Description:
I use FreeBSD as PPPoE dialin server. The configuration is very simple pppoe: enable pap disable chap allow mode direct set mru 1492 set mtu 1492 set speed sync set ifaddr x.x.x.254 x.x.x.225-x.x.x.250 255.255.255.255 set dns x.x.x.1 enable dns accept dns set timeout 3600 enable lqr echo set lqrperiod 15 set echoperiod 15
There was no problems with this configuration in 4.9 and 5.2.1 branches. But
when I
have upgraded to 5.4 - ppp began to assign duplicate ips to clients!!! So,
clients
are stop working. Gleb Smirnoff explained that problem is with CARP
implementation
where some check for duplicating ips was removed from kernel. But this makes
/usr/sbin/ppp ip-pool feature useless, and even this is regression!
Now we can not use ppp without RADIUS (which should support of ip-pool
feature itself).
How-To-Repeat: Try to make ppp dialin server with 5.4 and connect many clients to it Fix:
Really don't know how. But IMHO we should introduce some option like (disable
carp)
and implement duplicate ip checking in ppp code.
