Being Thick No Doubt - Routing Query
 

Just got BB ( yeah :) ) but because of this need to reconfig my home network...

Now have the situation where I can resolve under tracert an IP addy but can't ping or reach it or browse it except on my main server...

Gah!!

Old setup


5 PCs & 1 Server all on same lan segment talking via a Cisco 1603 Router to the Internet. Server (W2K) running DNS, WINS & DHCP. Clients would look to DNS from Server which in turn would either know or look up from my ISP. All worked fine...

All on 10.0.1.x


New Setup

ADSL Modem attached to a Sonicwall SoHo3 Firewall, which in turn is now attached to the Server which now has 2 NICs, 1 for External & 1 for the Internal network. All clients now "should" request from the Server (gateway) & the Server should send those requests out via the SW to deal with...

SW/Server on 192.168.x.x & Clients on 10.0.1.x still

Ideas?

Oh & this is something that I have set up before a number of times on other networks & works sweet as :rolleyes: Just not for me :rolleyes:

Are you running a firewall on the server and allowing ICMP packets through?

If you cant browse then it sounds like config is wrong..

What is doing the proxying / forwarding etc on the server...

David

The server internal nic & the clients go on 1 ip range & the server external nic & the adsl box goes on another ip range.

Example:
Server internal nic: 192.168.16.2 gw: 192.168.16.2
Clients: 192.168.16.x gw: 192.168.16.2

Server external nic: 192.168.1.10 gw: 192.168.1.1
ADSL modem: 192.168.1.1

This doesn't sound like what you've got....?

Also have you configured your server to use the 2nd nic for Internet access? Are you also using a firewall/proxy on the server?

Oh, make sure that DCHP isn't running on the firewall box.

Not running a FW on the server - was previously working with the Cisco

Doubtles config

Its a Windows 2000 Adv Server

Example:
Server internal nic: 10.0.1.1 gw: 10.0.1.1
Clients: 10.0.1.x gw: 10.0.1.1

Server external nic: 192.168.168.1 gw: 192.168.168.168
ADSL modem: 192.168.168.168

That's what I got...

How to tell server to use 2nd NIC for Internet as it already does that bit (typing this on server as can't get cleints t work!!)

post up a "route print" off the server and clients please

oh and what setup did you have before ? ISDN RAS on the server?

Just had 1 NIC talking to a Cisco 1603 (NAT'd ISDN) Router. That NIC also had internal stuff going through it too.

I've installed RAS now with the hope of the obvious

I might be asking a silly question here, but why do you want all your traffic to go through your server, and not just hang all your devices off the back of your SoHo?

erm 'cos thats the way I've always set 'em up & eventually I'll likely run some poxy software when sprog gets nearer the internet

As said above, it's always worked before, the only thing different this time is that its not a brand new install of server, changing from previous setup

what is the default gateway set to on the dhcp?

David

tracert and ping both use icmp as I'm sure you're aware. Do you mean, on the clients, you're getting dns resolution, but no traffic, or you are getting a complete tracert, but no pings/web etc?

Could you post up a tracert to www.google.com form your client and server if this isnt the case?

10.0.1.1 for the clients

jj - it resolves the domain, gets 1 hop to 10.0.1.1 (as expected) then times out for the next 29

Running DNS on the server & if that doesn't reconcile, it bogs off to demon DNS as spec'd in the SW or as the forwarder in DNS properties

No ping returns either

Have you turned on ip forwarding?

It was H

Youve got 2 default routes set (1 on each NIC) - remove the D/G from the inside NIC.

Not saying its the problem - but you only need 1 Defaukt Gateway...

It now works :D

Disabled RRAS & re-configured it & hey presto :confused:

Oh well - bloody routing I hate it :mad:

But thanks to everyone for their help :D

:cool:

Replace the user :p
