Help needed: V-O-I-P from Pocket PC, and Linux IP networking

Mellyn nîn! I need your helps.

First of all, I have the following setup at home (underlined systems are wireless ones):

  • In downstairs home office

    • On 4-port KVM, front part of office:

      • Telperion - COMPAQ SR1010NX - Intel Celeron 2.8GHz, 256Mb RAM, 40Gb IDE HD, 10/100 NIC, Ubuntu Linux: Hoary Hedgehog (2004)

      • Laurelin - COMPAQ SR1010NX - Intel Celeron 2.8GHz, 768Mb RAM, 40Gb IDE HD, 10/100 NIC, WinXP Home: SP2 (2004)

      • Vingilot - IBM ThinkPad 600E - Intel Mobile Pentium II 366MHz, 288Mb RAM, 20Gb HD, 802.11b PC-MCIA wireless card (Cisco Aironet), Win2K: SP4 (1999)

      • Orome - Gateway E-4200 - Intel Pentium II 400MHz, 64Mb RAM, 8Gb HD, 10/100 NIC, Gentoo 2004.3 (2005, new in 1999)


    • Yavanna - Apple PowerMac G4 - PowerPC G4 350MHz, 256Mb RAM, 10Gb HD, 10/100 NIC, MacOS 9 (2000)

    • Este - Apple "Yosemite" iMac - PowerPC G3 333MHz, 160Mb RAM, 6Gb HD, 10/100 NIC, MacOS 8.6 (1999)

    • Anduril - Gateway P5-75 - Intel Pentium 75MHz, 32Mb RAM, 500Mb HD, dual 10/100 NICs, NetBSD 1.6 (2001, new in 1995)


  • At home and in the office

    • Hirilonde - Dell Inspiron 6000 - Intel Pentium 4 1.6GHz, 1Gb RAM, 40Gb HD, 10/100 built-in Ethernet and 802.11b/g, WinXP Home: SP2 (2005)

    • Numerramar - IBM ThinkPad A31p - Intel Pentium 4 1.7GHz, 512Mb RAM, 60Gb HD, 10/100 built-in Ethernet and 802.11b, Win2K: SP4 (2002)

    • Turuphanto - COMPAQ Armada 7350MT - Intel Pentium 120Mhz, 48Mb RAM, 2Gb HD, 802.11b PC-MCIA wireless card (SanDisk CompactFlash), Win2K (2002, new in 1996)

    • Tulkas - Dell Dimension XPS D300 - Intel Pentium II 300MHz, 256Mb RAM, 40Gb HD, 802.11b PC-MCIA wireless card (Buffalo AirStation & PCI/PC-MCIA adapter), WinXP Pro: SP2 (1998)



On telperion, orome, and anduril, I would like to run some services:

  • IMAP, SMTP

  • PHP, MySQL

  • PHPnuke, TikiWiki

  • a web server with JSP (Tomcat, Blazix)



anduril is a NetBSD firewall using IPNAT rules. My whole home network gets one DHCP address from my ISP, Cox Communications. From my cable modem, a Cat-5 cable runs into one of anduril's NICs, then out to an 8-port 10-base-T hub on the floor of my basement office. All the wired systems are plugged into the hub, and all the wireless ones run off a Buffalo AirStation 802.11b wireless access point that is also plugged into the hub. The hub is an old CentreCOM MR820T (new circa 1997), unmanaged, and not a switch or router.

Right now, anduril gives local DHCP addresses to all of my home systems. I registered with DynDNS.org several times this year using addresses such as telperion.dynalias.org. Right now, this goes to anduril only.

What I would like to be able to do is either:

1. SSH into telperion.dynalias.org and get an interactive prompt for tunnelling into telperion, orome or anduril itself, or
2. SSH into telperion.dynalias.org:SOMEPORT and have my IPNAT table or IP masquerading setup route the connection

People have referred to #2 as port forwarding, but I have no idea how to do it under NetBSD. taiji_jian just gave me some docs, which I am plowing through, but does anyone have a specific recommendation as to which of the above is preferable, and why?

On a related note, has anyone been able to get Skype to work with an iPAQ (say, using PocketPC 2002 and 802.11b)?

Thanks,
Banazir
