The modem is a Netcom NB1300 it is connected via usb as I
have mentioned. The connection between the modem to the
telphone line is RJ111. The two computers connect via a
cross over cable (cat 5e).
I have tried ICS but it prevents either computer from
connecting. If I manually type in ip addresses the
computer connected to the modem has internet access,
however the web interface of the modem ceases. If I assign
ip automatically, the web interface works.
If I assign an ip, say 192.168.1.100 & put as the gateway
the modem ip, then there is no internet access. Delete the
gateway and internet access in restored. Giving 2nd
computer ip of say 192.168.1.101 only allows the twos
computers to talk.
In my nic list (via winipcfg) there is one for the modem.
This was getting its ip automatically too, the ips were
211.etc. I have released & renewed this and it is now on
the say subnet as the modem & has the modem as the
gateway. I thought this would help with the problem but
has appeared to have little effect.
The modem because its working via usb will automatically
switch on NAT, could this interfere?
One final thing if the ips are obtained automatically I
can ping both the modem and the ethernet simulation.
However specify the ip and I can ping the simulation but
not modem. Computer 2 cannot ping either modem or
simulation regardless of how it gets its ip. Computers can
always ping each other.
Hope this helps
