From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

First obvious question: do you have a firewall enabled?
From a terminal, type "iptables -L" and if there are any rules there (rather than just category headers) you will probably need to allow inbound traffic through the firewall
thanks for help. i tried adding firewall rules to allow all udp connections (added my iptables output in the op), but no luck :(
Yeah your iptables is already set to up ACCEPT by default meaning no blocking.
My next step would be to determine whether the traffic is reaching the target machine. Look into how you can monitor inbound traffic and verify whether the server even sees the inbound connection attempt
yeah thats the first thing i wanted to check. im not a network expert but i think my phone tried connecting to my machine. on the log,
SRC=192.168.43.60
is my mobile phones address, but I cannot confirm it was a success or not.ive created a pastebin here just in case.
There is no traffic on Port 8081 in those logs
Yeah thats syncthings doing (¶ _ ¶)
I mean to say that the connection attempt is failing because the traffic is never reaching the server.
