:8006`. 4. Enable IP Forwarding on the Host * For IPv4 and IPv6: ```bash sed -i 's/#net.ipv4.ip_forward=1/net.ipv4.ip_forward=1/' /etc/sysctl.conf sed -i 's/#net.ipv6.conf.all.forwarding=1/net.ipv6.conf.all.forwarding=1/' /etc/sysctl.conf ``` * Apply the changes: ```bash sysctl -p ``` * Check if the forwarding is active: ```bash sysctl net.ipv4.ip_forward sysctl net.ipv6.conf.all.forwarding ``` 5. Setup Network Configuration on Host 1. example of host network

6. Setup VM Templates 1. go to CT Templates Menu\ ![](https://2425195691-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FdbpAUu80KC7r7G8etEHT%2Fuploads%2Fv1pm2dmwp6KB5nZZasU6%2Fimage.png?alt=media\&token=bbbccce0-6c13-4389-b853-d8b104ecf4ad) 2. select template you want to download and add to your proxmox, you can choose any operating system ISO from here.

7. If your VM/CT can't connect to internet, use post routing command, make sure to chane the IP to your own local ip settings before. ``` iptables -t nat -A POSTROUTING -s 192.168.100.0/24 -o vmbr0 -j MASQUERADE ``` 8. use `chmod firewall.sh` to make it executable 9. add your forward port and setting ip automatically by using cron create new file firewall.sh ``` #!/bin/bash /usr/sbin/iptables -t nat -A POSTROUTING -s 192.168.100.0/24 -o vmbr0 -j MASQUERADE /usr/sbin/iptables -t nat -A PREROUTING -p tcp -d 0.0.0.0/0 --dport 20002 -j DNAT --to-destination 192.168.110.150:20002 /usr/sbin/iptables -t nat -A PREROUTING -p tcp -d 0.0.0.0/0 --dport 20620 -j DNAT --to-destination 192.168.110.151:20620 /usr/sbin/iptables -t nat -A PREROUTING -p tcp -d 0.0.0.0/0 --dport 20619 -j DNAT --to-destination 192.168.110.151:20619 ``` {% hint style="info" %} you can port forward every port accessing your IP to your own local ip:port directly. {% endhint %} add the file to the cron, use command `crontab -e` , if you're first time opening crontab, you'll be asked to choose which editor you want to use, default and easiest one is nano. ``` @reboot /bin/bash /root/firewall.sh >> /root/firewall.log 2>&1 ``` adding command above are making the network forward rule to be reloaded everytime restart/reboot happens to the machine. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
