Which ports will Cloudflare work with?

Cloudflare can only proxy traffic going over the following ports listed below. If your traffic is on a different port, you should create a subdomain for that record and then add it as a record in your Cloudflare DNS zone file as something we don't proxy (gray cloud = no Cloudflare proxy or caching on a record).


For requests made via HTTP:

80
8080
8880
2052
2082
2086
2095

For requests made via HTTPS:

443
2053
2083
2087
2096
8443

On the pro plan and above, traffic on ports other than 80 and 443 can be blocked using WAF rule id 100015: "Block requests to all ports except 80 and 443".

80 and 443 are the only ports for HTTP/HTTPS within China for zones that has "China Network" enabled.

80 and 443 are the only ports for Cloudflare Apps to be able to proxy on.
