L4 profile

If i create an L4 profile for my SMTP servers can i still do loadbalcing .

 

The require is not to have any SNAT since the reverse traffic from the SMTP servers will be routed back to another VIP using a persistent route

    For the traffic Originating from the backend servers i will have a different VIP which needs to be pointed to so someservers on the Internet . The present situation i have default route pointing to the Internet . If i added persistent routes for those servers in the backhand servers will it still reach F5 VIP Please advice

     

  • Hi abi,

     

    I think your backend servers have have internal self ip as default gateway or is it some other way . This depends on your network setup if you need source NAT or not . This will ensure that outbound traffic leaves F5 . then you have to create wildcard VS with destiantion 0.0.0.0/0 to any kind of outbound traffic . use fastl4 profile .

     

    try with this if not works , enable loose intiation and close in the fastl4 profile .

     

    Thanks

    Am not doing any source natting here , so if am creating a VIP with destination 0.0.0.0 in case my backend servers would have the default gateway of my VIP
