I was trying to set up a rustdesk server on my docker appliance. For some reason I can’t get traffic from any remote computer to route through port 21116. I’ve verified that the traffic is leaving my desktop, going through my router, and passing off to the internet. My ISP is set up in bridge mode so that shouldn’t block this port. I can’t seem to figure out if the the traffic is getting to my route10. How can I verify traffic on port 21116 to the WAN sfp port?
Thanks,
Kelly
Could we have a screenshot of how the port forward rule is currently setup?
Could also try something like this: Open Port Check Tool - Test Port Forwarding on Your Router or Nmap: the Network Mapper - Free Security Scanner from a remote computer to see if the port looks to be open.
Wanted to do some more testing on my own. Here’s a shot of the rules. 192.168.0.173 is my docker server. All other apps on this are working (nextcloud, photoprism and plex).
I’d try using tcpdump to confirm that the packets are arriving on your WAN interface (W1 = eth3 and W2 = eth4) and exiting your LAN interface (br–lan).
Something like:
tcpdump -ni eth3 tcp port 21116(May need to change to eth4 if using SFP W2)
and
tcpdump -ni br-lan tcp port 21116 (assuming default LAN)
You can open a terminal by holding the Shift key + clicking on the R10 name or via SSH
Using tcpdump I can see the traffic coming into the route10. I don’t see it going out to the port that has 192.168.0.173 on it.
Could you try removing the port range on the “redirect to” so that it is only 192.168.0.173?
OK, now I can see the traffic to the right instance. Still not responding so now it’s something in the docker config. More later.
Thanks for the update
I’d check the firewall/allowed ports on the docker and if it has a static IP, make sure the gateway is correct.
Figured it all out. Thanks for the help and patience. Multiple issues and had to knock them down one by one.
