Hi

 

I'm new in Wan configurations, and I have Cisco 2851 IOS 12.4(3i) we will to increase our WAN connection in 20MB and I need to install a Wan interface to support this, but I do not know what model of interface can I use, I verify in cisco and see the HWIC-1GE-SFP ( http://www.cisco.com/c/en/us/products/collateral/routers/2800-series-int... ) but I'm not shure about this.

And then I need an extra LAN interface to my router with 10/100/1000 speed but I do not find any for this model.

 

I appreciate your help

The WAN interface needed would depend on the WAN media.  Yours is Ethernet?

 

If so, what you might consider is trunking your built-in Ethernet ports to a VLAN capable switch.  Although the 2851 comes with gigE interfaces, it doesn't have gigE perforamance capacity.  (On that, whether your 2851 can deal with 20 Mbps, depends on is the 20 Mbps the total aggregate for all traffic?  If so, the answer should be yes.)
