Small Network with VPN and Multiple Switches

I'm trying to connect a VERY small network with 10/100 switches. I've been having a few problems. I have a sonicwall plugged into our dsl line. The LAN port on the sonicwall is plugged into a Linksys switch. Computers plugged into the same switch can access the internet. There's another switch plugged into the first switch. computers on the second switch cannot see the internet or computers on the first switch. I have a strait cable from the uplink on the second switch to a regular port on the first switch. can anyone tell me why my network doesn't work?
 
"There's another switch plugged into the first switch. computers on the second switch cannot see the internet or computers on the first switch. I have a strait cable from the uplink on the second switch to a regular port on the first switch."

You need to use a crossover cable between like machines/hardware...switch to switch, computer to computer... Hewissa

I don't know if you know how to make a crossover...but what you need to do is:

End 1 (looking down, clip at bottom)
wg - g - wo - bl - wbl - o - wbr - br

End 2
wo - o - wg - bl - wbl - g - wbr - br

U shouldn't need a cross-over cable switch to switch, that's the purpose of the uplink port on hubs and switches.

On switches/hubs the uplink port is usually one of the end ports and have a little selection switch next to it, to select between using it as a normal port or 'Uplink' port. I would check this switch is in the correct position.
I have found this to be often the source of a lot of miscommunication, as it is usually quite easy to operate these selection switches accidentally when messing about with hubs/switches.

Logically, I would connect from the 'Uplink' on the first switch (the one with the DSL modem connection, etc) to the regular port
of the second switch - not the other way around as this gentlemen has done.

I also assume that all the computer are set to DHCP and must be getting their IP address from somewhere, if so where from???????
 
guestgulkan, yes you are correct, but I have found that in tight situations the crossover is the sure fire way to connect like devices. When in doubt, watch the "Link' light on the switch/hub..

To take your line of thinking further, don't DSL connections require some sort of authentication? Usually the DSL router supplis that information, and service DHCP requests for the internal network. bjgrem, how is this resolved?

I would setup the netwrok, and maybe guestgulkan would agree, Wall>Modem>Router> Switch & Switch simultanoiusly. fore go ICS and let the router do the NATting. Hewissa

I should of mentioned he is better off buying a DSL router. lol

I did want to ask bjgrem where he wanted the VPN part to fit as his header suggests... Hewissa
