Router Suggestion?

[liquidinferno]

Hello, need router, but not sure which one.

Here is config :

Bandwith: 100 megs fiber to converter ( fiber to rj45 )

ServerS:
- Microsoft ISA server
-Webserver
-SQL server
-File server

Olicom Crossfire 32port layer 3 switch.

i need the router so i can plug the bandwith in, take it to ISA and from ISA to switch , from switch to other 3 servers.Probably thinking Cisco 2500/2600 series, but it needs to support 100 meg pipe.Help a brother out.

What sort of fibre is it? If your "converter" is making it into an Ethernet signal, then you just need a high-end switch. Heck, just a computer with a software gateway installed would work.

The Cisco 2500 is a good choice, and don't you mean layer 2 switch? I've never heard of a layer 3 switch as that would imply protocol routing. if you just need to go from fibre optics to ethernet you can just get a converter something like this just be sure you are using the right fibre connectors SC connectors are the most common, but not the only ones in use.

Cisco Catalyst switches, and others from brands like Extreme, are in fact level 3 switches. 🙂 They perform very similar functions as routers do, and in fact Cisco recommends the use of switches as the backbone of a large network rather than routers.

well, what i have is layer 3 switch 🙂 , but either i am stupid or i dont know.. here is the problem i run into, i am trying to plug in the 100 meg rj45 ( I already have fiber to rj45 converter) into a server ( its a MICROSOFT ISA server, two nic's , one for external ip and one for internal) , i connect everything directly to ISA , from ISA to Switch and from Switch to rest of servers ( ISA is domain controller as well as DHCP server) all the DNS records are correct but the rest of the servers do not connect to Internet. So i call our ISP and they are actually saying that if i had router and entered the WAN ip address in router and used one of the rest 5 usable ip's to enter into ISA server it should make everything cool.. I hope this makes some sense.

and maybe i can even make the switch work instead of purchasing router., but i do not have much knowledge about configuring it.

You definitely should not need to buy any other products. How to configure the network though is beyond me, as I have no experience with an ISA server or that type of switch. The ISA server I assume should be configured as a firewall so that it works using NAT since you want to have machines behind the firewall, and it may not be properly doing that.

How much actual throughput do you need? Your link speed might be 100Mb/s, but is that all available to you, or does it bottleneck / shape down the line? A 2600 series won't do 100b/s full-duplex last I checked, certainly not when you turn on a bunch of features.

What do you want said router to DO? NAT? Packet filtering - basic, stateful, serious firewalling? Any dynamic routing protocols?

Details, please.

Ok let me get this strainght, so you have a fiber connection to your ISP, and using the Fiber to RJ45 converter you connect that to the one of the nic (wan)of you ISA server. The other nic on you ISA server (lan) connect to the switch where your lan reside. Your ISA is a domain Controller/ DNS??? Why dont you explain your network more thorough so people can help you easier!

 

[liquidinferno]

I dont need any firewall /NAT/etc, just basic router that will take full 100 meg connection ( and yes i get full 100 meg at all times)............. And on second remark.


HERE IS:

RJ45 from ISP With 100 MEG plugged into ISA server WAN NIC, from ISA server's second NIC (LAN) it goes out to switch, where all the rest of servers are plugged in. But thank you for the help, i actually got it working without the router 🙂
