Hi Guys
My old setup was a fairly simple one. I have the Netcomm NB5 ADSL2+ modem, which used to be connected into a TP-Link 8 port 10/100 switch. I also had a very old DLink wireless router which only supported Wireless B (11mbps) with WEP only. I used to disable the router fundtions of the DLink and connect it directly to the TP-Link switch - so that all PC's - wired and wireless had no issues accessing the net. All computers had static IPs managed by myself, except for a few handheld devices and a PS3.
Anyway - I have today purchased a Linksys WRT610N to replace both the TP-Link switch and the DLink wireless router. The CD setup failed to work (internal error 308 I think) - so I just launched the web-config page and went for good old manual setup.
For now, I've had to connect the modem/router (NB5) into one of the LAN ports of the WRT610N. This setup works as long as the clients have static IPs - since the WRT's DHCP is telling clients to use itself as the Def Gateway instead of the NB5. What I would prefer to do is plug the NB5 into the WRT's Internet (WAN) port, to free up a LAN port for other use. However, when I do this, while client PC's can PING the NB5 via the WRT, neither the WRT or clients can ping
www.google.com - address resolution (DNS) fails. The NB5's WAN IP is dynamic due to our ADSL provider's setup (iPrimus Australia)
Anyway - here's the IP Setup:
NB5 Modem/router: 192.168.1.1
WRT610N: 192.168.1.2
Static PC range: 192.168.1.20-29
Virtual PC range: 192.168.1.40-49
NB5 DHCP range: 192.168.1.2-9
WRT DHCP range: 192.168.1.70-79
So in order to access the Internet - I have to manually setup the IP so that I can tell the clients to use the gateway: 192.168.1.1. If I use DHCP - I'm given 192.168.1.2 and hence can't connect. The DLink had an option to specify what gateway to give to DHCP clients - I haven't seen this on the WRT yet.
I assume there should be some way to get all this working by plugging the NB5 into the WRT's Internet port instead. Here's what I've tried:
Change NB5 LAN IP address to put it on a separate network as you do with multiple routers:
IP - 192.168.0.1/24
Change WRT Internet IP to static - 192.168.0.2
Note that I've also tried setting the WRT Internet IP to auto - and the NB5 DHCP gives it the same x.x.0.2 address.
In both cases the WRT and client PCs can't access the Internet - despite both being able to ping and tracert the NB5.
I was never able to use the Internet port of the DLink router either - so I must be missing something as to how to get these devices to work together. It's been 12 months since my CCNA 1&2 course ended and I've hardly used the learned info since - so I'm just a little rusty - but have no problems understanding the lingo. I've had multiple routers working well together using enterprise devices, so I've found it a little frustrating not being able to get this working the way I'd like.
As always, thanks in advance
