Pfsense Virtual IPs howto?

Hi Guys
I have been trying to setup a Pfsense gateway, i have a couple of public IPs that i plan to do 1:1 Nat with some servers in my DMZ. I have gone through most threads about VIPs and 1:1 NAT, but i think am yet to get it right.

This is what i did

1. I created the vitual IPs using the Firewall->Virtual IP and ticked the "other" option.
2. I then created a 1:1 of the public IP to a Private IP in the DMZ
3. I then created a firewall rule on the WAN to allow TCP/UDP from ANY to the Address in the DMZ.
4. Also to make my VIPs pingable i created a rule on the WAN to allow ICMP destained for the VIP on the WAN from ANY

it still doesnt seem to be working, i cant even ping, could someone pls guide me through

Thanx lots

Call for Collaborators on VSAT monitoring using Free and Open Source Software

The ICT forum is interested in monitoring VSAT links of member institutes using free and open source software which will be non invasive and have no impact on the VSAT bandwidth. The information to be extracted from the data includes; the bandwidth utilization of the VSAT link, the various software applications in use and other relevant network traffic characterization such as the source and destination address, data volume, the protocol used etc.

Strategic Issues in ICT for Education

This is a summary of a blog entry at http://ibiztech.wordpress.com. The idea is a cursory look at some of the issues that face ICT development in educational sector in developing countries. Check the above address for details.

1. Web 2.0 may be disruptive …. but therein lies its potential. It is mass democratization in a traditionally power-imbalanced culture. I believe the collective IQ of students (although I prefer ‘learners’) amplified by passion for what they learn and brought together via Web 2.0 exceeds that of any single lecturer/professor/guru.

Asterisk Under Fire?

From my first contact with the open source IP PBX toolkit called Asterisk, I fell in love with it ... both as an IT expert and as a business-savvy person. Come on, what could be better than free (as in free lunch) as well as free as in free speech?

But of course, Asterisk - the pure one has never been for the faint of heart. U get to configure text files and keep track of several of them, not to talk of a somewhat cryptic commands. To be fair ... Trixbox (formerly Asterisk@Home) makes this a lot easier and of course there is a webmin module for Asterisk.

What do we need in a Network lab?

If the forum has the resources, it could establish a test lab in Abuja where we can try and these things and show prove of concept ... then member universities can copy. With such a lab ... any one of us could just pop in (or it could be more organized like a week for a team of 5 ppl to come to the lab) and work on a solution and get it to the level of proof of concept.

We need to develop Mukoms idea quoted above into a full fledged concept paper/proposal complete with a budget that can be presented to the Forum secretariat. Inputs from varied sources interested in these sort of experimenting are solicited so we have as extensive a plan as possible.

Discussions would necessarily revolve around the purpose of the lab in greater detail and how this will be effected. One thought that springs to mind as I write is the need to articulate any outcomes to the larger membership who are the ultimate benefactors of any evaluations/experimentation.

Linux-Windows Interoperability Steps UP

Hi all,
Just discovered something and its really making me excited. As you know for quite a long time now .... Linux has only been able to read but NOT write to NTFS partitions. For anyone doing a dualboot (Windows & Linux) computer, if you wanted to be able to share files on your hard drives between both OSes .. u had to keep a FAT32 partition around. Some guys have been working on the issue but it wasn't stable ... requiring a checkdisk on the NTFS partition everytime Linux used it .... UNTIL now.

They guys at http://www.ntfs-3g.org/ announced they finally got a stable solution. Check it out.

I just tried it out on my Ubuntu 7.04 and boy ... it works like charm. There's an excellent howtwo at http://www.ubuntugeek.com/widows-ntfs-partitions-readwrite-support-made-...

This is really significant for the following reasons.
1. Now you can consolidate your documents in one partition and access and modify them from both OSes.

Proposed FOSS Agenda - Anyone?

Hello all,
Was finally able to figure out the forum's interface today. I haven't seen any mail from anyone so I was afraid I could be missing all the fun.
I just thought we could maybe from the start identify some of the issues we want to discuss and brainstorm in this group. I am proposing the following:

1. Internetwork Routing with Vyatta & Openlinuxrouter and perhaps Zebra
2. Hotspot Management with Chillispot or Wifidog (I think NocatAuth is pretty much dead), FreeRadius and MySQL
3. Web caching with Squid
4. VOIP with Asterisk & Sip Express Router
5. Windows Desktop replacement/substitution with Ubuntu Desktop (or any other single CD distro --- Wazobia Linux maybe?)
6. Directory services (like Microsoft Active Directory) with Fedora Directory Services (FDS)
7. Network monitoring and security tools (Nmap, Wireshark, Nessus, MRTG, ngrep etc)
8. Gateway computer systems with IPCop

Anatomy of the Linux Kernel

As we have been talking about Linux based routers recently, some may be interested in this article which offers the history and architectural decomposition of the Linux kernel. The article is not in-depth but it provides a good overview of the Linux kernel architecture and its features and capabilities.
