terox 316 Posted April 3, 2017 servers only use 4 ports so have no idea why your setting it up for 8 Maybe you need to revisit the port section in the tutorial thread in this forum What I did find after the 64 bit exe came out was that I also needed to add a rule for the actual 64 bit binary as well (And I still dont know why) Share this post Link to post Share on other sites
tRiKy_ch 26 Posted April 4, 2017 where is your server? i saw i similar issue, it was caused by a firewall setup on server ip by provider (ovh) Share this post Link to post Share on other sites

I've seen people not being able to see nor connect because of the provider firewall config (or routing config). However it was on the default port. Note that if your provider has an anti ddos thing it is possibly dropping every udp packets until a tcp connection is initialized. Don't ask me why but it is weird af.

Don't ask me why but it is weird af. very very weird, from my home ip a can connect to rcon only if i previos logged on ssh, else if i try it from my mobile (it has another ip class) it connect every time 8-) Share this post Link to post Share on other sites
