Hey,

We are migrating our network from a 192.100.100.0 subnet to a
192.168.1.0 subnet and I am having problems with our SCO 5.0.4 boxes.

One box is configured to run an end-of-day procedure and print reports
at 04:30. The printer doesn't start printing until 07:00 or later
sometimes. Under normal circumstances it would start printing at
04:34. This box has an IP address of 192.168.1.9 and the printer is
at 192.100.100.179. Here is it's routing table:

# netstat -rn
Routing tables
Destination Gateway Flags Refs Use Interface
default 192.168.1.251 UGS 5 227476 net1
127.0.0.1 127.0.0.1 UH 3 620393 lo0
192.168.1 192.168.1.9 UC 1 0 net1
192.168.1.9 127.0.0.1 UGHS 0 1630 lo0
224 192.168.1.9 UCS 0 0 net1

The router at the default gateway (192.168.1.251) is a Cisco 1721 set
up to pass all traffic between the two subnets.

The problem only seems to happen if the server hasn't been accessed by
a host on the other subnet (or tried to access a host on the other
subnet).

So far I have only noticed this happening with SCO boxes. My Windows
XP PC is on the new subnet and I don't have any problems connecting to
any hosts on either network (except SCO boxes).

Does anyone know what might be causing this or have any ideas on how
to fix it?
