Thank you for the quick reply.<br><div class="gmail_quote"><br>I've noted in the email the result for ping. Ping has no problems. Here is some ping output again:<br><i><div class="Ih2E3d">[root@machine libexec]# ping -c 3 domain.tld<br>

</div>Additionally, if you try using check_icmp instead, it will also tell<br>
you which of the routers along the way is sending the ICMP_UNREACH<br>
message, so you'll know which router you need to reconfigure to get<br>
it to work. HTH<br>
