Answer 1

Here is what I came up with to run sshd on 443 and 22 having rhel8 on ec2

1. make sure your security groups allow connection from your network/ip to the desired ports (in my case 22 and 443)

tcp 443 1.2.3.4/32 #allow access to 443 from IP 1.2.3.4
tcp 22 1.2.3.4/32 #allow access to 22 from IP 1.2.3.4

2. Login to the EC2 and

#install semanage with
sudo yum install -y policycoreutils-python-utils
#delete 443 from http ports
sudo semanage port -d -t http_port_t -p tcp 443
#add 443 to ssh ports
sudo semanage port -m -t ssh_port_t -p tcp 443

3. Edit /etc/ssh/sshd_config

Port 22
Port 443

4. Restart sshd

sudo service sshd restart
