Hi there can someone tell me where I put this on a Belkin Router? "We strongly recommend blocking inbound port 25 on the firewall for all except our IP address ranges, which are:203.84.134.0/23 (203."

It's already blocked by default.  The Belkin probably only has simple block and allow without settings for specific IP blocks.  You'll have to open port 25 to the internal address of the device in question.
Depending on the model of Belkin it will say something like network servers or port settings or something like that.

You'll have to have a much more expensive router to do IP filtering.  The options you mentioned don't have anything to do with what you want.  DDWRT adds a lot of high end features to cheap routers if it will run on yours.  I don't know if it will add what you want though.  Check their site for your model and instructions.  http://www.dd-wrt.com/site/index

So in summary, I cant do it without firmwaring my router or buying a more expensive one?

Correct.
Not sure what you mean by through routing but remote access can be setup just like you allowed port 25.
If you want to use remote desktop open port 3389 to the PC with remote desktop enabled.  Assuming you have a dynamic external IP address:  To access from outside you will need to setup an account with no-ip or someother dynamic dns service and install the client on a pc on the network.  The router may have a dynamic dns feature but I've never seen one work reliably.  If you want to use remote desktop for more than one PC you will have to setup port forwarding in your router if it is capable and use different outside ports.  For example PC A is 192.168.1.4 you would setup port forwarding in your router from outside 3390 to inside 3389 on 192.168.1.4  From the outside you would use your.no-ip.address:3390 to access that box.
This is all assuming you don't have your own server on the inside to use as an RDP gateway or SBS to use Remote Web Workplace.
