Any networking guru's out there?

[Anonymous]

Am having a few networking probs at home and I'm stumped:S
Think I may be over looking the obvious but cannot for the life of me get my head together today

Anyway my hardware:

1: NTL Cable Modem
2: Linksys DSL Router
3: Home built PC
4: D-Link Access Point
5: Sony Vaio Laptop

Firewall - Norton Internet Security, soon to be a Smoothwall Firewall once I have built the spare machine


On the laptop, Norton is configured to allow the PC's IP address and subnet through

On the PC, Norton is configured to allow the laptops IP address and subnet through

Both machines have Windows firewall turned off

Laptop can ping PC so there is the physical connection
PC can ping laptop so there is the physical connection
Both can ping AP and Router

Laptop cannot access 'view workgroup computers' from 'My network places' it just takes ages then comes back and says 'Mshome is not accessible. You night not have permissions to access this network resource blah blah blah the list of servers for this workgroup is not currently avaliable'

PC cannot access 'view workgroup computers' from 'My network places' it just takes ages then comes back and says 'Mshome is not accessible. You night not have permissions to access this network resource blah blah blah the list of servers for this workgroup is not currently avaliable'


Any ideas?

double check file and printer sharing is selected for a start.

disable / uninstall norton aswell to eliminate that.

 

[Hotshot]

disable norton
are PC's on the same subnet?
put each PC on the same workgroup if not already

try accessing the pc's from a windows explorer windows, or anything with an address bar, using \\ip.address.here or even \\computername

do an ipconfig /all on each pc and pop the info in here

 

[Anonymous]

Right I disabled Norton

The laptop can now see itself only in 'view workgroup computers' and not the PC
The PC can now see the laptop only in 'view workgroup computers' and not itself

Both machines are on the same workgroup

Using windows explorer didnt help either

I did an ipconfig /all and both are identical mate, only difference are the IP's, Physical address's and host name's

Almost there lol

Aaaaaha

The pc has just popped up in both Mshome windows, must of just needed time to refresh.


Must be this Norton piece of sh1t, roll on smoothwall lol

Windows networking is shite.
It uses messy ways to do workgroup stuff.. infact, I don't even use the workgroup thing now, heh.. ever. Or recommend it. Ever. Ever ever ever.

How would you recommend I set it up Daz?

 

[Daz]

I'd just access the machines by going to \\name\share or \\ip.add.re.ss\share

It'll just work without all the broadcast then

 

[Anonymous]

Oh and the laptop still cannot see the PC's shared files but the pc can see and access the laptops files:banghead:

It cannot find the pc doing \\name\share or via ip\share

 

[Daz]

Erm, \\ip\share should always work.. it works cross subnet's, so it's not even related to a work group.

If it doesn't, something else is blocking stuff is my guess?

 

[Hotshot]

File and print sharing enabled on both machines? Are the shares protected or open to all? If not, add the laptop as a trustee.

Daz is right \\ip\share should always work, and if not \share \\ip definitely should. Im a little worried about your AP on top of a router setup at this point, as it's starting to smell like a NAT issue.

Shouldn't even touch NAT, as AP should be on the LAN side of the router.. (If it is leaving the LAN, then.. er.. something is seriously broken with that router config )

 

[Daz]

What IP range you using on the LAN?

And subnet?

 

[Hotshot]

Seems to me that traffic is coming through that router, hitting the AP and not making its way to the Vaio? I've got a Linksys AP+Router combi sitting behind a Cisco DSL router at home, and it HATES having to deal with any wired connections sitting on the Cisco. So much in fact that i've given up accessing wired shares form the machine upstairs.

 

[Daz]

Heh.

I dunno,

I have a Cisco ADSL Modem -> WAN port on a Firewall box which then has a DMZ interface to a public server (with static NAT entries for public IPs) and a LAN interface to an access point/switch with my main PC connected to the switch.

My laptop (wireless) can access SMB shares on the server in the DMZ (different subnet) and access shares on the PC (wired). (With firewall rules set properly for LAN -> DMZ communication etc.. )

So, it should definetly work by just having a router -> AP

A router behind a Cisco Router (take it it's doing routing?) wouldn't work.. as the Linksys router would be using it's WAN port to the Cisco.. (at a guess)

Wired clients on the Cisco would be classes as "Public internet" machines to the Linksys Router.. and it'd block them.

 

[Hotshot]

ADSL -> CISCO -> Wired port -> Internet uplink on the Linksys.

As i say wifi-> wifi fine, wifi-> wired no no. I dont have the spare hardware to setup a linux box to get a nice cushy samba share setup going sadly as thatd be an ideal solution.........equipment needs to go missing from work.

 

[Daz]

yea, Wifi -> Wifi would stay inside the Linksys.

Wired -> Wifi would have to go via the WAN port on the Linksys I guess? Which wouldn't be allowed.
Wired on the Linksys Router to Linksys Wifi should work fine (and does whenever I've set it up with any other wireless router)

(If I'm reading it right.. heh)

 

[Hotshot]

aye wired to wifi on the linksys is fine but as you say the linksys locks it down with re: wired connections on the cisco.

back to the matter at hand ;D

 

[Daz]

back to the matter at hand ;D

Haha, yea, whatever his name is now has no network connection.

 

[Anonymous]

lol, have been away doing my chours, gotta keep her sweet.

Anyway, im using 192.168.x.x range and 255.255.255.0 subnet

Modem is connected to linksys via WAN port
PC is connected to port 1 on the linksys
AP is connected to port 2 on the linksys

Both AP and linksys have had the IP's added to the NAT list

What gets me is the internet always works on the laptop and that receiving it wirelessly via the AP so the NAT is allowing traffic to and fro

Oh and Daz, you make me wet with your geekiness...........keep going, but in a huskier voice

 

[Daz]

What's a "NAT" list? Heh.

PC's should have a default gateway of the Linksys. Linksys should simply have your live IP on the WAN port.. and a local IP for your LAN.

If anything coming into the Linksys is not local (e.g 192.168.0.x), it should NAT (normal NAT, no 1:1 stuff etc..) it out of the WAN interface. If it is local, then it should just send the packets out on the LAN side (the Linksys's LAN ports)

If you have some weird config, reset your Linksys and configure it again (bearing in mind if you need to set any MAC spoofing for NTL auth systems (dunno if that's still in operation!)).
