Sounds like you've solved your own problem and are tackling the original issue from the wrong angle.

Firstly: Can you not keep the DSLAM on the 200.200.100.80 IP address? This would solve your issue.

What are your subnet boundaries on the 192.168 and 200.200 ranges? Are they standard class C /24s?

Also, it doesn't matter if the DSLAM and PC are on the same switch when they are on different subnets. Switches only provide layer 2 connectivity. To route IP packets between subnets you need the intervention of a layer 3 device such as a router.

If you need the different subnets to have access to each other you'll need to define VLANs on the switch for each subnet then you'll need to trunk the VLANs out to a router (Or it can all take place on a layer 3 switch) where inter VLAN communication can take place.
