Hello,

I suggest you the 800 series routers designed for SOHO, but even big companies use them on offices.

You can read the datasheets on the page http://www.cisco.com/en/US/products/hw/routers/ps380/ and you will see if it is that what you want.

Depending on the software you can have very high services and also excellent firewalling.

For a 2Mb internet connection, any of hte ISR routers should do fine. Go for the 1800 series. You have the choice of wireless or not (although that doesnt seem like it would be an option with 250 computers).  It will also allow you to expand in the future should you need more options (WAN optimization, accelerated VPN etc).

I would suggest you look at either of the two low end families, 800 or 1800.

Do you need VPN connectivity (either from your site to another site or from employees homes into your site) or Wireless?

Either will handle up to a 100 Mb connection. speed within your LAN will depend on your switches, not your router (unless you have different subnets and this is the only router present). Again, which model you need depends on many factors. if you plan on having VPNs, and how many. What features you will need. etc. From the sounds of it, you should go with the 1801. Very basic, but room for growth.

Any router will handle a 2Mb connection from your ISP. All of the routers will handle VPN connections. the only cost will be if you want to improve the VPN performance. If you are looking for the cheapest option, get a Cisco 851. 100Mb WAN. 100Mb LAN. up to 5 VPN tunnels.

Only downside to an 851 is that you're limited to 5mbps throughput. If you ever got a faster connection the router would be a bottleneck. An 871 has the same configuration but is rated at 12mbps.

I would recommend Cisco ASA 5510 which will handle the number of your computers. ASA 5510 is the firewall and is cheaper than router of same capacities.

The 851 will be adequate for a 4mbps connection.

I agree with donjohnston, the 851 will be able to handle 4mbps without any issue.  However you may want to go with the 871.  It has a few more advanced features, like IPS, for only about USD$100 more.

the 851 may not be adequate depending on how your lan is set up. If you have a LAN with GIG speeds and you have multiple subnets that need routing via the 851, it then becomes the bottleneck. I have a feeling however that your network is flat so as I said, the 851 would be your cheapest solution.

I have a 831 that will handle up to 10mb, with 100mb internal switch that we used at one point to connect 40 VPN tunnels concurrently. The IOS is 12.4(12c). I'm selling for $90 with $10 shipping if you want it, or I have a SOHO 90 with the same specs (but software ipsec) for $80

>             I have a 831 that will handle up to 10mb

While it may have a 10mpbs interface, the routing engine can only move data at 4.35 mbps.

Oh,
also my 830 router does pass 10 mb. When I do a download from Sourceforge, it hits 1080 kbps and goes no higher, but stays there. Not tried the soho 90 with that test though.
