Network layout suggestions

I am in seek of some suggestions on how i should lay out our office network.  This is what we have and what we are doing.

We have six remote VPN locations that all connect to the office router.
We have pptp clients that also connect to the office router.

Inner office behind router looks like this:
Database server - CC processor machine - Call center machine

These are connected to a hub off of the router:
6 Workstations - 1 linux syslog server

Some things that need to be kept in mind:
Remote vpn cities must reach (CC processor machine, Database server, syslog server)
Workstations need to reach (All vpn machines, Database server, CC processor machine, Call center machine)
Pptp clients need to reach (Database server, All vpn machines)

If someone could please give me some suggestions on how to correctly lay out this network, in an effeicent way many thanks will be awarded (plus points).

Maybe I'm missing something, but this sounds like you already have it setup correctly.
A couple of things: I hope you meant switch and not hub. If you meant hub, ditch it and get a decent switch.

To me I diagram it this way:

Internet > Router> Switch>Servers and PC's (in switch)

Your external users should have no problem accessing all the resources on your network.

If this answer is simplistic, could you elaborate further on what you are missing?

bkellyboulderit you are correct it does work the way it is but, ever since i put the linux syslog-ng server in there it has slowed down the network alot, and yes i said hub i know i hate hubs, i will change that out.

what about DMZ for the Database server, CC processor machine and syslog server?  Would it better route the packets if they were seperated in two networks.

Not to me. This sounds like hardware issues, not logical setup. Meaning, I'd worry about that if you were able to saturate a gigabit link, like say a big setup. This does not seem big to me. My guess and most importantly is that the syslog server is generating a lot of traffic, causing the hub to generate a lot of traffic. HUB+TRAFFIC=BAD

When you switch your switch, my guess is this will be a non-issue. If anything it is the cheapest and easiest thing to replace, and is sorely needed. A 16 or 24 port gig switch managed is only $200-$400....  Then I would worry about the next things.... :-)

-k- 24 port linksys sr224 switch has been in place for about a week now.  Still signs of congestion and other weird networking issues.

What causes a machine on the network that has shares on it all of the sudden not show up? "Microsoft Windows Home Editon" (Don't ask why)  Sharing files and for some reason it will just not show up on network.  Checked sessions and no sessions were active.  Can ping and get to it from ip but not name.  After getting to it from ip guess what it shows up.  Is this caused from DNS Cache?  Or wtf?  Same thing happends with our DB/IIS server Type Network name in addressbar of IE and it cannot find it.  Use ip and works fine.

Does that machine have a firewall running? Is DNS and WINS pointed to the domain controller server? I assume they are set in DHCP?
