If it's not a firewall/network configuration problem, the other 
possibility I could think of
would be the content for /tftpboot isn't labelled properly for SELinux, 
if you're using that.   From google, the
proper context appears to be "system_u:system_r:tftpd_t", doing a ls -lZ 
on pxelinux.0 should tell you if it
is labelled correctly.

By the way -- for searching the archives, this seems to work pretty well:

"your-keywords et-mgmt-tools site:www.redhat.com"
