Web admin access to home router

[Jones, Scott (GE Money, consultant)]

I am trying to get my mailman server set up, and have run into network
issues. I have a linksys wrt54g router, and have enabled web access. 

Here's my question: If I can access the router remotely, then I should
fairly easily get access to my server box established, is this correct? 

The other question: Is it even adviseable to allow web access or is that
asking for trouble? How hackable is a router, in the face of a
determined hacker?
