Will there any conflict if the SNAT address same as one of the virtual server?

Hi Sammo,

 

using a virtual IP as a SNAT is fine from my perspective.

 

I.e. I´m using it typically to SNAT outgoing mail.

 

As the receiver will probably do a reverse lookup it has to match one of the IPs the MX records for the sender domain resolve to. This way you lower the risk to get classified as a spammer.

 

Inbound mail is handled by virtual servers using the same IP.

 

As Brad already wrote, the virtual server is using a state table.

 

I can imagine conflicts with protocol like SIP using UDP as transport with fixed ports for source and destination.

 

Thanks, Stephan
