Does anybody have any experience with adding a WFE which is in a DMZ?
Trying to do this for a client and whilst the correct ports seem to be open, the install/config script dies on the step to provision the Distributed Cache.
All of the appropriate ports (22233 to 22236, inclusive) are open in the firewall and telnet tests indicated that they are working.
Trying a "user-cachecluster" yields an "ErrorCode:SubStatus:Failed to connect to hosts in the cluster" exception.
Trying "connect-afcacheclusterconfiguration" gives the same exception and "Get-AFCacheHostStatus" gives "ErrorCode:SubStatus:Cache host is not reachable." for each of the existing servers in the farm.
A literature search on these errors yields some results but nothing that has helped nor anything relevant to the scenario of adding a server in a DMZ.
In case it helps...
discusses using "Export-CacheClusterConfig" to confirm the config in case there is a rogue entry.
In this case, the new server I wish to add is missing and there does not appear to be any incorrect entries.
I started to go down the "rabbit hole" of trying to add it myself but then ran into other similar issues.
As you can expect, this is becoming quite stressful and urgent; any ideas/advice would be appreciated! Thanks in advance...
