which when selected I get denied requests on port 10000, these are allowed when the rule is in place as it was initially. I have the backup exec media servers in the from and to tabs, and also the TMG servers in the from and to tabs, so traffic should be allowed both ways. Re: Backing Up 2k8 R2 Server with TMG 2010 Installed Good idea, I'll try that now. Re: Backing Up 2k8 R2 Server with TMG 2010 Installed Thanks, I can see that the media server is trying to access my server via port 10000, Microsoft CIFS and PING. All of which are allowed in my rule from the media server to the TMG server. Re: Backing Up 2k8 R2 Server with TMG 2010 Installed Hi Colin, according to the Symantec article posted above you do not have to change the port on all media servers and remote agents if you're using version 11d and above, which the OP is. I am also getting this problem and finding myself increasingly frustrated with not being able to backup my TMG servers. The quote from the article is Note for Backup Exec 11d and above:The steps above can be done on the only the server/s affected. All other remote servers can have the existing/default NDMP Port. I'd appreciate any advice you can give.
