Multi-WAN routers compared

Posted by jpluimers on 2016/05/20

Mikrotik have statistics and way more features. Of the not so good features on the TP-LINK ER-5120 multi-WAN router (none of which are mentioned in their documentation), the worst 2 are:

  • Virtual-Server table can only handle 32 incoming port redirects
  • no IPv6 support
  • both incoming WAN and outgoing NAT isn’t very stable (my guess it’s a NAT table filling up)

Buffalo WLAE-AG300N DHCP client is buggy and adds a NULL character to the host name.

Posted by jpluimers on 2016/05/13

Buffalo WLAE-AG300N is one of those buggy DHCP clients… Even running firmware Ver.1.85 (R1.05/B1.00)), it gets the length of the DHCP host name wrong so adds a bogus NULL byte to that name.

@Buffalo: please fix this.

The DHCP client options are of structure Type/Length/Value so a client is supposed to set the length of the hostname to exactly the number of characters.
However there exist buggy clients that either send a length of 1 more and a \00 at the end of the name, or send a fixed length and pad it with \00 as necessary.

It’s fanless, support SFP+ and many people seem to like it.

From the #alleskaputt -Dept: Hotel, Internet of Shit Switches, Predictable IP… boom!

From the #alleskaputt -Dept: Hotel, Internet of Shit Switches, Predictable IP Addresses (== Room Number) and no security. Right. – Kristian Köhntopp – Google+

referring to: mjg59 | I stayed in a hotel with Android lightswitches and it was just as bad as you’d imagine

And then I noticed something. My room number is 714. The IP address I was communicating with was 172.16.207.14. They wouldn’t, would they?

Then you get this:

Two opinions on Netflix and blocking: they hate Netflix or contact tr@netflix.com and try to solve …

Posted by jpluimers on 2016/03/28

Basically there are two opinions on Netflix and blocking:

  • TL;DR: People use VPNs for security, Netflix fucks them up, they hate Netflix for that and just torrent that shit.
  • tl;dr If you have issues with Netflix on public Wifi, contact the provider and forward tr@netflix.com to them so they can settle issues.

I’m not a netflix user (or user of any form of DRM) as I really dislike the fact that DRM means for any reason your license can be ended. I’ve seen too many players going out of business or taking decisions turning.

So I buy CDs, DVDs, BlueRays or DRM-free media files. Now it’s my problem of making proper back-ups to ensure future access to them (:

The DRM walls and ladders war^w game has gone so far that in this case, Netflix is blocking even though the WiFi provider / proxy / VPN is in the same country like the below imgur image:
