Ok, so I'm hoping the answer to this question will complete my basic
understanding of vlan setups. I have a system with the following
network device configurations:
-
hostname.dc0: up
hostname.vlan0: inet 172.17.1.1
Lets say I'm setting up vlan devices so that 4 completely separate
subnets' gateways can share same ethernet port on the router. Is it
more appropriate to give the physical device itself an ip address and
then create 3 vlan devices, or to give the physical device no ip address
at all and
Hey everyone,
I've got a really stupid but really simple question. If I have an
openbsd machine acting as an internal router (private IP addresses on
all interfaces) for several subnets that have to share physical ethernet
devices, should I use IP aliases or vlans, and in either case, would
Sorry I should know this but I'm sorta green. If I enable
net.inet.ip.mforwarding on all my routers, should that allow
OS X things like bonjour and iTunes music sharing to work
across the bridge?

anything other than small-scale home use. i'm acutely aware of
that at this point. (the mac decision was someone else's)
anyway, thanks for your time,

Thank you both for your responses. I have made this diagram
clearer because I sort of *am* using the same subnet on both
sides of the bridge... or at least that was my intent, but
obviously the address ranges have to be separate on both sides
of the bridge even though the netmasks need to be the
Sorry just for the sake of correctness:
em0 and em1 are the devices on firewall 2, not en0 and en1...
thats a typo.

Actually I am having a similar problem with an entirely different (I
think) VPN solution. Pings work for me but tcp/ip *returns* don't work.
Sometimes they only fail on the first try, but for some hosts they
never respond.
Two questions, out of curiosity, is this VPN you've set up
Yes, I'd recommend pf. If you've never worked with it before,
the PF section of the FAQ is an excellent starting point.

Sorry I should have read the original more carefully before replying.
For some reason I thought you wanted to filter by source address. PF is
not the way you'd want to go for filtering based on the HTTP GET request.

Greetings all,
Last week I described briefly a problem with *return* TCP/IP traffic
only, across a LAN-to-LAN VPN network bridge, only on the first
connection. I appreciate your responses and so now as you've requested
I have composed a detailed network topology and configuration document
in
Greetings.
Is there a commonly known cause of *return* TCP/IP traffic
to reach but be dropped rather than passed back across a
bridge (ala bridgename.bridge0) but... get this... only on
the first try?
I'd like to get into a detailed explanation of the network
topology I'm working with here but
