Outbound routing based upon source IP

Wow! I appreciate your testing this as this is very big to a very big project. And I was amazed to get such a good response so quickly. Sadly, I have to claim being dumb with iRules. I tried to setup the second example you gave as it was (to me) the clearest and easiest to understand.

 

 

I created a new iRule and went for a basic test of one translation (if the SNAT address is 62.2.2.10, then use 62.2.2.1 as the gateway):

 

 

class snat_gw {

 

"62.2.2.10 62.2.2.1"

 

}

 

 

when CLIENT_ACCEPTED {

 

set my_gw [findclass [IP::client_addr] $::snat_gw " "]

 

if { $my_gw ne "" } {

 

node $my_gw

 

} else { discard }

 

}

 

 

When I clicked on "Finished", it gave me the error:

 

 

01070151:3: Rule [Test_SMTP_SNAT] error:

 

line 1: [undefined procedure: class] [class snat_gw {

 

"62.2.2.0 62.2.2.1"

 

}

 

 

Sorry for not understanding the basics of iRules yet. This is my first experience with F5s and this issue came up quickly.

 

 

Do I need to add something else to get it to understand the reference to the "class" procedure? Can I add a subnet to my entry (i.e. "62.2.2.0/255.255.255.0 62.2.2.1) so that the entire network will use this default gateway.

 

 

Again, thank you for your help. This is huge for us if we can get it working.
