I have my OpenIndiana box providing wan/lan routing with firewall/nat.
I was having some really slow wan performance so I started digging in.
The performance issue was a compromised user account and a machine on
the internet downloading everything from the account, pegging my upload
bandwidth quota.
However, in my investigations, I've noticed a few things that was
wondering about...
Using snoop, I'm seeing a steady flood of ARP request broadcast from my
ISP. As I only have one IP address/MAC allowed does it make sense to
filter out the "not-for-me" requests or doesn't it really matter? Is
there even a way to do this without breaking the WAN-side?
The second question is that I noticed that Avahi has bound itself to
both my WAN and LAN nics. Is there a way to limit this to the LAN nic?
Does mdns have a similar issue? I discovered this by running "bssh" and
seeing the service both on my bge0 (WAN) and bge1 (LAN) nics.
I know that these are not necessarily OpenIndiana issues, but I haven't
been able to google anything useful on these topics. I was hoping that
I could get some insights here.
Regards,
Gary
