[HIDDEN FEATURE] 7.380 Kernel mode PPPoE

Hi All,

in 7.380 we introduced kernel mode PPPoE as a "hidden feature". This reduces the CPU usage of PPPoE on high bandwidth connections (16 Mbit/s and more) significantly.

Kernel mode PPPoE can be enabled on command line (as root) via confd-client.plx using the following command sequence:


confd-client.plx
OBJS
interface
pppoe
REF_ID of interface (press TAB for list)
kernel_mode=1
write

The success of this operation can be verified by calling "ps x |grep pppoe" on the command line. The output should contain the string "/usr/sbin/rp-pppoe.so".

Depending on your feedback, we may change the default config to kernel mode in a future version. So please post your experiences here.

Regards,
Daniel

Just some feedback about that change:

No problems since 5 days now that this is active on my ASG120...

what about a check box in the ASG UI for pppoe interfaces to make it disabled if needed... ? but make this default...

thx

What BuBu said, why not just make this a checkbox option?

Kernel mode is going to be new default (well, not in 7.400) with fallback to set to old behaviour if there don' t show up any problems (As already written in first post).

Note: Ensure your PPPoE Interface has the correct MTU size of 1492 and not 1500
before enabling kernel mode pppoe.

Otherwise the generated iptables rule setting the MSS size of forwarding TCP connections
has the wrong size and some sites, e.g. microsoft.com will not work!
