Wonder if anyone can help, I am currently setting up a network in Cisco Packet Tracer which consists of three subnets; 192.168.1.0/24 192.168.2.0/24 10.0.10.0/24   The devices on 192.168.* networks have no issue communicating with each other however the device I have on 10.0.10.10 cannot send or receive ICMP from either device on the 192.168.* address   One thing I did note is when I setup the switch that connects the device on 10.0.10.10 and ensured it was using VLAN 30 the switch told me that this is a new VLAN and set this up, maybe I have missed a step with getting the VLAN information on that second switch?         Configurations below   Router0 configuration   Router>en Router#sh run Building configuration...   Current configuration : 894 bytes ! version 12.4 no service timestamps log datetime msec no service timestamps debug datetime msec no service password-encryption ! hostname Router ! ! ! ! ! ! ! ! ip cef no ipv6 cef ! ! ! ! ! ! ! ! ! ! no ip domain-lookup ! ! spanning-tree mode pvst ! ! ! ! ! ! interface FastEthernet0/0 no ip address duplex auto speed auto ! interface FastEthernet0/0.10 encapsulation dot1Q 10 ip address 192.168.1.1 255.255.255.0 ! interface FastEthernet0/0.20 encapsulation dot1Q 20 ip address 192.168.2.1 255.255.255.0 ! interface FastEthernet0/0.30 description << Server VLAN >> encapsulation dot1Q 30 ip address 10.0.10.1 255.255.255.0 ! interface FastEthernet0/1 description <<Outside Interface>> no ip address duplex auto speed auto ! interface Vlan1 no ip address shutdown ! ip classless ! ip flow-export version 9 ! ! ! ! ! ! ! line con 0 ! line aux 0 ! line vty 0 4 login ! ! ! end ------------------------   Switch Configuration (Switch connected to both devices on 192.168.* CORESWI01#sh run Building configuration...   Current configuration : 1309 bytes ! version 12.2 no service timestamps log datetime msec no service timestamps debug datetime msec no service password-encryption ! hostname CORESWI01 ! ! ! ! ! spanning-tree mode pvst spanning-tree extend system-id ! interface FastEthernet0/1 switchport access vlan 10 switchport mode access ! interface FastEthernet0/2 switchport access vlan 20 switchport mode access ! interface FastEthernet0/3 ! interface FastEthernet0/4 ! interface FastEthernet0/5 ! interface FastEthernet0/6 ! interface FastEthernet0/7 ! interface FastEthernet0/8 ! interface FastEthernet0/9 ! interface FastEthernet0/10 ! interface FastEthernet0/11 ! interface FastEthernet0/12 ! interface FastEthernet0/13 ! interface FastEthernet0/14 ! interface FastEthernet0/15 ! interface FastEthernet0/16 ! interface FastEthernet0/17 ! interface FastEthernet0/18 ! interface FastEthernet0/19 ! interface FastEthernet0/20 ! interface FastEthernet0/21 ! interface FastEthernet0/22 ! interface FastEthernet0/23 description <<Uplink to Server Switch >> switchport mode trunk ! interface FastEthernet0/24 description <<Uplink to Core Router >> switchport mode trunk ! interface GigabitEthernet0/1 ! interface GigabitEthernet0/2 ! interface Vlan1 no ip address shutdown ! ! ! ! line con 0 ! line vty 0 4 login line vty 5 15 login ! ! ! end ------------------------------   Switch Connected to device on 10.0.10.10    SRVSWITCH01#sh run Building configuration...   Current configuration : 1196 bytes ! version 12.2 no service timestamps log datetime msec no service timestamps debug datetime msec no service password-encryption ! hostname SRVSWITCH01 ! ! ! ! ! spanning-tree mode pvst spanning-tree extend system-id ! interface FastEthernet0/1 description << Connected Device: 10.0.10.10 >> switchport access vlan 30 ! interface FastEthernet0/2 ! interface FastEthernet0/3 ! interface FastEthernet0/4 ! interface FastEthernet0/5 ! interface FastEthernet0/6 ! interface FastEthernet0/7 ! interface FastEthernet0/8 ! interface FastEthernet0/9 ! interface FastEthernet0/10 ! interface FastEthernet0/11 ! interface FastEthernet0/12 ! interface FastEthernet0/13 ! interface FastEthernet0/14 ! interface FastEthernet0/15 ! interface FastEthernet0/16 ! interface FastEthernet0/17 ! interface FastEthernet0/18 ! interface FastEthernet0/19 ! interface FastEthernet0/20 ! interface FastEthernet0/21 ! interface FastEthernet0/22 ! interface FastEthernet0/23 ! interface FastEthernet0/24 description <<Uplink to Core Switch >> ! interface GigabitEthernet0/1 ! interface GigabitEthernet0/2 ! interface Vlan1 no ip address shutdown ! ! ! ! line con 0 ! line vty 0 4 login line vty 5 15 login ! ! ! end     Obviously I have missed something some where, your assistance would be helpful.                         ...

Hi All, Currently messing around in my lab and I am trying to configure my 2821 so that I can use it connected to the internet. I have put my Virgin Media router into modem only mode and the 2821 tells me It has picked up a public address from the modem, I am able to ping 8.8.8.8 from the 2821 however any devices connected to this are not able to utilise the internet - any ideas?   Setup Virgin Media Modem - Cisco 2821 - Cisco Router - Endpoint   I suspect my issue is a simple NAT configuration error I have made but I am hoping you can help, configuration below   Building configuration...

Hi All, Hoping you can help. I have recently replaced a terrible ISP router with a Cisco 1841 router which seems configured correctly however ever since connecting this up I am having very weird internet issues..    For example when trying to browse a webpage it will give me "page cannot be displayed" however if I try a few times it loads but not correctly - However if i get the website to load correctly after a good few times it then seems to load OK (As if it is cached) but as soon as I go on a webpage I have not used it either slow or "page cannot be displayed"   I tried plugging my technicolour router back in and I get normal internet again. Please see below the config and advise me if anything is incorrect. The internet is that intermittent I have had to plug the Technicolour back in until I get a resolve.   I have DNS / DHCP running on a Domain controller - The router is simply the default gateway & the device my ADSL plugs into.   CCAuthorized access only!  Disconnect IMMEDIATELY if you are not an authorized user!

Hi.   Can anyone tell me what the hardware requirements are to run a Cisco Content Server virtualised?   Looking at the below link on table 5 I see that is it availiable as a Virtulized Application but lookinh further online I see nothing that gives hardware specifications required.   http://www.cisco.com/c/en/us/products/collateral/conferencing/telepresence-content-server/data_sheet_c78-626482.html?cachemode=refresh   Any advice would be great. ...
