Hi Jon, Thanks for this. This makes a lot of sense. I noted taht you said if I use STATIC NAT then I can get rid of the Dynamic NAT/PAT. I am a little stuck on what the Config might look like. Would it just be : ip nat inside source static 10.5.1.x 172.16.1.250 what about Nating outside into VLAN1 on 172.16.1.250? Would this still work?

Hi Reza, Thanks for that. I had actually come across that document and it was really helpful. Appreciate your adive on VLAN1 - its a old network config that I have picked up and we are beginning to slowly migrate out of VLAN1...a bit of a slow process but getting there! After doing some more research, I think STATIC NAT is the way to go..just a bit unsure. Below is the parts of my config that are maybe relevant. interface Vlan205 description Infrastructure_Subnet ip address 10.1.5.254 255.255.255.0 ip helper-address 10.0.3.100 ip nat inside interface Vlan1 description Legacy_VLAN ip nat outside access-list 1 permit 10.1.5.0 0.0.0.255 ip nat pool ucasinfpool 172.16.1.250 172.16.1.250 prefix 24 ip nat inside source list 1 pool ucasinfpool overload

I have a 6509 switch with Multiple Vlans. VLAN205 (10.1.5.*) is assigned to the Infrastruicture team. However due to some older applications in our organisation in VLAN 1, in their code are a range of ip addresses as a security measure. These are 172.16.1.* I have set up NAT from Vlan 205 (ip nat inside) to VLAN 1 (ip nat outside) to use 172.16.1.250 But, since this, members of the Infrastructure team can no longer ping their ip address or use Remote Desktop to the 10.1.5.* range. How can I fix this while still having NAT in place? Any help would be greatly appreciated.

I I have a Cisco WLC 4402 plugged into a Cisco Switch 3750 with 10 Access Points connected to this switch. I have a Juniper Netscreen 5XT Firewall, that I wish to place on this wireless network. Does anyone have any experience with setting up a Juniper FW and Cisco WLC? First Question would be were would I place the firewall?

Hi Mark, Thanks for your response. I have just been on the CCNA course, so trying to remember all the commands. The command: ip nat pool mypool 194.x.x.x 194.x.x.x prefix 30 Would that be the ip address of the External Router?

That could be the problem. there is no device handling any NAT translations. Any suggestions on what I could use and where in the link it would fit?

There are no ACL issues - its a basic router config. But I can ping the 10.0.0.101 address which has been assigned to my laptop over the wrieless network. Would it help if I sent you an amended copy of my router config?

Hi dennischolmes, Thanks for your reply, i have tried to create an interface on the controller as you suggested. however I get the following error " Error in setting VLAN and port. Cannot have multiple untagged dynamic interface on the same port" was ondering if you could shed any light on that error. Trying to setup the Trunk port on the 2950 switch, it won't allow me to set the encapsulation dot1q - is this down to the software version of the switch?
