Re: IPsec, VPN and FreeBSD

Thanks Julian:

Well, the another site is using a linux box for
firewall. We have extra PCs available so we could
build another FreeBSD box. That probably makes the VPN
setup a lot easier between two sites.

As to the roaming users, very unlikely there will be
dial-up line, but those users could be on road and
using ISPs to connect the internal lab. both sites are
labs.

I will try the roaming clients<--->freebsd vpn server
first.



ok google for mpd and pptp

Hi:

We intend to build IPSec based VPN server on


FreeBSD


platform so that we can access internal network of


a


lab. The remote side will use VPN client and could


be
from anywhere of the Internet, or may be from the


another site of the company. From the hnadbook, I


saw


the sample of site-to-site configurations and we do
have one FreeBSD firewall (running ipfw) on both


site


and another one on another site (both have


firewalls


on them), can we do that? Also what about the
client-server model? What kind of clients do we


need


in order to connect to the FreeBSD/IPsec/VPN? Any
tips/information for the configuration of the
clients/server model on internet?

Any help will be greatly appreciated.




there are almost too many options to mention..

however you should be able to implement pptp
tunnels (as used on windows) using mpd (in ports)
alternatively there is always ssh or ipsec.
(or a combination of them)

If as you suggest, both ends are freebsd, then I've
used mpd over ssh with great effect.
use the 'tcp transport' option of mpd and connect it
through an ssh tunnel.


is the 'client' roaming or at a fixed address? if a
fixed address then ipsec becomes easier.






Thanks
