Extending Network - I need more IP addresses
« on: March 24, 2006, 03:17:15 PM »
Hey all,

I have been trying to set this up with out consulting the all-knowing, but cannot seem to get it to work.

I currently have a SME Server 6.0.1-01 box that is running pretty well. We have purchased several laptop carts that, if all are connected, would exceed the amount of DHCP addresses available.

My idea is, since the students only use these, to set up another server, segregating their information from say staff and administration. This much I have accomplished. The new sever is SME 7 RC1. But I seem to be fuzzy as to creating a new subnet that is visible to both servers depending on permissions.

I added a new network that I wanted the new server to allow dhcp from. These are the settings from local networks on the SME 6 box:

Network      Subnet mask   Number of hosts Router
192.168.0.0 255.255.254.0 512                    192.168.1.2
192.168.1.0 255.255.255.0 256    
192.168.2.0 255.255.255.0 256                    192.168.1.2


The SME 6 box is the primary server, allowing internet access. The configuration is:

Server Mode servergateway
Local IP address / subnet mask 192.168.1.2/255.255.255.0
External IP address / subnet mask XX.XX.XX.XX (removed for security)
Additional local networks 192.168.1.0/255.255.255.0
192.168.2.0/255.255.255.0 via 192.168.1.2
192.168.0.0/255.255.254.0 via 192.168.1.2
DHCP server enabled
Beginning of DHCP address range 192.168.1.200
End of DHCP address range 192.168.1.255

The SME 7 box would use the SME 6 box as the gateway to internet. The settings for the SME 7 box are:

Server Mode servergateway
Local IP address / subnet mask 192.168.2.1/255.255.255.0
External IP address / subnet mask 192.168.1.3/255.255.255.0
Gateway 192.168.1.2
Additional local networks 192.168.2.0/255.255.255.0
DHCP server enabled
Beginning of DHCP address range 192.168.2.200
End of DHCP address range 192.168.2.250

So I configure a computer to use the SME 7 box as the DHCP server. This works, at least with internet access. However, ibays and printers on the SME 6 box are not accessible. This is where I am stuck.

Any help is appreciated...

Thanks,
Brian Grattan

The reason why your printers and file sharing is not working to your SME 6 box is because your running from an internal to an eternal and all the firewalling stuff is ditching your packets when it hits it.

Something to try...

I know the theory behind this works, but I don't know if it will work in SME's config.

SME 6 box:
Local Address: 192.168.0.1
DHCP Range: 192.168.0.2 - 192.168.1.254
Subnet mask: 255.255.254.0

This will open you up to 2 ranges createing all machines equal and then no need for a second server. If it didn't work, you could just have the second box working as a DHCP server.

1st Server:
Local Address: 192.168.0.1
DHCP Range: 192.168.0.2 - 192.168.0.254
Subnet mask: 255.255.254.0

2nd Server:
Local Address: 192.168.1.1
DHCP Range: 192.168.1.2 - 192.168.1.254
Subnet mask: 255.255.254.0
