I have 2 switches for my network.
1) Cisco Catalyst 500 series manageable switch
2) DLINK 1024D unmanaged switch.
Both are connected by RJ45 straight cable.
My broadband is connected to a port in the Dlink switch and in the catalyst switch I connected a modem for a leased line that connects my other remote sites.
The problem is:
The users connected to the Dlink switch does not get access to the broadband when they have the router's IP as the first default gateway and the broadband IP as the second gateway.
The broadband connectivity is through if I interchange the position, but then the remote sites are unreachable.
Is it because the two switches are incompatible? or am I doing some mistake?
Please help me out.
I think you need to go from the leased line to the ROUTER first. The switch you said was unmanaged...so as far as I can tell there is NO IP for the DLINK. If that's the case your router needs to be before the switch and after the modem.

DLINK is just a switch, not a router. The broadband is connected to it.
The leased line is connected to the Cisco Switch.
Communication is possible since the users from the DLINK switch can get updates from the Antivirus server which is connected in the Cisco switch. Ping between users is also through.
Keeping Router IP as gateway:: The problem is the router is for connecting only the remote locations, and is not for broadband. If i give the IP of router only as Gateway then the Broadband is not available.
Do you suppose that I should have the broadband through the router?
As of now, the ISP has provided a modem for the broadband which is connected to a port in the DLINK switch, this in turn is accessed by the users by putting in the Modem's IP as gateway along with the router's IP add.
This sounds like a routing problem to me. Users should only have one gateway. This should be the IP address of the router. This is handled either manually or through your DHCP. Can you communicate from a user on the dlink to a user on the cisco?
Does the Cisco switch have routing capabilities? And if it does are you running a sub-net with the other switch (now the DLINK you said is just a switch, right, not a router). If the DLINK is just a switch, and your leased line is connected to that first, you got a problem with routing.
