[f-nsp] load balancing remote smtp servers

[dalton]

Hi,

I have a foundry serveriron XL

I am try to configure a vip to load balance postini mailservers (which act as
relay hosts for a local smtp server here).

Here is the problem:

It works fine if the server remote-name allows icmp (l3 check)
However, postini is blocking icmp.

Is there a way to turn off l3 healthchk and use only l4?

I have the remote-name configured as such:

server remote-name postini1 x.x.x.x
 source-nat
 port smtp
 port smtp l4-check-only

but its still failing out.

am i missing something obvious here?
