SNAT for OUTBOUND SMTP
Hello,
I have requirement for outbound SMTP services. Where servers DFG is LTM which are not internet routable. Im thinking to have SNAT object enable on the VLAN where servers sit , SNAT ips will be the bexternal VIP ips.
But the concern i have is even the servers has communication to some of the internal applications where they need to have original servers ips to process , due to SNAT im assuming we will have issue ,, is there any other way we can achieve SNAT for external traffic outbound and no snat to internal traffic were DFG will be self ip (LTM ).
Outlining requirements as
DEstination Subnets for internal traffic : 10.10.10.10
Servers 20.20.10.10, 20.20.10.11
External vip VLAN 202 :- VIPS ( 30.30.30.10 , 30.30.30.11) internet routable
Selfip for server vlans 20.20.20.10.4 (VLAN 101) i.e DFG for servers.
Thanks, RJ
