Hi

I have a Cisco SMB router RV220W. MY ISP has given me 5 Public IP addresses. I want to map these Public IP addresses to my private (Local LAN IP) IP addresses in one-to-one basis. I have done this in the router as Private IP --> Public IP --> Range. But I can able to reach the first public Ip address to private Ip mapping from outside. I couldn't able to reach other public IP addreses to Private Ip mapping. I have allowed the related services in the firewall rules also. But still i can not able to reach & use the other public IP addresses. It would be great if someone helps..

Thanks In adv..

I have that router. I am fairly sure the input is only one IP. I looked at the configuration and it won't support multiple input IP addresses.

Hi innocentdevil,

Tried the above link but still the problem persists. What I feel one-to-one NAT rule is not properly tying the public ip to the local lan ip....

I have a sibling RV042g router that allows 2 IP addresses for failover, but that is the most I have seen in small business commercial routers up to about $1,000. You may need to use multiple routers.

Could you please be so kind as to post the paragraph in the documentation where it says this?

I will check my own later, but I did not see anywhere where it said this and did not see in the setup where it said this, but I may not have looked deeply enough.

As I said, I will check again this evening on the actual router.

But I read the documentation again. The RV220W supports 5 VLAN's and multiple tunnels, but I cannot find anywhere where it says it supports 5 external IP addresses.

Please help us with a link.

I am looking at my RV220W setup. It cannot do 5 external IP addresses. I hope that clears your doubts.

Yes, I am a Topic Advisor. If I remove the link (links can and do vanish) then the post says nothing at all. That is why we (all of the Topic Advisors) delete blind links.

If there is something in the link that points to different to what I said above, please say and then use the link as support.

I trust you see my logic and process now.

To follow up, there was nothing in that link that said it supported 5 IP addresses. The little it did say is that it might support 3.

We need an authoritative post / link (with description ) that says what the RV220W can do.

I will go back and look at my own.

Here is a picture of the RV220W IP4 WAN setup. I do not see much flexibility there.
