Hi Pete, Thanks for your reply - seems I've messed up at the first stage :( To answer your 3 points; Unfortunately on the superhub, there is no option to add a static route (if that's the correct term) for the 2nd subnet. I thought by having one interface on the Cisco 1841 router in the first subnet and one interface in the second subnet it would work. I thought that PC2 would use the Cisco router as it's default gateway rather than the superhub. I reserved the .126 address on the superhub's dhcp reservation pool, so that it won't be handed out elsewhere. I'd be really grateful if you could advise on a better set-up for this (one that will actually work). My main goal is to have a network that I can learn on and if I trash everything, won't affect the rest of the household. I have 3 Cisco switches that I could introduce, if this would help? Equipment that I have available; Virgin Superhub Test PCs, Laptops etc Cisco 1841 Router 2x Cisco 1801 Router 2x Cisco 2960 switch 1x Cisco 3560 switch Do I also need to buy a proper, advanced, wireless router and configure my superhub to just act as a modem? Thanks in advance, Gary.

Hi everyone, I've just started my CCENT course and so I'm trying to create a lab that is segregated from my home LAN, initially using a Virgin Superhub and a Cisco 1841 router. Please bear in mind that I'm a beginner at this, so it may not make sense or be completely illogical... The superhub for those that don't know, is a rebranded, restricted netgear VMDG480. It's essentially a cable modem and wireless router combined. The normal everyday LAN side of the network was setup by default to receive an IP via DHCP from the superhub in the 192.168.0.1 /24 range. Initially, I thought I could tidy things in preparation for my lab setup, by configuring the LAN subnet mask on the superhub to /16 and using 192.168.0.0 range for my 'everyday' network and 192.168.1.0 range for my 'home lab'. (Good idea or bad?...) Unfortunately, I'm unable to do that as the superhub only allows the last octet in the mask to be changed, so I changed the mask and it now reads 255.255.255.128, with the idea that I can still have 2 separate networks. From the picture above you can see the devices on the right hand side are all connected directly to the superhub and continue to work as normal. On the left side is where I've introduced a Cisco 1841 router and a laptop to test. The details of each device are; Virgin superhub LAN:192.168.0.1 DHCP scope: 192.168.0.2 - 192.168.0.126 Cisco 1841 Fast Ethernet 0/1: 192.168.0.126 255.255.255.128 Fast Ethernet 0/0: 192.168.0.129 255.255.255.128 PC2 (wired laptop connected to FE 0/0) IP: 192.168.0.200 255.255.255.128 Default Gateway: 192.168.0.126 (Cisco 1841's IP address) Would someone be so kind as to review this and tell me where I'm going wrong please? I thought about ripping out the superhub completely but I'm tied to it by my ISP :(
