Weird LAN behaviour

[Ronky]

Hi...

I run a LAN the following way:

ADSL --> PC --> Amiga

One day, Amiga just couldnt get internet acces, as if there where no DNS, I tried to reconfigure the settings and everythinmg seems normal it just stoped.

I can ping machines bothways, I can even acces Amiga drives from pc and viceversa, can copy files both ways too, just internet acces is missing.

Anybody knows if theres a trojan in the Amiga/PC side causing this? or is this fault of one of those Winbug$ updates??? I run Amiga OS 3.9 and Winbug$ XP SP1

TIA

Is the network gateway address on the Amiga set to the PC's IP?

Yes...

As I said before, it had been working for several months, until last friday when it suddenly STOPED...

Thanx

How is the Amiga connected to the PC?

Can't you get an Amiga network card and then use a hub?

[Floid]

Have a friend drag a laptop or some other 'known good' system over.  (If it's Windows, make sure it's virus scanned first!)  See if it can get out.

If it can't, it's time to figure out what broke with the NAT program you probably had running on the PC.

Hi...

I have an A4066 ethernet card inside the A4000 and a crossed ethernet cable connected to both machines.

I use Samba for file sharing and Miami DX

Which computer is the NAT, the Amiga or the PC?

I dunno wot NAT stands for, but the ADSL modem is connected to the PC (using ethernet) and the Amiga is connected to the PC through a 2nd NIC

Maybe an update was applied to the PC (either manually or via automatic means) that patched or changed more than it should have???

I know this sounds obvious, but this sounds like the firewall on the PC or a corruption within ICS. Nothing is impossible... :-)

when you say, can't access the net, and you mentioned the DNS: can you browse to a site via IP address? Can you ping anything via IP address?

Right-click->manage on "my computer", go to event viewer, check system/application logs, perhaps there is something useful there.

You could also run a network analyser like ethereal on the windows machine and see what the Amiga is trying to do (and how the XP box is responding).

Try removing ICS and redoing it.

I agree, when I last used ICS it did manage to mess up all on its own a few times.  As csirac_ says try removing ICS compleetly and then reinstalling it and following the wizard again.

Are your machines set up static? Perhaps your provider has moved their DNS. While the PC might hear about this, the Amiga wouldn't. Make sure that you DNS is the same on the Amiga as it is on the PC.

Uh... ICS. It's as if MS make it hard to use it with non-Windows machines. I've heard of too many problems with ICS. Best use proper IP-NAT or SOCKS on your gateway such as MiamiDX, or a linux or hardware router.
