This is not a support request related to openSUSE, but rather something I ran across earlier today that surprised me, that is technical related.
I purchased a Zyxel GS-105S V2 switch earlier this week, which is a very inexpensive 4 port Gigabyte switch. I already have a switch in our apartment that I use in my ‘study’ to connect 3 computers via one ethernet line to our router.
Our patio (outside) has one ethernet outlet and given both my wife and I like to sit outside at the same time, I picked up this inexpensive switch to use on the patio. Its small and lightweight and easy to take outside for use when we are both on the patio at the same time (using the web). We are using it for the first time today, and it works GREAT for both of us surfing at the same time via a wired connection.
What surprised me, is with this new Zyxel GS-105S V@ switch, some ports are blocked when in use with our router (a Fritzbox Fon WLAN 1&1 Home Server 50.000). My VPN ports are blocked, and also ports that I use with an office application are blocked. I can not even login to our router via this newt switch. Yet surfing works ok with this new switch. In comparison, I note with the other switch in my study (Level One GSW-0506) those same ports are not blocked, the VPN access works fine, the office application functions work ok, and I can login to the router.
After some investigation, I came to the initial (very tentative) conclusion that the problem is not this new switch per-se, but rather it is likely the Fritzbox router that is treating this switch differently.
I have not had the opportunity yet to check this out with our router (as it requires running in and out of the apartment to the server room) … but possibly sometime in the next few weeks I may check out our router - to see why it is treating this switch differently (assuming I have that assumption correctly).
This took me almost an hour to narrow down what I believe to be the likely culprit. … Of course my wife (in a teasing dig) said, it MUST be openSUSE Linux … to which we both had a laugh, as we knew it was almost certainly nothing to do with GNU/Linux, but we are aware that often GNU/Linux gets blamed for problems that are not understood.
Most interesting and never a dull moment in the oldcpu household.
