Bug #5621

Updated by Chris Buechler over 3 years ago

Issue 1: Multiple dhcp6c processes https://redmine.pfsense.org/issues/5297 introduced a new ppp-ipv6 helper script. I think this broke dhcpc6 for me on one interface issue, leading to broken IPv6 connectivity
Issue 2: Issue 2: Random interface identifiers
PPPoe; when interfaces connect at I boot time

my system, there appears to be a race conditon where both rc.bootup and the new ppp-ipv6 script attempt to dhcp6 configure the pppoe interface. This results in dhcp6c being started twice, and the responses generated by my ISP get ignored with an "XID mismatch" message. It seems checking the pid file has an inherent race condition that is kind of hard to fix.
