TCP 443 vs UDP 1194 and 161

What is the difference between TCP 433, UDP 1194 and UDP 161

For frequent everyday use and those that are on a normal network etc, it is best to use UDP 1194.

If you are on a restricted network or in a country with firewalls/restrictions (China) etc, use and try TCP 443 or UDP 161.

TCP 443 on most networks is allowed as this is used for SSL

UDP 161 is used for SNMP


UDP is used when speed is desirable and error correction is not necessary. For example, UDP is frequently used for live broadcasts and online games
