How to configure a NAT pool in Ruijie RG-EG1510xs

I have a leased line from ISP with 6 usable public IP. How to configure them? I cannot get it entirely correct when trying to configure it. I have it on the WAN interface and only the previous configuration (before the update) is working. If I try to add the 5 more ip's it breaks the internet.

Dear sir,
If I understand correctly, do you want to configure multiple public IP addresses on one WAN port of the RG-EG1510xs?


Best Regards,

Yes. I want to configure multiple public IP on one WAN port as per latest firmware it is possible. But how? When I tried to put the additional public Ip's on the Nat rule, the internet on the WAN port stops working.

Dear sir,
May I know if the current version of your device is 410?  And yes, you need to achieve this by NAT rules. One rule can only configure the WAN port IP of one network segment, but multiple rules can be configured to implement WAN port IPs of multiple different network segments.

If still not work, please contact us via live-chat. ( www.ruijienetworks.com/rita), We need to check the configuration further.

Yes. I updated this morning to the latest firmware 410. I have multiwan. On wan port is the leased line from ISP where it gives me a /29 ip block but currently using only single static public ip that belongs to that /29 ip block. The wan1 and wan 2 ports are ppoe connections from ISP. So after updating to the latest firmware I set up wan port NAT by adding username, etc .and the additional IP I have just like on the picture you gave me, but on the pre nat destination zone I choose the custom -WAN interface because it is where the leased line is plugged. On the post nat packets I choose the Ip range and then put the IP/29 block. But the internet stops working then resumed intermittently and routing goes to the wan 1 and wan 2 but very unstable, just like no internet at all or takes a very long time to load pages. So where did I go wrong?

Dear sir,
On the post nat packets, have you tried set as "Specified IP" if you know the specific IP address from the ISP?
