Cisco Routing 5505 Help Part 2

Continue question (part 2)
https://www.experts-exchange.com/questions/22025225/Cisco-Routing-5505-Help.html?qid=22025225

I currently have a CISCO 5505 with a RSM.  I have 4 VLANS
100  10.10.10.1_net  Ports 2/1-8
200  11.11.11.1_net  Ports 2/9-16
300  12.12.12.1_net  Ports 2/17-24
999 192.168.254.1_net Ports 3/1-22

My ISP router/Gateway is set for 192.168.254.254

I want to be able to have any device in any of the four Vlans route to EACH OTHER and OUT to the internet using the 192.168.254.254 of my ISP router which I can put in any port or create another vlan.  Unfortunately, I don’t have clue on what I am doing.  I am totally new to Cisco.  

I have made great progress with others (Thanks Don!!) and I am almost there.  I found a few issues


=============
CURRENT ISSUE
11/29/06
Troubleshooting
==============
Any host in the 192.168.254.x (vlan 999) can NOT access any host in any other vlan.

Host as 10.10.10.5 can access internet (192.168.254.254) and ping 192.168.254.110 and 11.11.11.5
Host as 11.11.11.5 can access internet (192.168.254.254) and ping 192.168.254.110 but not 10.10.10.5
Host as 192.168.254.110 access internet (192.168.254.254)  and only ping 192.168.254.x
Host as 12.12.12.5 have not tried yet




==============
Here is what I have done
==============

On the RSM

enable
config ->  terminal

Router(config)#

access-list 1 permit any
ip nat inside source list 1 interface vlan 999
int vlan 999
 ip address 192.168.254.1 255.255.255.0  (the isp router gateway is 192.168.254.254)
 ip nat outside
int vlan 100
 ip nat inside
int vlan 200
 ip nat inside
int vlan 300
 ip nat inside

It's because the VLAN 999 interface is defined as an "outside" interface in NAT. Usually, the hosts are all connected to "inside" NAT interfaces and the only thing connected to the outside is the link to the internet.

Can you move those devices to another (or new) VLAN?

I was thinking it was due to the nat.  Even after I did a IP NAT INSIDE on VLAN 999 I still had the same issue (could not get to the internet to be expected).  

Even though I would guess vlan 999 would have issues going back and forth. What I thought was strange was Vlan 100 and 200 that are inside in the same switch.

Host as 10.10.10.5 can access internet (192.168.254.254) and ping 192.168.254.110 and 11.11.11.5

999 192.168.254.1_net Ports 3/1-22


 The 5505 is only in use 20-30% of the time in the lab.  I was hoping to avoid creating another vlan then changing the internal IP of the ISP router when the 5505 was online.   Normally there is only 192.168.254.x hosts in to a hub that goes to the ISP connection.  I was hoping to keep the ISP connection up and only flip on the 5505 when needed.

Can you post the config of your RSM?
Once again thanks for your help....

Sure..  Is there an specfic command you want me to run besides sho conf

This is a lab if needed I can blow everything away and start over.  I can send you the step by step I was using from creating the vlans then to the RSM if needed.  I wich you could atach files here..

With this config, all devices should be able to access VLAN 999.

However, VLAN 999 will not be able initiate communications with any other VLAN.

I would suggest creating another VLAN for the end stations currently on VLAN 999.

Don,

  It looks like all the VLANS will route to each other except for Vlan 999 will not route to them (to be expected).  Is there any way to make Vlan 999 inside but have all vlans use use 192.168.254.254 to get out to the internet even though 192.168.254.254 is in Vlan 999?

We use a hub for the 192.168.254.x and I was hoping to keep address range.  I was trying to save the trouble of changing the vlan of the isp and then the ISP internal address (from 192.x to ??) every time we turn on the 5505 for testing.    If the 5505 was on all the time yes,  I would use your suggestion and readdress either the hosts or the internal ISP address.  

The only other option that I am guessing when we use the 5505 is to change the internal ISP from 192.168.254.254 to (Example) 222.222.222.254 then create a vlan for 222.222.222.x and use that for the ip nat outside...  Then when we are done using the 5505 flip it back.

Let me know if there is a way?

Hmm..  Well the lab stuff is normally on a standalone connection (HUB) in to the back of the DSL Gateway using 192.168.254.254 as the GW.    If I left the 5505 on then creating another vlan just for the ISP connection would be no issue.


  Then to make vlan 999 normal I should do a
Router(config)#int vlan 999
Router(config-if)#ip nat inside

For example when I do this a hosts as 10.10.10.5 drops ping to 192.168.254.110

This should just be a normal vlan now right?  The RSM should now route to it?  What else would I need to change/redo?? To get this to work.  

Thanks Again!


My screwup.  I had the GW wrong on the 192's  
Thanks Don you been Great!!
