Hi, can somebody give me voobly server ip. My isp can improve my internet routing if they have server ip from which it route better to south americans, as with them I have bad latency.

Hi.

Check this : https://support.voobly.com/display/vkb/KB1012+Required+outgoing+firewall+configuration+for+Voobly

Hope it helps.

Also, you'll need to check if you experience fast/slow proxy issues. It depends if you forwarded correctly your 16000 UDP port (default one). This usually helps a lot and prevents high latency/unwanted drops.
