New to irules

Hi Guys

 

 

I have inherited an F5 configuration, with the following irule configured

 

 

when CLIENT_ACCEPTED {

 

if {[IP::addr [IP::client_addr]/23 equals 10.49.50.0]} {

 

snat automap

 

}

 

}

 

 

This does not seem to applied anywhere, and some of the guys here believe that this is applied as a gloabal configuration. Is it possible to have this set as a Global Irule, without selecting this against any VIPs?

 

 

Please let me know, i've never used irules before, so not sure on the configurations

 

 

Thanks

    You could certainly have snat automap applied to a VIP but this is an iRule and would have to be applied in the iRules section so no, not globally applied.

    Thanks Chris, so just to confirm for myself. I would need to add this irule to a resource on VIP for it to work?

    Correct...if you want the automap to be specific to that network. If the VIP has "Automap" selected under "SNAT Pool," then it will automap all traffic, not just this range.
