The Loadbalancers are using NAT pools, thus if a packet goes into qfe0 the
response packets are expected to return out qfe. This works as tested
combinations of hme/dmfe/gem.
>From a packet sniff: (since the email is longwinded enough I'll paste
relevant details)
snoop on qfe0
ETHER: Destination = 8:0:20:f3:cc:ac, Sun
ETHER: Source = 0:10:58:3:c6:b0,
IP: Source address = 216.34.79.209, 216.34.79.209
IP: Destination address = 192.168.35.3, 192.168.35.3
return packet was found on qfe1:
ETHER: Destination = 0:10:58:4:3d:6c,
ETHER: Source = 8:0:20:f3:cc:ad, Sun
IP: Source address = 192.168.35.3, 192.168.35.3
IP: Destination address = 216.34.79.209, 216.34.79.209
The source address in the above capture is that of qfe0, not qfe1
Solaris 8
QFE patch rev: 108806-12.
Standard driver set. QFE Trunking software not installed
IPMP not turned on
IP Forwarding off on all interfaces
rdisc not being used.. routing information static in /etc/gateways
Ran out of ideas..
