Adventures with the Cisco SRP527 ADSL2+ Router

This is a review of the Cisco SRP527 ADSL2+ router as much as it is an overview of my experience
with it. For a long time I was a huge fan of the Netgear DG834 series routers - for around $100 you got a router capable of wireless, 5 VPN tunnels, reasonable (but not fantastic) firewall and very reliable. It's only been since Netgear cancelled this excellent series, pushing users to the higher end models for VPN and using other, non-VPN capable routers for home users, that I started casting further afield for a new, reasonably priced VPN capable ADSL2+ router. WiFi wasn't that important - TPlink do a reasonable wireless access point for around $60 that we've deployed very successfully and I don't mind the separation of devices. One of my colleagues heard me bitching about the Netgear changes and suggested I check out the Cisco SRP range of routers. Usually the only Cisco routers I've played with are 800 series ones, or 1900 series - routers that require care and patience to set up, plus command line skills that I don't really have - I'm a *nix dude after all.

He was using the SRP547, the higher model than the one I use now, at home and loved it - he was able to control his kids access to YouTube and Facebook, killing their WiFi so they'd sleep and allowing him full access to his bandwidth :-) More importantly, they are reasonably priced and capable of both WiFi and VPN support. We started to sell a few of these devices and recent events enabled me to pick one up for home. I need a VPN to the office for remote backups, maintenance and monitoring so it was an excellent choice.

The Cisco SRP527 is an unassuming looking beast. It's in the same chassis as the 547 (and the RVS4000 for that matter) and offers a wealth of configurability. First things first - it has a web based front end that is clear and easy to navigate around. There are a lot of options, but they are fairly intelligently divided up and you can follow your nose looking for things. I set up my ADSL credentials, configured my firewall - note that you have to set up the Port Forwards, then the Advanced Firewall to get things moving in the right directions. I made the error of assuming that since I'd set up the Advanced Firewall options I didn't need to do the Port Forwarding - you do. But you don't have to set up the Advanced Firewall if you're allowing any access to the port forwards.

The 527 has 4 10/100 ports, one of which can be used as a second WAN port. It has 802.11N wireless capabilities and 2 phone ports

Rightly placed under the Cisco Small Business SRP500 Series Services Ready Platforms on the Cisco support pages, these are terrific devices. Not only did I have it up and running, with the VPN connected successfully to the SRP547 at the office, but I picked up almost 1Mb in speed on my ADSL line. Not bad at all for 15 minutes work. Even setting up the SRP547 at the office, with *many* more port forwards and some quite complex routing only took about 45 minutes.

The thing that probably impresses me most about this device is the reporting. The status page gives you a breakdown of so many different things its amazing. I can see how much data the port forwards are doing - individually, I can see WiFi stats, ADSL stats, VPN traffic stats and so much more. For someone like me it's awesome - I can watch this while I'm testing various different pieces of hardware and things that I'm doing - useful if I'm trying to work out what's sucking the life from my internet connection.

Things to note - when upgrading the firmware make sure you pick the right one. I inadvertently used the SRP520 firmware instead of the SRP520U firmware. Luckily a restore from backup fixed everything. With a reasonable price tag and lots of stuff it can do - it's well worth checking out the Cisco SRP527. With a bit of extra coin go for the SRP547 and get gigabit network ports!

Windows 10 Enterprise Eval - gotchas

After an annoying turn of events where my Windows 10 Enterprise USB drive failed, attempts to install Win10 onto a computer failed miserably. I turned to the net and managed to get my hands on Microsoft's Windows 10 Enterprise Evaluation. I have an enterprise key so I thought - cool! Here's the opportunity to get it going and to then upgrade the license later. Full install, patched etc and all is swell. Except when I try to upgrade. I straight up tried changing the licence key only to get a variety of errors, most of which are pertaining to the activation system being unavailable. The I try this: but it doesn't work either. Next I'll try this: h ttp:// And if all else fails, in goes the bootable USB I've now created. If only I'd had this in the first instance I would not be writing t

Fixing a black screen after doing a Kali Linux update

Kali Linux is a rolling Linux distribution designed for security and penetration work. You can find details on it here: . We run this excellent product for a range of different security work and it's been great. I built the image in VMplayer, then shared it to the team and we've all been at it since. A recent update broke it though - black screen, no network and completely unresponsive. There are lots of posts about similar things - mostly to do with graphics adaptors, however, we found that executing the following at a root prompt fixed it. But how to get to the root prompt from a blank screen? Linux has a number of terminals available to the user - most of us use the graphical one to do our day to day, but you can access a command line prompt without much trouble. Simply hold CTRL-ALT and then F2 or F3 down at the same time and it drops you to a command line login. BOOM. Time to fix it up. For me, and for the other fellas in the team, all it too was to

Plone - the open source Content Management System - a review

One of my clients, a non-profit, has a lot of files on it's clients. They need a way to digitally store these files, securely and with availability for certain people. They also need these files to expire and be deleted after a given length of time - usually about 7 years. These were the parameters I was given to search for a Document Management System (DMS) or more commonly a Content Management System (CMS). There are quite a lot of them, but most are designed for front facing information delivery - that is, to write something, put it up for review, have it reviewed and then published. We do not want this data published ever - and some CMS's make that a bit tricky to manage. So at the end of the day, I looked into several CMS systems that looked like they could be useful. The first one to be reviewed was OpenKM ( ). It looked OK, was open source which is preferable and seemed to have solid security and publishing options. Backing up the database and upgradin
