MX 84 outbound IP

[Raffa76]

Hi,

i've a pool of public ip's.

i've set 1:many NAT a lot of services on a server, but, in outgoing the ip of the server is the default public ip;, is there a way to set, for a server, a different public ip?

thanks

best regards

Hi @Raffa76 . No, you cannot do source NAT on the MX like you are asking. You can use your pool for inbound connections, but you cannot use it for outbound. That will always use the interface IP of the MX.

This is not entirely true. 1:1 NAT outbound traffic will use IP set in 1:1 NAT.

However in this situation you would be correct. OP would need to convert to 1:1 NAT.

Hi @JasonCampbell. It will only use it in reply traffic. Any connections initiated from Inside will not use the 1:1 NAT IP.
