CentOs 6.9
I already has cofigured brdge br0:
(user.pppoe)-------(server.brdge)-------(ISP)
So, now I want to filter out IP packets by IP adressess from PPPoE traffic that
passes over the bridge.
Server hasn't local ppp interfaces,only bridge and one management interface.
But. Then I seting up system variables:
bridge-nf-call-iptables=1
bridge-nf-filter-pppoe-tagged=1
User got a problem - Some sites are unable to load and give an error.
If I set variables like that:
bridge-nf-call-iptables=1
bridge-nf-filter-pppoe-tagged=0
or unset both to 0, all of sites working fine.
Seems like MTU Black Hole issure. I tried to change MTU by MSS value in
iptables, switching iptabless off, but unfortunatly.
Is it netfilter bug? How to fix it?</pre>
