If LRO is enabled on the FreeBSD receiver, ACKs are already aggregated
(a duplicate ACK will result in an immediate flush though.)

Our OS cousins over at Linux land have implemented some interesting
behaviour when TSO is in use.
They seem to aggregate ACKS when there is a lot of traffic

they can create the

I think any interface configured with ifconfig_* in rc.conf will cause
an explicit additional "ifconfig up" call from /etc/network.subr.

Hello!
I have a strange task and don't understand how to implement such scheme.
There is a router with 3 interfaces:
IF1: PROVIDER A
IF2: PROVIDER B
IF3: LAN
Clients served via NAT. There are about 15 clients.
Now, what i need to do:
By default all traffic from all clients goes to PROVIDER A
yes, unfortunately it's not well enough for me:((

Steinar Haug, Nethelp consulting,
Sam,
It seems that the distribution includes a directory called db_sample
with some tutorials/examples.
But it also seems that the last release of wide-dhcp is 16 years old...
