将端口从80和443转发到8080

Question

I tried to forward port 80 & 443 to 8080 on a server that I am working on https://www.neptos.io

My Angular Universal app is running on 8080 but my default angular app is running on port 80 & 443 (https)

I forwarded both port 80 and 443 to 8080 via iptables using:

iptables -t nat -A OUTPUT -o lo -p tcp --dport 80 -j REDIRECT --to-port 8080
iptables -t nat -A OUTPUT -o lo -p tcp --dport 443 -j REDIRECT --to-port 8080

Now when I ssh into the remote machine and run curl localhost, I get the desired result which is the angular universal app but when I open, it in a browser https://www.neptos.io I get the default angular app.

Am i doing something wrong here?

Any help would be appreciated.

I believe the OUTPUT chain will only effect traffic generated on the localhost. To redirect incoming traffic you need to use the PREROUTING chain.

 iptables -t nat -I PREROUTING --src 0/0 --dst 127.0.0.1 -p tcp --dport 80 -j REDIRECT --to-ports 8080 

Just replace the localhost ip with what ever your interface IP is
