Rebuilding a OS/2 box that needs to have a static IP on my local lan.
Did this 5 years ago and didn't write down all the in's and out's now
that computer crashed - damn!

So, this is what I have - Cable modem / firewall / Lan

All other PC's work fine with static IP's on lan

This OS/2 box can ping the DGW on the FW and ISP fine but nothing shows
up on a web browser.

SETUP.CMD shows this

route -fh
arp -f
inconfig lo 127.0.0.1
ifconfig Lan0 192.168.1.35 netmask 255.255.255.0 mtu 1492

ipgate off

The route add net is not needed on a box that is inside on a LAN that
has a router connected to the ISP. You said firewall, so I am assuming
that the firewall is hosted on a router. It will be removed when you
fix the TCPIP configuration notebook below.

TCPIP Notebooks settings

Lan0
basic tab - IP 192.168.1.55 / 255.255.255.0
advanced 1 tab - broadcast "blank"
destination "blank" (when I place ISP address in here or DGW the os/2
box boots up with an error stating host is unreachable after NIC drivers
loaded)

MTU 1492

Hi Bill,
Pardon me for picky-backing on this post. I have long been puzzled by the MTU
1492.

My understanding is that that MTU is appropriate when using PPPoE. But, if the
PC is inside the router then the PC should be using an MTU of 1500 and the
translation takes place in the router which then talks PPPoE to the ISP???

All my PCs on the network use 1500 and I let the router sort out the DSL
interface to the ISP. Am I right?
