Hey there,

I have a Internet--netgear router--2801--3560---client

Switch handles intervlan routing and 0/48 is routed to 2801 for internet.

from client, can ping my vlan, clients on other vlans
From client, I can ping switch routed port to router
from client, I can ping 2801's outside NAT int to netgear 192.168.0.224
from client, I can ping netgear LAN 192.168.0.100
from client, I can't ping internet or IP's

From switch, can ping netgear LAN
From switch, can't ping internet

From router, I can ping From router, I can ping clients on my vlans

I'm reading... but I thought I'd spit out my configs and get the tek-tip army on the job.

Here are my configs for router and switch

Hi
Did you get the DHCP working?I was expecting to hear from you in your other post.
Can you post a "show ip nat translation" from the router?
Try to putting a workstation directly behind the router to see of NAT is working.
Change the default route to ip route 0.0.0.0 0.0.0.0 fastethernet0/1.
If you stick with me,I will get this up and running.I have done similar configs in the pass.
Regards
 
Hello
Before you do any of the above!Try putting a default route on the switch.

ip route 0.0.0.0 0.0.0.0 192.168.49.1

or

ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/48

Regards
 
Minue,

You are the best man. Welcome to my newest problem thread! I did get dhcp working!! I moved all the dhcp stuff to the switch and now it serves the info to clients on any vlan. But I could never get past the 192.168.0.100 (netgear router) and onto the internet.

My clients are being given by dhcp:

IP: 192.168.52.1
Mask: 255.255.255.0
Gateway: 192.168.52.200
DNS: 62.4.16.70
Wins: 192.168.58.1

But I guess you can see that by looking at my pools in the switch :)

I tried adding both routes but still can't get out. At the moment, my client can ping, through the switch and router, to many hosts on the 192.168.0.x network but can't ping 192.168.0.100 (the netgear). The netgear returns pings only to the 2801 and my coworkers PC on the 192.168.0.x network.

I think it's so strange how my client can ping through all my gear to clients on the 192.168.0.x but cant get past that!
 
Post the topology---something is either not NATting or NATting when it's not supposed to be...something along those lines...

Thanks Burt,

I started from scratch and now it works! I'll bet you were right thinking NAT was't working.

Now I have dhcp server on the switch sending clients the proper info to talk to other vlans and getting them onto the internet.

Yeah baby!

Thanks guys!

Next stop:

1)Arping IP addresses to Aironet access points running PoE.
2)VPN clients and or VPN router connection.
3)See sunlight one of these days.
