Cannot see past Router

[notarat]

My RPi can see all my networked devices, but cannot access the internet.

I have made no entry or configuration change to the Router other than to reserve the IP for the RPi, like I do for all other networked devices.

This has me stumped so I would appreciate some suggestions.

Network Configuration:

Motorola Surfboard Cable modem runs to D-Link DGL-4100 4 Port Router/Firewall

DHCP Enabled on Router
It serves 192.168.0.100 to 192.168.0.199
MAC Filtering is OFF (Verified 3 times)

DGL-4100 has runs to:
1 - NET Gear 8 Port 10/100/1000 Switch
2 - NET Gear 4 Port 10/100/1000 Switch
3 - D-Link DAP-1522 Wireless AP/Bridge
4 - Raspberry Pi (Wired)

DAP-1522 is used to connect my Wireless devices (DROID1, Asus TF-700, iPod Touch) so is not really relevant.

8 Port Switch connects to:
Samsung TV 192.168.0.121
Sony BluRay Player 192.168.0.133
File/Print Server 192.168.0.145
Security System 192.168.0.157
Home Theater PC 192.168.0.119
Backup Gaming PC 192.168.0.161
HP4100 Printer 192.168.0.133

4 Port Switch connects to:
Primary Gaming PC 192.168.0.102
Test Server 192.168.0.104
MEPIS Box 192.168.0.106

DAP - 1522 192.168.0.149 (All Wireless devices connect fine.)

The Raspberry Pi connects to my home network fine. I can browse the network, access remote files, move and copy files, etc.

The RPi can ping every machine listed, as well as both Routers.

Each machine listed can ping the RPi and both Routers can ping the RPi

The RPi cannot see past the DGL-4100. I cannot access any web site. I cannot ping anything past the Router.

If I remove the DGL-4100 and connect the RPi to the Cable Modem directly, it works like a champ

Is there some sort of compatibility issue between the D-Link and RPi? What am I missing here?

Can you ping an ip address in the outside world eg 8.8.8.8 ?

Power cycle the router and any switches between Pi and said router....

$ sudo vi /etc/resolv.conf
Modify or enter nameserver as follows:
nameserver 208.67.222.222
nameserver 208.67.220.220


vi or whichever editor you have but put 2 ip's for nameserver these are just examples

4.4.4.4 is googles dns in the US

have you configured the Gateway entry (to point to your Router) in the Pi networking?

I'll give it a shot when I get home this evening. I must admit I am a bit rusty at my linux commands...

I should have run an ifconfig and written down the information listed when I bypassed the router so that I could mod the conf file after reconnecting the router...I was just too loopy from lack of sleep...

Damn legos...

Thanks Mate! I will try that this evening and, if it works, I'll finally be able to move onto the next step...remaking my Lego case into something a little more spacious.

I just ordered 3,100 Legos today, lol.

Damn legos...

I'm back. And this time, I'm on my RPi box.

It would seem the one area I ignored as not being relevant (my wireless AP) was the cause of the issues.

I'm not sure how it got it, but when I did a tail of resolv.conf, it was pointing at my DAP-1522.

I must have tried one of my wireless dongles at some point and forgotten about it.

I made sure the resolve.conf file was correct and restarted my networking and it works just fine now.

Thanks to all who have provided assistance! I think I'll celebrate by watching a movie tonight while I plan on how to build my expanded lego case.

And just to make sure I have enough pieces, I ordered another 700, lol!

Damn Legos...I think my running total is about $350 now for a $35 computer...

Another $100,000 in legos and you can move in with it.
