Fritz!Box as DMZ behind an Experiabox version 10A

Posted by jpluimers on 2021/06/17

First of all: incoming Fritz!Box VPN behind an Experiabox version 10A fails, because the DMZ implementation of the Experiabox is faulty.

This worked just fine with the Fritz!Box as DMZ host behind a Ziggo Connectbox ([WayBack] Connectbox | Klantenservice | Ziggo).

First a few things to get regular TCP stuff to work: having your Fritz!Box as the DMZ host of an Experiabox.

I had a hart time figuring out some of them, so further below are also quite a few links just in case you bump into simular things.

  1. On the back of the Experiabox version 10A you find the SSDI and WiFi password on what appears to be a sticker, but is in fact a small piece of cardboard paper.

  2. Behind that cardboard paper is a sticker with the initial administrator password: shove out the piece of cardboard to reveal the sticker.
  3. After login (you cannot change the username, which is ADMIN or KPN) you have to choose a new password, which has these undocumented restrictions:
    • It cannot be the old password
    • The password must contain at least 1 special character (!@#$%^&*()_+|~- =\`{}[]:";'<>?,./).
    • The password must contain at least 1 number character.
    • The password must contain at least 1 uppercase letter.
    • Other restrictions I have not bumped into
  4. The default address of the Experiabox V10a is 192.168.2.254. Do NEVER change it, as KPN totally does not support that scenario and will force you to reset it before starting to help you out with anything. Logon as Administrator to the Experiabox at 192.168.2.254.
  5. Setting fixed DHCP leases was hard to find (I was looking for fixed DHCP, not DHCP reservation): Network -> LAN -> LAN DHCP (dropdown next to LAN) -> DHCP Reservation (up to 10 computers).

  6. The DMZ setting was not where I expected it: Network -> Firewall -> DMZ (dropdown next to Firewall)
