|
for the first time i got this in my syslog from last night
possible DNS-rebind attack detected: rrx68giz-7cfe4b3e3edde72856fc8ee1080e4a6079fc55f2-mob.d.aa.online-metrix.net
possible DNS-rebind attack detected: rrx68giz-f026ebfb2c019f32ef092f5ef5ca73eb7f85edea-mob.d.aa.online-metrix.net
so i have a few questions:
how reliable is no DNS rebind settings in DD-WRT?
shall i use those lines instead:
iptables -I INPUT -s `nvram get lan_ipaddr`/`nvram get lan_netmask` -d `nvram get wan_ipaddr` -j DROP
i believe or they gonna brick my router as it happens before or im wrong and they are ok to use....
and last thing is how i can find the IP range of the attack source or if anyone know's it please share ??
my router is R7000 with 30645M Kong if that makes more sense..
i use DNSMasq, Local DNS, and i run Ad blocking script + IPTables firewall stuff _________________ Atheros
