Of course.

If the enrcyption is any good (and the router in question is
not partcipating in the encryption) then it can't decrypt it.
Naturally, it can look at (and modify) any unencrypted
packets.

Routers that support the filter and capture RMON groups can
send copies of the packets elsewhere.
>If it is true, Do you know any router as this?
Any general-purpose OS acting as a router (and most can)
can easily monitor packets. This includes NT, Win9x, and
any unix.

There are add-on devices that can monitor packets as well.
These include WAN sniffers, and RMON probes.
It sounds like you're asking in general if you should be
worried about traffic monitoring across a network,
most likely the Internet. Yes, you probably should.
