# Whitelist ports in case you are under a Firewall

There might be some cases, where your connection is filtered by a firewall, for those cases, if you are having issues with connecting or using Toky, please enable those ports to guarantee the overall good performance of Toky:

**First try opening the following ports and do a test:**

* \_TCP only:\_10443 and 10444
* *TCP and UDP*: 3478

**If the problem persist, open these other ports in your Firewall**

* \_TCP only:\_5090
* *TCP and UDP*: 10000 to 65565.

Also if the firewall allows it, prioritize everything on \*.[toky.co](http://toky.co/)\
