Using Public IP Address for host on the network

[shehussubnet]

I want all hosts on my network to use dedicated Public IP addresses.

I am connected to my ISP via a /32 and there is a BGP peering with my ISP to advertise my block of public IP addresses

Do I still need any form of address translation for my Public IP address?

if you have public block and AS number which is reserved to you by place such as apnic, you can do BGP peering with ISP and no need to do translations. ISP will advertise your AS number and IP range to internet. make sure you are entitles to use those ip addresses and AS number. you cannot use any public IP range inside your network, if you planned to connect them directly with internet.

Thank you for the response.

The solution is already working on another router. We are only replacing
the router with a Cisco router.

I can ping google from the router but I can not from the devices using
public IP

check your default route and default gateways of end points. they should configured properly.

Thanks. Does ip name-server has any effect on ability of my devices
(using WAN IP) to connect and communicate?

for ping test using IP address, it is not an issue

Hello
As long as that dedicated public ip address you use is reachable to your wan rtr then it shouldn’t be a problem, however you mention BGP and NAT
Do you have multiple egress points? (mpls and internet)?

Can you post a simple topology diagram

I am wondering about this part of the question "Does ip name-server has any effect on ability of my devices" I am not sure what is behind this question and why they think that something about name server might be an issue. But if there is some issue about name server it certainly could impact devices. And if devices are having difficulty in resolving name to address it would impact ping as well as HTTP/HTTPS etc.

And thinking about ping I find this statement interesting "I can ping google from the router but I can not from the devices using public IP". I am wondering if these pings are using names (which would require DNS resolution) or are using just IP address (which is a much better test if checking IP connectivity is what you are trying to do).

This statement is also interesting "The solution is already working on another router". That suggests that there are differences in configuration between the Cisco router and the original router. So can we see the appropriate parts of the config of both routers?
