hi tom
there are severall things to considure if you want to backup a client in dmz. do you need filesystem backup or also integration backup.
- Make sure nameresolution does work on both directions!!! from the cell server, you need to resolve fqdn (dmzserver.domain.local), from dmz server, you need to resolve fqdn from cell server (cellserver.domain.local). if you have a dedicated media agent, this host needs do resolve dmz server and cell server as well. i think cell server is also media-agent?
- you need to open tcp port 5555 (default dp communication port) from cell server to dmz server.
- you need to open tcp portrange for "backup stream data". first on the media agent, first copy omnirc.tmpl and then rename the copy to omnirc. (if you not already have this) then go to the line "ob2portrangespec". modify with a port range. for example:
OB2PORTRANGESPEC=xMA-NET:20100-20150
now all data streams for backup/restore use this port range (DA->MA) - now configure your tmg to allow tcp 5555 from Cell Server to DMZ Server and TCP 20100-20150 from DMZ Server to Media-Agent (Cell Server??)
- test if you can telnet dmzserver.domain.local 5555 from cell server. if you can't connect. something with name resolution or tmg firewallrules are wrong.
- if you setup everythin right, it should work now
