[Serusers] forward() and t_relay() differences

[Michael Shuler]

Thanks, I already read that.  What I was concerned about was more of if they
modified the SIP message differently before being sent.  For example I have
a layer 4 switch in front of 2 SER servers which runs a virtual IP of
198.88.216.84.  The real servers ser0 and ser1 have IP's of 198.88.216.87
and 198.88.216.89 respectively.  The problem I am having is that when I run
2 SER seems to get confused when a gateway starts talking to ser0 while a
client is talking to ser1.  Since the layer 4 switch is doing reverse NAT so
all traffic coming from the 2 ser servers appears as 198.88.216.84 this
causes a problem when they stick themselves in the Via line as their real IP
and not as 198.88.216.84.  Is there a way to override that?  Is t_relay()
what is causing the weirdness?  By using forward(uri:host, uri:port) inplace
of t_relay() will it break anything (I am not checking the status of
t_relay() on return)?
