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.
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
