The hEX-S seems to be blocking certain (outbound) ports.
Connecting by RDP to a computer at an address like foo-rdp.my_dyndns.tld:3389 works great.
I can also access a website on the remote host when a port is not specified, i.e. https://foo-website.mydyndns.tld . . . or if I redundantly specify the HTTPS port, i.e. https://foo-website.mydyndns.tld:443
HOWEVER, connecting by SSH and/or HTTPS does not work
for example these do not work
- foo-ssh.mydyndns.tld:2200
- foo-webmin.mydyndns.tld:10000
Where do I start looking? Is this a firewall issue on the hEX-S (nothing is obvious there)? Something else?
After years' basic networking experience with other routers and then DD-WRT, I am new to RouterOS and configured this (my first RouterOS setup) for my Mom's home in January . . . with some (no longer available) help. BTW, from other locations I can successfully connect to the hEX-S and machines behind it, just not the other way around.
Thanks in advance!
