Description r00t440 2006-09-29 08:16:40 UTC

Since the rp-pppoe package is already deprecated, and that baselayout is suggesting to use the better PPPoE module that comes with net-dialup/ppp; it would be better if there will be a nice warning in net.example stating an issue about MSS Clamping followed by a recommended iptables rule.

The comment should be related to *all* ppp connections and it should look like this:

#WARNING: if MTU of the PPP interface is less than 1500 and you use this machine
#         as a router, you should add the following rule to your firewall
# iptables -I FORWARD 1 -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu
