You need do nothing on services. What firewall (and WHY) but if the firewall 
allows ESTABLISHED,RELATED back then it's not the issue.

I've seen the error and can't recall what the problem was ...

The port 34523 is a random number

[client] contacts server on servers-well-known-port
[server] says hi, lets talk on port mumblty7

Off they go

What your description says is:

CLIENT contacts server asks for kernel
CLIENT gets kernel (and initrd ??) but fails to mount the squashfs root file 
system.

Look at the /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default and check the 
kernel and initrd verses the etherboot versions

You are past the point of 'it does not work' firewall etc etc you are at the 
point of PXE mounts a kernel and initrd that does work, etherboot does not.

As a last resort get an etherboot image that does PXE
