I'm not sure if it's related to this one, but I have a similar problem.
The problem is unless I have port 27017 opened, Robomongo fails to connect even with "ssh tunnel" option.
Port, address and public key are correct, I'm using the same credentials to connect through ssh.
Here's the part of my iptables INPUT chain:
pkts bytes target prot opt in out source destination (...) 2044 191475 ACCEPT tcp -- any any anywhere anywhere tcp dpt:6666 state NEW,ESTABLISHED 54 6356 ACCEPT all -- any any anywhere anywhere state RELATED,ESTABLISHED 163 15426 DROP all -- any any anywhere anywhere
OUTPUT and FORWARD chains are empty
Looking at the traffic in wireshark I see that Robomongo doesn't try to connect to 27017, it connects to 6666 (as it should), but still fails.
What am I missing here?
