HybridKempers hakkelende internetverbinding

[huub]

HybridWatertoren3, internet vanaf Kempers:

HybridKempers# fetch -vvv -o /dev/null http://www.nu.nl
scheme:   [http]
user:     []
password: []
host:     [www.nu.nl]
port:     [0]
document: [/]
---> www.nu.nl:80
looking up www.nu.nl
connecting to www.nu.nl:80
(en hangt)

en soms wel succes:

HybridKempers# fetch -vvv -o /dev/null http://www.nu.nl
scheme:   [http]
user:     []
password: []
host:     [www.nu.nl]

De bandbreedte van de interlink (iperf van watertoren naar kempers) is 8 - 14 Mbps;

Uiteindelijk is de oorzaak door Rick gevonden:bij Watertoren3: op de externe interface staat ook een lokaal ip en in NAT roundrobin.dus soms wel en soms niet internet.
Firewall pf.hybrid.conf aangepast op watertoren3. Dus Kempers en Kudelstaart weer internet OK. Nog wel ook andere nodes aanpassen.
