AW: [leaf-user] Bering NAT Traversal stuff

2003-03-21 Thread Alex Rhomberg
Craig,

 Thank you Alex for your input! Do I need to do a kernel recompile
 and stuff
 like that (it seems like I do), or do I simply download your
 kernel, the new
 IPSec.lrp package, necessary modules...and then substitute those
 in place on
 my current working Bering CD? Thank you!

You should be able to use the kernel, modules and ipsec.lrp on my page
without a recompile. Don't forget to replace all modules in
/boot/lib/modules (initrd.lrp) and /lib/modules (modules.lrp). The LEAF
construction kit on my page would do that for you :-)

If you want to compile your own kernel, you might find my description useful

Cheers
Alex

AW: [leaf-user] Bering NAT Traversal stuff

2003-03-20 Thread Alex Rhomberg
 Alex - One final question: Is there a .lrp package for the Super
 FreeS/WAN,
 or is it compiled within the kernel on your site? Is all I need to do what
 you mention, You should be able to use the kernel, modules and
 ipsec.lrp on
 my page without a recompile. Don't forget to replace all modules in
 /boot/lib/modules (initrd.lrp) and /lib/modules (modules.lrp).???

For Super-FreeS/WAN, you need the kernel, the ipsec.lrp package and the
modules, but not more.
I might eventually rename the package and call it sfsipsec.lrp or something
like that (I hate 8.3 filenames)

AW: [leaf-user] Bering NAT Traversal stuff

2003-03-19 Thread Alex Rhomberg

 1.) Do I understand it correctly that the latest Bering(s)(Bering-uClibc 
 Bering) both support NAT traversal? I'm a little confused because of the
 earlier post entitled Bering 1.1 and NAT-Traversal that referred to Alex
 Rhomberg's LEAF Page at
 http://leaf-project.org/mod.php?mod=userpagemenu=1402page_id=49
 seemed to
 suggest you might need to do something different if you wanted your Bering
 box to support traversal.

Bering 1.1 should support NAT traversal, but there still seem to be some
problems. I use my own kernel available on the page you referenced, and I
have tested it successfully with NAT traversal, plus it includes some more
stuff (ipsec algorithm patches and some netfilter things)

 2.) Is it difficult (or even possible) to connect to a box behind Bering
 using IPSec? (I have a Windows 2000 Server on my LAN that I would like to
 securely connect to.) I see that Jacques says NAT-Traversal patch allows
 FreeS/WAN to be used behind any NAT device by encapsulating ESP
 in UDP.,

That's the point of IPSec, secure connections to boxes behind firewalls.
NAT Traversal is needed for this setup:
Server --- Bering  --- Internet  --- NAT-box  --- IPSec Client

If your IPSec Client uses a public IP address, you don't need nat traversal.
It doesn't matter if your Bering box does NAT for your server, as through
the tunnel, you will address the server by its private address without NAT
