Question

Goodmorning,

I need to create a NAT 1:1 .

I need to map an internal address (LAN) to an external address (WAN ). For every entry inside the NAT 1:1 table, the RUT240 gateway will create a new virtual IP address on its WAN e. The LAN device associated with that entry then becomes accessible at this new virtual IP address.

It is possible to create this funtion?

Can you help me?

Thanks beste regards

Hello,

Thank you for reaching out!

We have a great Wiki article on how to set this up on RUTX devices, however, everything should also apply to RUT240.

The basic summary is:

• Static IP needs to be configured on the WAN interface;
• In Firewall -> Custom Rules iptables rules can be added:
  • iptables -t nat -I PREROUTING -d ROUTER_WAN_IP -j DNAT --to-destination SERVER_LAN_IP
  • iptables -t nat -I POSTROUTING -s SERVER_LAN_IP -j SNAT --to-source ROUTER_WAN_IP
      

Let me know if you encounter any issues!
