Hi guys.
I'm using "OpenWrt SNAPSHOT r11508-000b7687bc" and hit wierld issue. After router reboot I cannot open any TCP connections from router till re-read sysctl.conf

it looks like system didn't apply parameters from sysctl.conf during boot?
do you have any idea what it could be? or possible MTU issue but my sysctl.conf has anything related to MTU
it's pretty short, just disabling IPv6:
++++++++++++++++++
root@a81m3:/home/sam# cat /etc/sysctl.conf
net.ipv6.conf.all.disable_ipv6 = 1
root@a81m3:/home/sam#
++++++++++++++++++
Thank you in advance.
