Newer Version of the dhclient-script
-
Any news, regarding this topic?
-
Will this Issue be fixed in the final version?

I second the request to update the dhclient-script!
Everyone using T-Home IPTV in Germany is going to have issues if its not updated…
To clarify this problem:
T-Home is using vlans to seperate Web and IPTV traffic. The Web traffic is using PPPoE on Vlan 7, the IPTV traffic is using dhcp on Vlan8.
IPTV is using unicast for the first 10 seconds of the stream and then switches to multicast which is working very good with the new igmp proxy(which is still spamming the main systemlog making it unusable btw!!!)The problem which is fixed by the new dhclient script is that the old script sets a gateway to 255.255.255.255 which is useless and causes the first 10 seconds of unicast to fail which in turn makes switching channels very slow because the STB has to wait for the multicast to begin(1-2 seconds...)
This is a packetcapture for the iptv interface dhcp reply:

With the original script i got this for the Interface in

Name Interface Gateway Monitor IP Description ----------------------------------------------------------------------------------------------------------- GW_OPT3 IPTV dynamic dynamic Interfaceopt3dynamic gatewayMaybe this informations is useful for you…
Both scripts however create the same routing entrys so this is aparently not a routing issue…:
-
push
-
Will this Issue be fixed in Version 2?
I think with the logs and the explanation inside this thread the problem is reasonably specified.
But if you need another tests/logs, I will give it to you.
Thx!

Its not a dhclient issue.
Try this https://rcs.pfsense.org/projects/pfsense/repos/mainline/commits/5766add89187bf47c225f67697e37ca25b0dbc71 or wait for the next snapshots. -
sorry, this doesn´t fix it:
I tried this Build:
2.0-RC1 (i386) built on Wed Apr 6 11:10:23 EDT 2011
Your changes are included in this Build:
if [ "$new_ip_address" = "$router" -o "$router" = "255.255.255.255" ]; then $ROUTE add default -iface $interface echo $ROUTE add default -iface $interface | $LOGGER # NOTE: Do not activate this for all ones address since pf(4) will try to forward packets to it. if [ "$new_ip_address" = "$router" ]; then echo $router > /tmp/${interface}_router fi else $ROUTE add default $router echo $ROUTE add default $router | $LOGGER echo $router > /tmp/${interface}_router fiBut for the Interface I still got:
System: Gateways GW_OPT3 IPTV 255.255.255.255 255.255.255.255 Interfaceopt3dynamic gatewayand I got the same Problems…
-
Can you remove the /tmp/*_router and try dhclient or Save button on the interface page and see if you will get the same?
Maybe making sure that a remnant file is not causing issues.Otherwise something is not matching in that if statement.
-
Sorry, no difference…
after removing the *_router files in /tmp and renewing DHCP-Lease GW is still 255.255.255.255

Can you try by changing that section from
if [ "$new_ip_address" = "$router" -o "$router" = "255.255.255.255" ]; then
$ROUTE add default -iface $interface
echo $ROUTE add default -iface $interface | $LOGGER
# NOTE: Do not activate this for all ones address since pf(4) will try to forward packets to it.
if [ "$new_ip_address" = "$router" ]; then
echo $router > /tmp/${interface}_router
fi
else
$ROUTE add default $router
echo $ROUTE add default $router | $LOGGER
echo $router > /tmp/${interface}_router
fito
if [ "$router" = "255.255.255.255" ]; then
$ROUTE add default -iface $interface
echo $ROUTE add default -iface $interface | $LOGGER
# NOTE: Do not activate this for all ones address since pf(4) will try to forward packets to it.
elif [ "$new_ip_address" = "$router" ]; then
$ROUTE add default -iface $interface
echo $ROUTE add default -iface $interface | $LOGGER
echo $router > /tmp/${interface}_router
else
$ROUTE add default $router
echo $ROUTE add default $router | $LOGGER
echo $router > /tmp/${interface}_router
fiAlso please check which of the messages from the above are in your system log.

Hi,
I changed the script to:
for router in $new_routers; do if [ "$router" = "255.255.255.255" ]; then $ROUTE add default -iface $interface echo $ROUTE add default -iface $interface | $LOGGER $LOGGER "TEST1" # NOTE: Do not activate this for all ones address since pf(4) will try to forward packets to it. elif [ "$new_ip_address" = "$router" ]; then $ROUTE add default -iface $interface echo $ROUTE add default -iface $interface | $LOGGER $LOGGER "TEST2" echo $router > /tmp/${interface}_router else $ROUTE add default $router echo $ROUTE add default $router | $LOGGER $LOGGER "TEST3" echo $router > /tmp/${interface}_router fiYou see, for testing I added $LOGGER "TEST1", $LOGGER "TEST2" and $LOGGER "TEST3" in each If, elif and else block.
But in System-Log i can´t see any TEST1, TEST2 or TEST3

I made a fix that will be in latest snapshots which should fix this by not having a gateway declared from dhcp and so no PBR will be done from pfSense and routes will be followed.
Please test latest snapshots and let me know.

This fixed my issue!
