RV220w one-to-one NAT with multiple targets

[sflaci]

Hi all,

I have a small network with 5 IP's externally. The firewall is updated to the latest 1.0.4.17 code.

I would like to be able to use the same external IP with multiple servers on the backend.

Example:

External IP 100.100.100.100

Internal IP for SMTP 192.168.1.10

Internal IP for HTTPS protocol 192.168.1.20

Internal IP for RDP protocol is 192.168.1.30

Is one-to-one NAT the best way to accomplish this?

I also see an option under Access Rules where I can specify "Use Other WAN (Intenret) IP Address".

What is the difference between doing one method or another? Any pro/con for going either way? The One-To-One NAT seem to be easier for me, but looking for the best way to do it.

Thanks very much in advance!

Hi Laci, I have never tested using multiple servers like that tied to 1 address. However, you are correct, under the access rules, specify whatever service you want then choose the option for using the other WAN address. This should theoretically work provided there are no over lapping services.

Thanks Thomas!

Is one method preferred over the other? Is there any functional difference using access rules versus one-to-one NAT?

Thanks again!

Theoretically, they both accomplish the same thing. I just happen to have a lot greater success using the access rules and I feel there is somehow a better flexibility.
