Questions about network layout
Hello all, thinking and reading of networks always make me think, and I have some questions, let me draw a sketch of the network I have, and then I'll put the questions:
[Internet]--->[Linux Bridge]--->[Windows 2003 Server]--->[D-Link Switch DES 1024D]-->Hosts
This is the big layout, now, the Linux Bridge has 3 NICS, two for making the bridge between the internet and the w2k3, and one for network management and squid.
The Windows 2003 Server handles DHCP and DNS, altough I don't like W2k3, this is necessary for the current IP Phone we have here that just don't work with the Linux NAT, so this is way this network is so messy.
Now for the questions:
1) The D-Link Switch is a basic 24 ports switch, is it possible to make for instance 12 ports on the switch to receive an IP like 10.0.0.0/24 and the other 12 ports receive 10.0.1.0/24? With Linux or Windows, really, I just want to know if it's possible. Remember that this Switch is a "dumb" Switch, does not have any administration on it.
2) Is it possible to build VLans with the Linux bridge? Or for this I would really need the Linux to actually handles DHCP et all?
3) Also, let's say we put a Wireless router, just to route internet and not intranet stuff.Eere should it be best? Right attached on the Windows 2003 with a different NIC to make a physical different connection, and then let W2k3 handle this, or on the Linux Bridge making it part of the bridge?
Please see that the Network layout can change (ie, putting the linux bridge as DHCP and DNS servers, and letting the W2k3 just for Active Directory et all), but it would be best if it didn't changes, because of the god forsaken Ip Phone that can't work fine with the Linux NAT.
Thanks a lot!!!

networks(4) File Formats networks(4) NAME
networks - network name database SYNOPSIS
/etc/inet/networks /etc/networks DESCRIPTION
The networks file is a local source of information regarding the networks which comprise the Internet. The networks file can be used in conjunction with, or instead of, other networks sources, including the NIS maps networks.byname and networks.byaddr and the NIS+ table networks. Programs use the getnetbyname(3SOCKET) routines to access this information. The network file has a single line for each network, with the following information: official-network-name network-number aliases Items are separated by any number of SPACE or TAB characters. A `#' indicates the beginning of a comment. Characters up to the end of the line are not interpreted by routines which search the file. This file is normally created from the official network database maintained at the Network Information Control Center (NIC), though local changes may be required to bring it up to date regarding unofficial aliases and/or unknown networks. Network numbers may be specified in the conventional dot (`.') notation using the inet_network routine from the Internet address manipula- tion library, inet(7P). Network names may contain any printable character other than a field delimiter, NEWLINE, or comment character. SEE ALSO
getnetbyaddr(3SOCKET), getnetbyname(3SOCKET), inet(3SOCKET), nsswitch.conf(4), inet(7P) NOTES
The official SVR4 name of the networks file is /etc/inet/networks. The symbolic link /etc/networks exists for BSD compatibility. The network number in networks database is the host address shifted to the right by the number of 0 bits in the address mask. For example, for the address 24.132.47.86 that has a mask of fffffe00, its network number is 803351. This is obtained when the address is shifted right by 9 bits. The address maps to 12.66.23. The trailing 0 bits should not be specified. The network number here is different from that described in netmasks(4). For this example, the entry in netmasks would be 24.132.46.0 fffffe00.
