@ -183,24 +183,24 @@ There is a couple easy and fast ways. One of them is port forwarding.
Just run [shell/addtables.sh](shell/addtables.sh) for default options.
```sh
@:/tmp/cloudcmd (dev) $ sudo iptables -t nat -L # look rules before
@:/tmp/cloudcmd (dev) $ sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 8000
@:/tmp/cloudcmd (dev) $ sudo iptables -t nat -A PREROUTING -p tcp --dport 443 -j REDIRECT --to-ports 4430
@:/tmp/cloudcmd (dev) $ sudo iptables -t nat -L # look rules after
# iptables -t nat -L # look rules before
# iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 8000
# iptables -t nat -A PREROUTING -p tcp --dport 443 -j REDIRECT --to-ports 4430
# iptables -t nat -L # look rules after
```
You should see something like this ( **8000** and **4430** should be in config as **port** and **sslPort** )
target prot opt source destination
REDIRECT tcp -- anywhere anywhere tcp dpt:http redir ports 8000
REDIRECT tcp -- anywhere anywhere tcp dpt:https redir ports 4430
```
target prot opt source destination
REDIRECT tcp -- anywhere anywhere tcp dpt:http redir ports 8000
REDIRECT tcp -- anywhere anywhere tcp dpt:https redir ports 4430
```
If you would want to get things back just clear rules ( **1** and **2** it's rule numbers,
in your list they could differ).
```sh
@:/tmp/cloudcmd (dev) $ sudo iptables -t nat -D PREROUTING 2
@:/tmp/cloudcmd (dev) $ sudo iptables -t nat -D PREROUTING 1
# iptables -t nat -D PREROUTING 2
# iptables -t nat -D PREROUTING 1
```
