Routing with 3 public IP addresses
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Team,
I have a customer with 5 public IP addresses; all within the same subnet (i.e. /29 - 255.255.255.248).
Lets assume these adresses are 90.70.50.202-206.
I would to use 3 of these on a ER605 without any load balancing or backup.
These three are 90.70.50.202-204. The default gateway is 90.70.50.201.
Is this supported? Assuming yes: how do I set this up?
With warm regards - Will
On er 707-M2 it is on internett settings and advanced and then ip alias
the only problen is that when I do a port nat i cant use port that alredy used in primary ip address. i have to use DMZ to get it to work if port alrady used on a another ip.
@Clive_A is there somthing I do wrong or what?
this is message when try to add a port nat, and this port is not in use on my secondary ip, if I use dmz everything work but then i have to use acl to first block all and then open port i want to use
and I prefer to use port nat because that way I could nat to different devices on the lan, dmz locks to only one device on lan
I mention I use ER707-M2 and im not sure about ER605, But my guess is that this is on this router to.
and I use secondaty ip one same wan port as my other ip, if you want to use different wan port for every ip you can problably configure that and use policy route to route client to different wan port, but i dont understand the point with that.
then you will need a switch on wan and connect every configured wan port to the switch included ISP router and everything should work i guess.
And what i meen with dmz is that this was the only option to nat in to lan when port alredy used on another nat with same port is used on another wan ip.
