Hardware load balancers are another options, depending on your budget.
What training class were you talking about?

Hi Rodney and thanks for your reply, things starting to get clearer now,
info
below should clarify a few points...
Your reading is correct, I have never tried with different subnets. How
can
you really do this? What I mean is, with one NIC and two IPs, how can
they
really be on different networks? Unless I am reading your post wrong, I
believe you have VIP = something like 128.128.128.128 255.255.0.0 and Web
Nic 192.168.0.1 255.255.255.0. Is that correct?
Yup that's it, just the other way around with the VIP having the
255.255.255.0 and the NICs 255.255.0.0, that's how it seems at the moment
anyway and the convergence goes through fine on NLB Manager. Logic was
that
the website IP would be the VIP (which is how it is now) and the NIC IPs
would handle the Heartbeat traffic without needing to use 2 more
ISP-assigned
IP addresses...
Incorrect, can I ask where you saw that? The NLB convergence traffic goes
across the NLB Nic and only that NIC, and it can't be configured or
changed.
I'll try find the link to the thread where someone else asked about it but
there's a few articles I found via Google saying about using a "public"
NIC
for the incoming requests and a "private" one solely for NLB heartbeat
traffic - did seem a bit odd to me at the time as couldn't find any
mention
of it in Technet or any NLB documentation!
Whatever you do, don't give us the real IP here, ok. You know this is a
very, very bad idea. So if you take it one step further, the web site
does
not have firewall protection. Did you turn off Anti-Virus protection too?
:)
Fix this ASAP!
Yup, very very bad idea - was one of the things I always wondered on the
old
web server how it didn't get hacked - just pure luck I guess!
I would agree with you and fix it ASAP!
Remember the hearbeat is on the NLB Nic.
Gonna put the 2 web server nodes' NLB (Internet) NICs in a VLAN and
connect
that to the Internet through the firewall I was setting up today asap!
Wait, are you saying the NLB machine is not the web server? It just
forwards
packets to the real web server? Router? More like have the firewall do it
:)
NLB Machines are the web servers running IIS, just wondering the best way
to
forward the requests on from the firewall as I can see port forwarding but
no
way to forward, say, a request for an Internet IP to an internal 192.x.x.x
one. Reason I ask is because most of the diagrams I see have the web
server
on the internal network so the request must be forwarded to it somehow?
It's the IPCop packet-based firewall system http://ipcop.org - maybe it's
just the port forwarding I need to do, got a feeling a post in the IIS
Forum
might help clear things up on the best way to have the web server setup :)
The web server doesn't hold any data though, that's on a NAS appliance on
our internal network, hence one NIC used for communicating with other
servers
and one for the internet connection.
There's such a good clustering \ NLB training course being offered at the
moment that would fill in all the niggling questions but with our current
(lack of) budget I'll just have to keep learning through Technet,
Community
Forums and clever Google searches :)
Thanks again,
Gerrard
