Set mtu on ppp0 device?
I want to lower the mtu setting of the ppp0 device. The pc connects with pppoe. Setting a different mtu on the eth[x] devices is easy enough, but the mtu on ppp0 persists at setting itself at 1492 no matter what I change in /etc/ppp/peers/dsl-provider or /etc/ppp/options.
/etc/ppp/peers/dsl-provider: pty "/usr/sbin/pppoe -I eth0 -T 80 -m 1452 -C [isp] -S [isp]" ... mtu 1452 ... How do I override the mtu on ppp0? (Debian, using the debian rp-pppoe package) |
obviously i am too late
Obviously i am late. But it may help someone.
#ip link set ppp0 mtu 1452 add it to start up script somewhere ppp0 - is ppp network interface inside linux kernel. where 1452 - mtu size actually. To see if you have ppp0 interface do "ip link" I assume that iproute is installed. http://www.policyrouting.org/iproute2.doc.html |
