Help Creating an Irule

Hello all,

 

 

I'm a newbie and i need support to create an Irule to solve a problem that i'm facing

 

 

 

I have two email Servers which have two separate SNAT's.

 

 

 

i have those SNAT's to specific ISP's that is working well but when comes back thru another ISP F5 is reseting the communication.

 

 

 

So i need an i rule that can make the communication comes back to the same ISP of the SNAT.

 

 

 

 

 

EmailGW1 >> F5 ( SNAT from 10.10.1.18 to 201.X.X.X) ||| This communication often comes back thru another ISP and it's reset

 

 

 

EmailGW2 >> F5 (SNAT from 10.10.1.11 to 200.X.X.X) ||| This communication often comes back thru another ISP and it's reset

 

 

 

 

 

Does anyone knows a way to do it?

 

 

 

Thanks in advance for your support!

    Hi Anunes,

     

     

    Are you already using a self IP that's specific to each VLAN but you're still seeing the response come back in another VLAN? If you're not using a self IP specific to the egress VLAN you should try that first. If you've done that and it's not working, you could disable TMM's checking of the VLAN using a database key:

     

     

    b db Connection.VlanKeyed disable
