I have went thru the knowledge base and have not been able to resolve my
issue. Here is my configuration running netware5.1.

I have a server functioning as a DHCP server. It has 2 NIC installed.
One is bound to 205.237.72.5 and one is bound to 203.237.72.5. My IP
ranges in DHCP are set 10 to 30 (i.e. 205.237.72.10 to 205.237.72.30) on
both segments.

Computers on segment 205.237.72.** can ping all computers on segement
203.237.72.**.

The reverse is not true.

Specific example:

205.237.72.17 can ping 203.237.72.10 but 203.237.72.10 cannot ping
205.237.72.17.
203.237.72.10 can ping 205.237.72.10 to 15.

Any idea what could be causing this?

I have installed a cable gateway modem at address 205.237.72.30. It does
not appear to have any router functions. I am able to access the
internet via the modem by all computers on segemnt 205.237.72.**. I need
to access the cable modem via computer on segment 203.237.72.**.

Can this be done?
