<font face="monospace">Hi Mark,<br>
<br>
You say the DNS is publishing only one IP for the domain, but one
may change ? If you want, you can PM me the actual domain to see
how the DNS records looks like.<br>
<br>
Regards,<br>

</div>
<div>The GW's have 2 CNAME records which I have no control over.
DR has entries like <a href="http://subdomain.example.com:5061" target="_blank">subdomain.example.com:5061</a></div>
<div>I suspect the issue arises when the CNAMES swap around
resulting in a mismatch.</div>
<div><br>
</div>
<div>Currently I am using this to identify the source of the
message which is probably not the best in terms of security.</div>
<div><br>
</div>
<div>$avp(fd) = "<a href="http://subdomain.example.com" target="_blank">subdomain.example.com</a>";<br>
</div>
<div>if($(ct.fields(uri){s.index, $avp(fd)}) != NULL)<br>
</div>
<div><br>
</div>
<div>Perhaps there is a better way?</div>

<div> <font face="monospace">Hi Mark,<br>
<br>
If a gw is defined via FQDN, that will by DNS resolved
(NAPTR, SRV, A records) when DB data is (re)loaded by DR
module, and used later for such checks. All found IPs
(from DNS) will be stored on the GW.<br>
<br>
How do you specify the GW address in DB and what kind of
DNS records do you have for it ?<br>
<br>
Best regards,<br>

<div>I am using is_from_gw() to match against a group of
gateways specified by DNS names which resolve to
multiple IP addresses but it seems to be failing to
match.</div>
<div><br>
</div>
<div>Is this supported functionality or do I need to do
something else in this case?</div>
