Barracuda NG Firewalls - Can They Replace My Barracuda 410 Web Filter?

Love Ubiquity!

One consideration is doing web filtering behind the firewall. I am of the opinion that router and firewall functions go in the outward facing appliance, filtering and proxying go behind that at a different layer for security, performance and flexibility reasons.
I would look at Ubiquiti as a replacement for the Cisco and using something else, maybe continuing to use a Barracuda web filter, for the web filtering. Using a Barracuda in a position where it is secured by something more serious like the Ubiquiti would mean that it was protected from being blatantly opened to the outside world.
How easy are the Ubiquiti firewalls for someone who isn't a CLI guru with Cisco and the like?
For the ER-X and ERL, you simply
- pre-download the latest firmware
- plug in power
- plug in your laptop configured with 192.168.1.2 to eth0
- pop the web browser to 192.168.1.1.
- load the updated firmware
- reboot
- run the WAN+2LAN2 wizard to setup the router
- plug your internet into eth0
a. Reboot your cable modem if you have one of those because they lock to MAC address - plug your local switch into eth1
- win

A huge upside to Ubiquit is that you could get one for home and work with the same features and interface in your home environment so that you can mess around and test things without needing to do it on the product system. @anonymous has the baby Ubiquiti at home which is around $50. I have the older smallest one which is around $90 and we travel with it to use wherever we go.
The ERX is the much better unit for a SOHO environment because of the built in switching chip.
The ERL is a 100% router. None of the ports have an onboard switch so if you bridge eth1 and eth2, you will lose performance there.

What do you use for client VPN connections to the EdgeRouters?

The Windows clients work fine, L2TP.

Is the authentication using RADIUS, or are you setting up user accounts for client VPN access inside the EdgeRouter itself? I know Cisco works either way, but I was not sure about Ubiquiti.
-
You can use OpenVPN, too. For client connections.

All my site to site links are currently OpenVPN but IPSEC can be offloaded and thus can get higher throughput than OpenVPN.
OpenVPN is limited to ~10mbps simply due to processing power of the ERL.
I have seen people post results of IPSEC tunnels properly offloaded getting more than 100mbps.

I just set up accounts in the ER. We only have a couple people using the VPN, so it was less work.

Not easily on either Windows or the ERL.
In the ERL L2TP is available in the GUI and is natively available to Windows.
OpenVPN requires third party software on Windows as well as requiring advanced command line setup on the ERL.
Once someone has experience with the ERL it is not very hard, but it is not basic.

Love my Edge Router X

There's no limit on VPN clients or VPN peers that I could see from the datasheets. Can someone confirm that for me, please? Would you put one of these at the hub of a hub and spoke like my setup (getting close to 10 remote peers) and expect it to perform well?

Of course there are no artificial limits because there is no licensing.
There may well be limits due to hardware, but I have about 15 OpenVPN tunnels connecting from my house to various client routers and colo routers, etc. So no idea what real world limits might exist.

No limits. Welcome to the glorious world of quality, enterprise, open source goodness. A vendor who works by making good products instead of slick marketing ads to management.
Not only will it work well, it will kick the crap out of the Cisco. If the Cisco can do it, the Ubiquiti can do much more. This is much more robust hardware.

And I believe you have an ERL, the little unit, not the Pro which has a bit more memory and CPU, right? The horsepower on the ERP is a lot more, and it rackmounts.
Plus OpenVPN uses a lot more overhead than IPSec. So moving to IPSec and/or the ERP would do a lot for the potential VPN connection ceiling.

OpenVPN cannot be offloaded to a dedicated chip like IPSEC can. If you do not offload IPSEC the performance is similar.

I would never buy the ER Pro for any SMB. I just do not see the need. I am sure there is a special case out there, but it will certainly not be normal.
I generally recommend the ER-PoE for SMB offices so that they can have their UAP powered by the router without needed to buy an entire PoE switch. Also is the fact that the basic UAP and UAP-AC-LITE are passive PoE and many PoE switches do not support that.

In addition to the Barracuda NG series, I am looking at one of the Sophos UTMs that include web application control. There's a newer model Cisco ASA that has this as well.
Each of those solutions is not cheap as we all know, so the ERL is certainly a contender here for a small office we're about to light up in the coming weeks. Does anyone here think an ERL would have trouble connecting back to by ASA 5510 at HQ using an IPSec tunnel? I believe we're using IKEv1 on the ASA 5510 and its ASA 5505 peers right now. For about $100 or a little less, I'd be willing to at least do some R and D and try it but wanted to know if anyone here had connected the ERL to a different OEM's device successfully.
-
I feel like someone has tested the Ubiquiti to Cisco ASA functionality but I can't remember who.
-
Even Cisco has not screwed up IPSEC stands. It will work just fine.
If you want a test, I can do a screen share and we can connect up to one of mine to proof it.
