 Posted: Fri Dec 07, 2012 1:29 pm Post subject: pppoe and mtu [solved] |
 |
|
My home network is configured in the following way:
modem -- eth1 (pppoe) --- eth0 --- wireless network
all wireless clients need to set by hand mtu=1492 to browse internet.
No, I bought a stupid close device which is unable to set mtu (and which does not read option interface-mtu from dhcpd) by itself.
Anyway, this device browses correctly if connected to internet through a commercial wireless router.
what should I do to browse with my device?

Instead of messing with all clients, use this iptables rule on the machine than runs pppoe: | Code: | | -I FORWARD -p tcp -m tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu |
