Hi Daniel, The route plugs into a modem.  Directly connect the client to the router, allows the client to access the internet. (Of course i had to tweak the config) Something weird but a bit of progress. On the PC.  since i'm manually entering the IP address, i've not enter the DNS But once i manually entered DNS enteries on my PC. I manage to connect to the internet, i could ping the internet/website , traceroute looks good --- At the later stage, my plan is to have a Server handles the DHCP and DNS, so by then i could set my ip to automatic assigned on my PC I'll do some more research, i think my concepts of some foundations on networking is shaky at the moment.
I've read through alot from the forums for the past weeks. I'm in need of some help/advice What i'm trying to achieve: 1. Have layer 3 switch - PowerConnect 6248 (192.168.5.2)-  handles all inter vlan-routing 2. Have Cisco Router 881 (192.168.5.1) - handles internet routing **At the moment, i can't ping from switch to router, neither i could ping from the pc connected to port 25  I'm currently using the following config: !Current Configuration:!System Description "PowerConnect 6248, 3.3.4.1, VxWorks 6.5"!System Software Version 3.3.4.1!Cut-through mode is configured as disabled!configurevlan databasevlan 5,10,40,50,60,70vlan routing 5 1vlan routing 10 2exitstackmember 1 2member 2 2exitip address 10.10.10.10 255.0.0.0ip default-gateway 10.10.10.1no ip domain-lookupip routingip route 0.0.0.0 0.0.0.0 192.168.5.1 interface vlan 5name "Connect to Cisco Router"routingip address 192.168.5.2 255.255.255.0exitinterface vlan 10name "Internal Staff"routingip address 192.168.10.1 255.255.255.0exit!interface ethernet 1/g13spanning-tree cost 200000switchport mode generalswitchport general allowed vlan add 5,10 taggedexit!interface ethernet 1/g25switchport access vlan 10exit  interface FastEthernet0 description LINK to SWITCH switchport access vlan 5 no ip address!interface Vlan5 description LINK to SWITCH ip address 192.168.5.1 255.255.255.248 no ip redirects no ip unreachables no ip proxy-arp!ip nat inside source list NAT interface FastEthernet4 overloadip route 0.0.0.0 0.0.0.0 [External Gateway ISP IP]ip route 192.168.10.0 255.255.255.0 192.168.5.2  Thank you in advance to all the network gurus...
