Those numbers have worked since around 2000

Yes, and that's probably why it does not work now. I assume you're using a mask of 255.255.255.0, and all IPs are in the same segment 192.168.1.x, so there's no way for the PC to know which NIC to use, routing wise.
Two NICs in the PC mean two segments which must be differentiated by their network address. Use
192.168.1.101 Amiga
192.168.1.102 PC (Amiga connection)
192.168.2.102 PC (DSL side)
with a mask of 255.255.255.0 (/24) or don't bind an IP to the DSL NIC at all.
Or enlarge the network mask to 255.255.255.240 and use
192.168.1.17 / 192.168.1.18 Amiga - PC
192.168.1.1 / 192.168.1.2 DSL - PC
Binary ANDing the host IPs with the network mask gives you the network address and these MUST be different for the two networks your running, otherwise your routing will be screwed up. Be aware that the host part of the IP (the rest) must not be all 0s or all 1s. Eg. a host IP of 192.168.1.16 with a 255.255.255.240 mask (/28) is not valid since 16 and 240 equals 16 and the rest is 0.

PS: Noone forces you to be a Verizon customer...  ;-)

Thank you! :banana:  :love:  :thanks:

Woohoo!!!!!!!  The ping works now!!!!!!!

But the LAN is still not quite working again  :-?

When I select "View workgroup computers" in windoze XP it sits there for a while then gives an error that it can't access that info, maybe I don't have permission, blah blah.

So I still can't actually share files between the 2 machines like I used to.

 YES they both have the same workgroup name I am 100% sure of this.


What should I do?



p.s. About Verizon:
1. Nobody told me about their user hostile policies before I signed up.  I just assumed it would be the same as SBC DSL.

2. Verizon is forcing me because they tricked me into a 1 year contract before I had any idea how crap they were.

3. In fairness, my upload connection speed is good.

OK I reset the Windows XP Machine.  It helped a tiny bit.

Now when I do "View Workgroup Computers" it gives no errors.
But it only lists itself, not my luvly A1200!  GRRR.  :madashell:
My LAN worked perfectly before, why has everything gone all wonky? :-?

Ok I got the last probs sorted out.

The final prob was this:

A few weeks ago when I moved I had to get new DSL service.
Unfortunately I chose Verizon.
As soon as I connected to the DSL I immediately and constantly was attacked by various Verizon servers.  All attacks appear to have come from different Verizon servers across the country.  They mostly tried to connect to Microsoft File and Printer sharing.  Always on a different port number.  Sometimes they would try multiple ports in a row.  Sometimes they would try to connect to some other service.  After a while they began trying to connect to "Kerio Personal Firewall  4 GUI" WTF?!?!

So anyway I blocked all this crap with the Kerio firewall.

I sort of overblocked it and caused my LAN file sharing to not work.

After fiddling around in the firewall settings for 15 mins I finally got it all sorted out.

Everything works perfectly now!

Thanks to everyone for your help!!!! :love:

Nice to hear that it's working again. :-)

I usually ignore the crapy workgroup stuff and just UNC access the machine \\computer\share and that's it. Even with two domain controllers, network neighborhood is not working 100% reliably - windows networking sucks!  :lol:

Actually you don't need much of a firewall on the Amiga side, since there's little probability that Amy attacks your XP box. :-P Just watch out for the DSL side; connecting 2k/XP w/o firewall is right next to suicide...
