ACE on a stick with SMTP and the source IP

Hi,

 

Does anybody know if the ACE has the ability to advise the downstream SMTP servers of the original source IP client address when the ACE is deployed on a stick? Currently the SMTP servers are just seeing the source address of the load balancer because of the SNAT. We are using x-forward for the HTTP traffic and that works a treat.

 

Anyone come across this before?

 

Cheers

Hi,ACE cannot insert headers

Hi,

ACE cannot insert headers for "SMTP" and as a workaround you can either make ACE as default gateway of "SMTP" servers or do routing on servers, that for SMTP the next HOP is always ACE. That way you don't need to use NAT on ACE.

Hi Kanwal, yeah I was looking

Hi Kanwal, yeah I was looking at this but was hoping there's another resolution with out changing the under lying infrastructure - for example the routing.

 

Thanks for the response.

Hi,As of now on ACE there is

Hi,

As of now on ACE there is no way to insert client IP. It's only for HTTP and that as you said works like a charm already:)

Policy based routing on server or changing the default gateway of servers to ACE would be the way forward unfortunately here.

Let me know if you have any questions.

Regards,

Kanwal
