scyld beowulf server problems

[Matthew Freeland]

Greetings, fellow linux enthusiasts!

I have recently constructed a new computer out of spare parts to act as my
personal home server, a computer running 24/7 hosting mfreeland.net on
telnet/http/ftp/email/dns/nfs/ntp/samba/dial-up.  I decided to use scyld
beowulf because it runs lightning fast on elderly hardware and has the
option of booting the other computers on my network as slave nodes for
supercomputing enjoyment.  The problem, however, is that none of the
servers running on the machine are accessable from the internet.  I am
using a service from mydomain.com to point mfreeland.net to my roadrunner
ip address. From there, it enters my linksys router which port forwards all
the necissary ports to the server's lan ip address.  I know this setup
works because if i plug the same ethernet cable from the server into my
laptop, mfreeland.net is routed to the servers running on my laptop.  In
order to fix the problem on the server, i have tried to open up the
firewall, but it already seems open: iptables shows input: accept, forward:
accept, and output: accept.  The one weird thing i have noticed is that if
i point my browser on the server to 192.168.1.1 (the lan ip of my router),
it loads the test apache page running on that server, which actually has
the ip address of 192.168.1.103.  Also important to note, from computers on
my lan, if i type in the server's local ip address, the apache page loads;
however, if i type in the wan address, i get nothing.  I have also tested
the connection with telnet and got exactly the same results, so i don't
think it has anything to do with apache.  Does anyone have any ideas as to
how to make the server accessable via the internet?

Thanks,
