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 meidsl: set authname mei-ip-n2@adsl-tp2.fsa set authkey something thanks Len http://MenAndMice.com/DNS-training http://BIND8NT.MEIway.com : ISC BIND 8.2.4 for NT4 & W2K http://IMGate.MEIway.com : Build free, hi-perf, anti-abuse mail gateways To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
