Basically, I want to know if I can set up this Linksys E4200 router the way my Sonicwall TZ210 is setup, I don't know how or why but I can assign the TZ210 one external static IP and it shares that IP with all of the interfaces (all computers hooked up to the ethernet port share the same external IP). The tz210 is also the first thing behind my modem. What I want to do is hook up a switch to the modem so that the switch becomes first thing behind modem and hookup the tz210 to one interface on the switch and this router which is a Linksys E4200 on another interface on the switch but to have the linksys so it shares one external static IP like the sonicwall tz210 does. Is this possible? How do I go about doing this?
Can I assign one static IP to share on this router?

You are on the right track. In networking there is a Network Address Translation (NAT) protocol that does exactly what you described. The one static IP address will have to go on the interface that connects to the outgoing connection. For example on the "WAN" interface on your linksys router and that "WAN" interface connects to your modem and goes out. Once that is established it will share that one static IP address with all interfaces connected to the "LAN" (1-4) ports on your router (these are actually switch ports built into that router). From there you can connect the switch to one of the LAN ports.
Now, another interesting thing here is that Sonicwall. Is that a VPN you have to another site that you may have or if people dial into it?
If you need to have both, best thing I would do is keep the Sonicwall directly connected to the modem since it may act as a entry point for VPN connections to your network. From there, connect the Linksys router to your sonic wall VPN which will share the same IP with anything connected to your LAN portion of the sonic wall device.
so it should resemble something like this: all devices in your network -> Linksys router -> SonicwallTZ210 (with static IP) -> Modem
What you cannot do is have the same IP address configured on both sonicwall and linksys devices and connected to the same network with a switch to physically allow it. That will cause one of the following:
IP address conflict where neither works
IP address conflict where the first device gets the IP and second one to get detected by the network is just screwed.

I'm glad I am on the right track and you are understanding my question. However here is the issue with the sonicwall. I want to be separated from the sonic wall. My friend and I each have our own "servers" which in the past were both connected to the Tz210. Long story short, the tz 210 stops giving out Internet every day at 6pm for about 30min or until it is manually resetted, it also disconnects people from minecraft or ftp when I am transferring files. Its just a hassle, theres something wrong with it. I know this because the current setup of my network is my server connected to the linksys e4200, which the linksys is the first thing behind the modem configured in bridge mode, and then the sonic wall tz210 is behind the e4200 I believe via the WAN port and I have no disconnecting issues what so ever on my server. My friend doesn't want to have to reconfigure IPs and likes the sonicwall admin panel so he is just staying on it. I understand I cannot have the same IP address, just have a block of 5, 2/5 are usable to assign to some routers or noncomputers. I hope I am being clear and understandable, thanks for helping btw.
