Alright so in my lab, which consist of:
Router - 1921 with 8 port EHWIC
Switch - 3750E-24 port GIG Layer 3
I have two networks I am intervlan routing between....
10.1.1.0 /24 VLAN 2
184.108.40.206 /24 VLAN 3
3750E is trunked to 1921 EHWIC
Router - Routed port 0/0 is outside
Router - Routed port 0/1 is shutdown
When I transfer large files between the two VLAN's between two computers the router does all the layer 3 work between the two vlans. How do I get my switch to do the layer 3 work for intervlan routing between my two test networks. I am not confortable with running my router at 99% while transferring files between networks.
I had it setup so the switch had a L3 port connected to the routers inside interface earlier tonight and the switch was bearing all the load on intervlan routing. That is what I wanted but not using a router behind a router.
I probably do not know what to do past this point but if using L3 switch and a dedicated L3 port and not a trunk I can get what I want however I cant seem to get any port forwarding to work from the router down to the actual PC I want to test out a webserver on.
Here is the L3 setup in case this is the route I need to go and there is a simple fix to get port forwarding to work..
Int gig 1/0/24
ip address 220.127.116.11 /24
int gig 0/1
ip add 18.104.22.168 / 24
aka router behind router but port forward will not work. Seems like a double NAT except the 3750e will not NAT. So as confusing as this is ... what shall I look at to get the switch to bear the load of intervlan routing when connected either way and get port forwarding to work?
