I currently have this setup with FC4, kernel 2.6.17, l2tpd from fedora 
extras and ppp from fedora. I'ts ppp-2.4.2 but you won't need any of the 
ppp-2.4.3 resources for this setup. I don't know about FC5, but it should be 
the same.

Just rebuild you kernel with NAT-T patch and use KLIPS instead of NETKEY 
(some people have reported failures with NETKEY and kernels above 2.6.15). 
I've tested openswan-2.4.5 and 2.4.6. Both do the job well.

I didn't need to set my external interface MTU to 1492. What I did need was 
to set l2tpd MTU and MRU to 1360.
