Hi Kevin --

 

 

With a default SNAT in place, the traffic through a forwarding VS would be SNAT'd.

 

 

If your server addresses are routable out to the remote syslog server, and UDP is the transport protocol, I think you could configure as follows to preserve source IP even with a default SNAT configured:

 

 

Virtual server

 

- Dest: :514

 

- Type: Standard

 

- Proto: UDP

 

- VLAN: Enable on

 

- Address translation: Enabled

 

 

Pool

 

- Members: :514

 

- Allow SNAT: No

 

 

HTH
