Prior to installing in a customer site, weīve been running a 4.3R and PPPoE
into a banal Alcatel ADSL bridge, "Home Speed" or somethting, in France as
LAN router/ipfilter firewall. All seems to be running well, but after very
long observation, we donīt like:
1. pinging from an LAN station to the ip of the upstream WAN port, we
observe 5 to 10% ping loss. Itīs ADSL from France Telecom , sh!t is to be
expected.
2. pinging from internet to the FreeBSD ethernet/PPPoE interface, we see
similar ping loss. cool, itīs symmetrical.
3. whatīs disturbing is that from the inside, we sometimes see total
disconnects of 3 minutes or more, where ping just times out 20 times or so,
5 second timeouts. We donīt see these long disconnnects when pinging from
internet to FreeBSD.
4. During these long disconnects, we can sometimes shorten them by
refreshing a website page from the LAN to Internet, ie, it seems that we
can get PPPoE, dead to ping and POP3 mailbox checks, going again by hitting
a website. But, this is not a reliable technique.
We canīt fix the crappy ip over ADSL from FT, but what can we do to prevent
what appears to be long timeouts in the PPPoE to Internet provoked by lost
packets, which renders the FreeBSD solution unuseable.
hereīs our ppp.conf:
set log Chat Warning Alert Error Connect
set device PPPoE:ste0:meidsl
set speed sync
set mru 1454
set mtu 1454
set ctsrts off
enable lqr
add default HISADDR
set timeout 0
set redial 0 0
enable lqr
set lqrperiod 2
accept lqr
#Network Address Translation (NAT)
nat enable no
#nat log yes
#nat same_ports yes
#nat unregistered_only yes
enable dns
