Odd router problems

[aychamo_aycono]

Hey guys;

I'm experiencing a really weird problem with my router..

First, my setup: I'm living in the Caribbean so I have to use a goofy ISP. We have a PPPoE DSL connection to them. I then have a Linksys Broadband Firewall Router hooked up to the DSL box, then I have a Linksys Wireless Vonage Router hooked up to the Linksys Broadband Firewall Router.

I have to run this double router setup because there is something screwy with the ISP here when you use the Vonage router to connect to them. They told me the only workaround is this double router setup.

Ok, that's fine. I have the First router (the one which is inbetween the Vonage router and the DSL box) set to 192.168.2.0, and the 2nd router (Vonage) is set to 192.168.1.0 ..

My computer uses wireless, so it access the internet via the 2nd (Vonage Wireless) router.

When I have this setup, the internet "kind" of works. The Vonage works fine, it connects to the Vonage server and I have phone service. However, about half of the webpages I try to visit refuse to load. This includes my own page (www.aychamo.com), and tuaw.com, and I was unable to connect to iTunes music store. However other pages loaded perfectly fine (ie, Google, Gmail, these forums, etc)

I hooked my computer (Mac Powerbook OS X 10.4.5) directly to the DSL box and I can access every webpage perfectly fine. So it has to be some configuration in the Router.. But I can't for my life think of what setting would prevent certain webpages from being loaded, while others load fine.

Does anyone have an idea?

do you have to have two seperate subnets? why not just make the vonage on the same subnet as the normal router?

2 dhcp's = fun for the whole family.

Can I do that? What would I set it up as? The 2nd router has to get internet somehow. Can I just plug the "internet" ethernet cable into a normal network port on the 2nd router instead of using the uplink/"internet" port?

The problem most likely comes from your ISP. If it was a routing problem, you couldn't access any of them. Can you ping/traceroute the sites you can't access ?

I have a similar problem, thanks to Qwest.

They sent me a DSL modem when I 'upgraded' my service here at work, that has NAT and DHCP built into it. Behind that, I have a D-Link 4 port router, which I need to keep because the DSL modem only has one ethernet port (it's apparently sent out with the assumption that everyone uses wireless now).

If I turn off NAT/DHCP in the modem, I can't get an IP address to the router without paying Qwest an additional $15/month for a block of static routable IP addresses.

The problem is, I use Remote Desktop (yeah, yeah) to connect to our company's central server, and having two routers in the same "chain" is causing that connection to drop about every hour or so. This is long-term unacceptable.

If I turn off NAT/DHCP in the router, instead of the DSL modem, do you folks think this will improve? Or do I need to go out and buy a switch/hub (I'm loath to do this).

I suck at networking stuff, so this thread comes at a good time!

Ok, are you using DHCP on either of those two routers? Turn it off and manually assign everything see if that helps. Also I don't know about newer linksys stuff but mine thats aging a bit now only does Class C addresses and it appears your using Class B. Dunno if that may be the problem but try this.

Set the router connected to the DSL line to an internal IP of:

192.168.1.1 subnet 255.255.255.0

Set the Vonage router to an external IP of 192.168.1.2 subnet 255.255.255.0 gateway of 192.168.1.1 and an internal IP of 192.168.2.1 subnet 255.255.255.0

Set your laptop to 192.168.2.10 subnet 255.255.255.0 gateway of 192.168.2.1

You'll manually have to assign DNS servers to whatever your ISP has on each device but if you want an external one 4.2.2.2 is one.

If that doesn't work...are you using a telephone to connect to the vonage thing? (I haven't looked into Vonage really) would it be possible for you to connect the phone to the vonage and the laptop to the linksys?

Perhaps try setting everything up on one class C subnet 192.168.1.X Then connecting to the linksys for internet access (default gateway) but setting the vonage software to look for the vonage device specifically.

Holy shit, it's fucking Jaytee.

Hey man, thank you for that advice. I will give it a go!

I had a similar problem with a Westell Wirespeed modem and a netgear Wireless Router. I have Bellsouth DSL so I had to go into the modem configuration, by entering the Default Gateway IP into a browser, and change the connection type from PPPoE to "Bridged Ethernet". That fixed it for me.

Good luck
