bridge-nf-filter-pppoe-tagged mtu bug? 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. 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 chage MTU by MSS value in iptables, but unfortunatly. Is it netfilter bug? How to fix it?
