Switch Question

[redman71]

Here is the scenario.
I have a gigabit fiber connection coming in and a cisco 2970 catalyst. I'm trying to bring in a firewall that only has a 100Mbps external port. I've purchased a 1G fiber/copper media converter, however the copper side only operates at 1G. Shouldn't I be able to add in a 10/100/1000Mbps switch that will pass the signal to the firewall? Then add run a straight cable to my catalyst that will be on the trusted side of the firewall? Then everything on the catalyst will be BEHIND the firewall?
HELP!

if returning the current converter is a choice, here are some gig fiber converters that allow 10/100/1000 copper connection.

I tried to remain child-like, all I acheived was childish.

If I understand, you have fibre coming into the building as your 'untrusted' network?. Have you considered using a Vlan to group the fibre port that comes in at 1gb and one ethernet port at 100mb. Plug the Firewall 'untrusted' port into the Vlan ethernet and the 'trusted' Firewall port into another 'regular' ethernet port that the internal 'trusted' network can then see as the default gateway to get out. I haven't used a 2970 but it sounds possible?.
