Default Gateway of different network

[Sajeel Fahim]

I faced the following problem which I would like to share:

I have 2 DSL routers and my windows 2000 Professional host
connected to my HUB.

LAN IP of DSL router#1 is 192.168.0.1/24
LAN IP of DSL Router#2 is 10.0.0.2/24

On my windows 2000 Professional workstation, following is
the output of ipconfig /all
Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . :
Description . . . . . . . . . . . : 3Com 3C918
Integrated Fast Ethernet
Controller (3C905B-TX Compatible)
Physical Address. . . . . . . . . : 00-C0-4F-58-21-
55
DHCP Enabled. . . . . . . . . . . : No
IP Address. . . . . . . . . . . . : 192.168.0.59
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 10.0.0.2
DNS Servers . . . . . . . . . . . : 203.82.48.3
203.82.48.4
no secondary IP is bindid!!

I cannot do browsing but can see 10.0.0.2 in my arp table.

Now when i add a route 192.168.0.0 255.255.255.0 next hop
192.168.0.59 on my DSL router # 2 with LAN ip of 10.0.0.2,
i have full access to internet.

There's a big bug in windows 2000 as arp request of
different network are recorded in its table and defualt
gateway of different network is accessible through arp
brodcast and not through any routing device.

Windows 2000 team can u do sth to fix this!!

moreover if we try to add default route through command
prompt it does dot allow it to be different from the ip
network, the ip address assigned to the interface.

bye

This is a pretty confused post.

Your original configuration doesn't
function to reach the internet because
you've specified a default gateway
that isn't on the local network.

I can't follow what you're complaining
about as regards the arp table. Whether
or not an off-net IP shows up seems
irrelevant since you don't have a route to
reach it. (ARP, RARP and proxy ARP
take place below IP network routing).

If you want a secondary IP & network assigned
to the adapter, you can do that yourself. You
can not have a static and DHCP IP
or two DHCP-assigned IPs.
