RE: FreeBSD as a VPN Server/Router
If OpenVPN seems like a bit much to tackle you could establish the link with an easy protocol like PPTP (PPTP can be added to pppd with the port /usr/ports/net/poptop) and then IPSec traffic traversing the link. Some even argue that this is a good idea because it's two layers of encryption (not to suggest that the PPTP encryption methods are a particular challenge to break), but they'll be a performance penalty to pay as well.

I would suggest making the hardware at least current low end, or high end from a couple of years ago, to get the best performance. On side note, has anyone heard about the crypto lib for fast_ipsec and the Intel IPSec accelerated network cards (like the Pro 100/S)? I remember reading some time ago that there were, at the time, still issues getting the required info out of Intel to get the processor offloading working right. Is Intel still withholding the information? > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Christopher > Martin > Sent: Thursday, 10 August 2006 8:42 AM > To: FreeBSD Questions Mailing List (E-mail) > Subject: RE: FreeBSD as a VPN Server/Router > > > > > > > The FreeBSD Handbook has a chapter on this: > > > > http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/ipsec.html > > > > HTH. > > > > The only problem with IPSec is you need static IP addresses for the > tunnelling mode (unless somebody knows something I don't, at > which point I'd > really like to hear about it!). > > OpenVPN is about as good as it gets stability wise, and can > customised, > hacked, and altered in any way you need.

OpenVPN is about as good as it gets stability wise, and can customised, hacked, and altered in any way you need.

The challenge is to allow siteB to access these applications securely via the WAN setup. VPN comes straight to mind, but this is a new area to me. OpenVPN certainly fits your requirements. Besides a routed connection between two sides, it also offers a bridged setup, so it is ideally suited for connecting two Windows-centric networks. We use it at work for home VPNs as well as road warriors, configuration is straightforward, and performance is absolutely acceptable. IPSec has been mentioned before; I've had trouble understanding the configuration and how to diagnose problems. We did get it to work in the office, but only with a lot of trial and error. isakmpd and racoon are... idiosyncratic, to be polite. vtun has had major security issues in the past, so I would be wary, but I haven't looked into it for the past two years. pfSense is a FreeBSD-based firewall/routing OS, so you'd need to replace your existing FreeBSD routers with it, or add additional boxes.

Re: FreeBSD as a VPN Server/Router
there is a freebsd based project called pfsense (.org) that would suit your needs perfectly. ive been running it for quite a while now, and i think its the best thing since sliced bread. i have a IPSec WAN between 2 sites (my apt, and my servers that are at a colo). tons of features that are found on other expensive firewalls, are included! cheers, jonathan On Wednesday 09 August 2006 12:33, Odhiambo Washington wrote: > I am going to venture into the field of the security gurus so help me > God!
