It is possible to configure your router via a web browser. Although it’s disabled by default, your router has its own mini HTTP server built in. This provides another way to gain access to the router for the purpose of issuing commands. To enable the HTTP server, you have to use the command "ip http server" from the global configuration mode.
cisco(config)#ip http server
Then open a web browser and point it to one of your router’s IP addresses. The interface is not really nice, but you can issue commands using hyperlinks.
For security reasons I still suggest that you keep the HTTP server turned off, since it offers just another point of access for potential hacking.
What is so bad about the command line? Configuring port forwarding is actually pretty easy, once you know the commands.
Type show ip interface to find the name of the interface you want to set port forwarding for.
The show ip nat translations command shows you the current port forwards on Router.
Type configure to enter the configuration mode
The command for port forwarding is: ip nat inside source static (TCPorUDP) (YourComputersIP) (PortToForward) interface (name)(PortToForward)
in you case:
ip nat inside source static tcp 192.168.0.1 5900 interface (name) 5900
ip nat inside source static tcp 192.168.0.2 5901 interface (name) 5901
replace (name) with the interface name you got from the first command.
Then press CTRL-Z to end the Configure Session
Type copy run start once you tested your settings and press ENTER for the question Destination filename [startup-config]?
I have heard of some commercial tools that let you configure your router via web interface, but they are very expensive (around 1400$).
You can try it out for 14 days. Go here.
If you want to play with a free one, go to Cisco (link) and check it out. (You have to be a member though.)
If you have any more questions, just come back here and leave a comment - I'm happy to help.

Going through the GUI would take too long, so use CLI to add the commands below. After that, check the GUI and see how those changes appear.
On all equipment use 802.1q tagging. The example below puts adsl ports 1 to 10 in vlan10 and ports 11-12 in vlan2. These vlans are 802.1q tagged on the ethernet ports.
switch vlan set 1 1~12:X enet1~enet2:FT DEFAULT
switch vlan set 2 1~10:X 11~12:FU enet1~enet2:FT VLAN2
switch vlan set 10 1~10:FU 11~12:X enet1~enet2:FT VLAN10
switch vlan set 17 1~12:X enet1~enet2:FT VLAN17
switch vlan pvid 1~10 10
switch vlan pvid 11~12 2
switch vlan pvid enet1~enet2 1
switch vlan priority * 0
switch vlan gvrp * disable
switch vlan frametype * all
switch vlan cpu set 1
Each port requires one or more VPI/VCI circuit. You could map different circuits to corresponding vlans. The config below creates a primary circuit 1/35 on each port. On ports 5 and 9 is another circuit 1/32 mapped to vlan10
adsl pvc set * 1 35 super DEFVAL
adsl pvc set 5,9 1 32 10 0 DEFVAL
Remember a dslam is just a switch, bridging packets from a VC onto a VLAN or straight onto ethernet.

You most likely don't have the correct IOS on your 3640 router. Other possibilities include bad VIC card or non-compatible VIC card.
