Hi,
I just want to add my solution as I have found this topic with no results, too. So i tried some stuff and it was an DNS issue.
my setup
- 3 local PCs in the same network
- behind a firewall (nat)
PC A
- DNS set to Router/Firewall
PC B
- DNS set to internal DNS
PC C
- DNS set to internal DNS
Checklist
- Can't control A from B
- Can't control A from C
- Can't Contro B from A
- Can't Contro C from A
- can control from B to C
- can control from C to B
So everything where PC A was involved couldn't make a "local" connection. Tried several stuff like disabling firewall or reinstalling, enabling windows script host again, ... until i changed the dns from Router to internal dns. I have a setup here where the Router can not resolve Hosts that are registered in my dedicated dns server. Just check if "nslookup hostname" and "nslookup ip-address" gives a proper return.
I guess MonFlo checks for a local connection and tries to resolve it, but fails in this special case. Another hint might be: "direct connection" was displayed on all connection attempts. I haven't checked the network stack and how monflo tries to determine and connect to local pcs, maybe someone with much time can analyze wireshark traffic or a dev gives response to us, to clarify or confirm my guess.
kind regards
