VERY basic help needed (SOHO 91)

[phoneguy2286]

I have a SOHO 91 that I wish to use for very very basic home use. I am not familiar with IOS at all, and this is my first attempt. I have successfully hosed the GUI interface, and have to do everything command line. I have been able to initiate DHCP, but still having a few problems.

I can't get the DNS to work properly, and it looks like every time I reload the router, the interfaces drop and don't come up. Does anyone have a very basic config, or can you look through my config and give me some pointers?

THANKS! If anyone needs PBX assistance, I can possibly return the favor.

Were you able to add the static route on the modem? If not then your LAN/PC will not have access to the internet.

 

[Jsteve]

If you have the P1600, then you must reset the xDSL line to activate the static route.

[phoneguy2286]

I will try that, but I thought that was the reason for having a router in the first place....

the modem talks to the router..the router ROUTES between LAN and WAN..

I did not have to set up anything like this in the dlink scenerio..

dlink is using LAN addresses of 192.168.0.100-150
and getting DHCP from the modem on the WAN interface of the router.

 

[phoneguy2286]

I do not see any static route settings in the modem.

 

[Jsteve]

What type of modem? if it can not do static or dynamic routing(rip) then your set up will not work.

The router knows how to route, but you problem is that your modem does not know how to route back.

each device has routing table that acks like a rode map. So if ping a Internet site from your router, the packet is sourced with a ip address of the interface 192.1682.4

the packet coming back from the modem looks at it's routing table and sees the the 192.18.2.x subnet is in it's routing table as a directly connected interface. there for the packet is successfull.

Now if you ping the same web site from the router, but source it from the 10.10.10.1 interface it would fail. The packet would mack it to the internet site and back all the way to your modem, when your modem looks at it's table for the 10.10.10.0 subnet it would not find it and then drop the packet.

 

[phoneguy2286]

the static route is not set in the modem..

it works with the dlink

I am kinda clear on the concept, just wondering why I did not have to set up that scenerio on the dlink..

it was pretty simple...tell the dlink to grab all info from the modem (dhcp), then tell the dlink to distribute ip addresses to the lan (dhcp)..

that was pretty much it. i never went into the modem.

I don't want to start goofing with configuration onthe dsl modem.. I think it is a 660. afraid I would hose it also...

once again, I never told the modem to go look for the lan addresses on the current scenerio...

I have also had this set up before, and never had to go into that much detail..

I had the cisco connected to the WAN (modem), and even hung the dlink wireless off the cisco...with no problem.

--I lost the previous configuration, and in trying to reinstall also screwed up the gui interface on the cisco..so was trying to re-build..

also, I cannot even ping the modem from the lan.

 

[Alterac]

is ip routing enabled?

run this:
ip routing

why are you trying to use the cisco anyways? it looks like your dsl modem has a built in router with dhcp and everything.

[phoneguy2286]

I was just trying to put in another layer of manageability..

I had the set up before to allow vpn access to my corporate network through the cisco, but kept all my home network segmented via the dlink...

I know it wasn't the cleanest scenerio, but that kept everything on the vpn network on the cisco, and physically separate from a total different network (home pc's printer..stuff like that)

 

[burtsbees]

IP routing is taking place, hence the route table. It now has a route to the 192.168.2.0/24. Try power cycling the modem now.

How exactly did you hose the web interface of the router? The only way I can think is that you erased part of flash...if this is the case, you may have to reload an IOS image to the router.

[phoneguy2286]

once again, thanks for your patience.

here's what I got...STILL no access past the router can't ping a web address, or the address of the modem..

I don't see a Zyxel 600 on their web site, is it a 660?

[Jsteve]

Also the Dlink is like a L2 switch. It pulls the DHCP IP from your modem, but the rest of the ports are Layer 2 that uses that IP address to communicate. Wiht the Router your adding another Layer3 hop, And the only way to get it to work is to configure static routes on both the router and modem, or configure a dynamic routing protocol

 

[phoneguy2286]

looks like a model eq-660r

which is easier?

like I said, I really don't remember doing this before..maybe it was done through the gui.

anyone have crws?

 

[phoneguy2286]

HOLY CRAP

I got it...

the CRWS was a damned java issue...

also....it looks like it configured it using a combination of all recomended procedures

Congrats!!

Duh, don't know why I didn't think of that. I hope you understand the concept. The modem does not know how to get back to the LAN subnet (10.10.10.x or 192.168.1.x), but it does know how to get back to the 192.168.2.x subnet. So you Natted you LAN to make it look like evrything is coming from 192,182.2.x:xxx
