There isn't enough information here for a coherent bug report, and it doesn't look like a new or unique issue that we can do anything about. Post on the forum to discuss your problem first.
DHCP Relay is unlikely to work with IPsec when run on the firewall -- run DHCP relay on your local L2/switch instead.
DHCP Relay isn't going to work on PPPoE (which is what your error is) -- that isn't something we can fix, it's a limitation of the DHCP relay daemon itself.
DHCP Relay attaching to interfaces it probably shouldn't has already been solved in #9466

Mar 12 12:34:24 dhcrelay exiting.
after that i default code is as below
foreach ($srvips as $srcidx => $srvip) {
$destif = guess_interface_from_ip($srvip);
if (!empty($destif)) {
$dhcrelayifs[] = $destif;
}
}
$dhcrelayifs = array_unique($dhcrelayifs);
/* fire up dhcrelay */
if (empty($dhcrelayifs)) {
log_error(gettext("No suitable interface found for running dhcrelay!"));
return; /* XXX */
}
$cmd = "/usr/local/sbin/dhcrelay -i " . implode(" -i ", $dhcrelayifs);
if (isset($dhcrelaycfg['agentoption'])) {
$cmd .= " -a -m replace";
}
$cmd .= " " . implode(" ", $srvips);
echo $cmd;
die();
mwexec($cmd);
unset($cmd);
and then i just added unset for pppoe
foreach ($srvips as $srcidx => $srvip) {
$destif = guess_interface_from_ip($srvip);
if (!empty($destif)) {
$dhcrelayifs[] = $destif;
}
}
$dhcrelayifs = array_unique($dhcrelayifs);
/* fire up dhcrelay */
if (empty($dhcrelayifs)) {
log_error(gettext("No suitable interface found for running dhcrelay!"));
return; /* XXX */
}
unset($dhcrelayifs[1]); //<-------------
$cmd = "/usr/local/sbin/dhcrelay -i " . implode(" -i ", $dhcrelayifs);
if (isset($dhcrelaycfg['agentoption'])) {
$cmd .= " -a -m replace";
}
$cmd .= " " . implode(" ", $srvips);
echo $cmd;
die();
mwexec($cmd);
unset($cmd);
the command out put like below after that dhcprelay does work
/usr/local/sbin/dhcrelay -i igb2.64 -a -m replace 10.16.16.30 10.16.16.29
