Early on in my first career (i.e. childhood), I learnt about features. I would pore over the Argos catalogue with a biro - “got! got! want! want! got! - choosing the toys I was going to ask for at Christmas. I had a budget (roughly based on how good I’d been that year) and a deadline (Christmas shopping), and I then had to put forward a business case (Christmas list). I’d embellish this business case with facts about the toys I most wanted. This was made easier by Argos because they’d listed the features from the side of the toy’s box: “With realistic laser canon sounds”, “operating tipper wagons”, “TV AM’s resident rodent superstar” and so on. So, I was glad to discover that choosing and justifying a Juniper SRX is nearly as easy.
Usually if a network device has its features written on the side of the box, you’d only ever want it on your broadband at home. But what if someone made an affordable device which could service your home or small office, runs Junos, has a stateful firewall, switchports and most of the protocols you’ve grown up with, wouldn’t you put that on your Christmas list? “SRX100 - want!”
Over the past year we’ve rolled out over 700 SRX210s, and I’ve grown to like them. MLL Telecom are technology agnostic meaning the SRX210 was chosen for its combination of features, extendibility and price. The SRX210 has 8 switchports, a gigabit uplink, a WIC style expansion slot called a PIM (for an ADSL/3G card), and all the features listed above. Because of this versatility we can use the same device with any of our uplink technologies (EAD, MPF, ADSL, even 3G). The SRX100 is similar, but with a fast Ethernet uplink port and no ADSL (you’ll need an SRX110 for that).
Admittedly you’d need to have been pretty well behaved this year to get an SRX210 for Christmas (they’re more of a small branch office spec), but if you were building a home lab then a couple of SRX100s would be a lot easier to get past the wife than an M160 off eBay.
With the SRX branch devices you still get a separate routing engine and forwarding engine, but the forwarding engine is running in software using a real-time thread. This enables a number of things to happen including Junos RPM (Real-time Performance Monitoring) with hardware time stamping (more on that in another blog post).
The SRX Series origins lie in taking the best design elements of the ScreenOS platform and then merging them into Junos, and taking the features from the J-Series routers and adding some extras. Several years ago the J-Series was given flow-mode operation, which at the time was unpopular due to memory utilisation issues alongside BGP. Flow mode can be turned off if you wish, and the SRX will operate as a standard packet mode device, but that might not be the best use of this hardware. Rather than have either-or, however, you can also configure an SRX to filter off packet mode traffic from the default flow mode processing path, giving you the best of both worlds.
What flow mode does give you is a stateful firewall, Intrusion Detection and Prevention (IDP), and Application-Layer Gateway (ALG), antivirus, anti-spam and web filtering. That’s most of the firewall features you previously had to do in a separate device. It can also terminate IPSEC VPNs. We’ve terminated nearly 200 IPSEC VPNs into two SRX650s (SRX210s on the remote end, naturally) for our off-net customers.
Traffic segregation can be enabled per-interface by using VLANs, but it can do better than that. Zones allow you to segregate interfaces into groups, e.g. Trusted, Untrusted, DMZ, and apply policy on the transit of data between those zones. You can also segregate routing information using routing instances. Even on an SRX100. This is ideal for RPM, where a probe can be configured in each VPN while the SRX only carries a default route for each, effectively turning one box into several.
Because the SRX runs Junos it can do BGP (table size permitting). The SRX650 has specific features to do BGP Route Reflection. Some caution has to be taken with the limits of both the forwarding and routing tables, but it’s certainly useful for experimentation in lab environments, and can provide BGP to remote sites over IPSEC.
The SRX100 might seem expensive when compared with a low-end Linksys E4200 or a Netgear FVS318G, but it packs in a full Junos device capable of many things you wouldn’t expect in a device this size. With full SNMP, Radius, NTP, OSPF, ISIS and of course IPv6, you have many of the features you’ve grown to know on the M-Series and MX-Series, but available on something you could stick on your home broadband. It fits in a stocking, too!
Although I’m starting to sound like an advert, I’m genuinely very happy with the SRX. I’d like to know your thoughts and experiences with the SRX series and would welcome your feedback, thanks.
