17.7 Legacy Series / OpenVPN Issues
December 26, 2017, 04:54:07 PM
Hello All,

Until recently, OpenVPN has been running great on my PC Engines APU device flawlessly. Now though, the tunnel gets really spotty whenever data is sent over it...

If I'm running a ping, ping times will be 60-90ms and MTR shows good, reliable traces between my laptop and endpoints both on the network behind the OPNSense router, and through tunnel and out onto the internet.

If, however, data is requested ping times jump to 4-12 SECONDS and 50% or more of them are dropped. Once the data requested has trickled in the tunnel re-stabilizes and all is well.

Obviously, when the tunnel is moving data some drop off in the ping performance is expected but this is far beyond that. The tunnel is all but useless now, and I'm not even sure where to look for issues. Beyond updates, the OPNSense side has not changed at all... nor has the client side. It's the same laptop that was running perfectly a few weeks ago.

I've tried making a connection from other locations and other types of connections but the performance is the same. If I make a connection from my office, my cell phone... my parents house, etc., I can create the tunnel and ping without issue but when I try to load a web page, or make an SSH connection across the tunnel, performance drops off a cliff.

Any idea where I can look to track this down? Load averages on the router are very low (.10 to .20 usually), and I'm running the latest 17.7.11 version of OPNSense.. and I rebooted just this AM, but it didn't make a difference. I'm trying to parse through the recently changes to OpenVPN through OPNSense updates but nothing is jumping out at me...

Any help would be most welcome!

Hardware and Performance / Understanding Storage Needs
February 18, 2016, 04:00:45 PM
Hello,

(This may belong in Hardware...)

I've placed an order this week for an APU2C4 (http://www.pcengines.ch/apu2c4.htm) which I am going to use for OPNSense. Having running pfSense for many years across a broad range of hardware I was surprised to see OPNSense wanted a 120GB+ SSD for an ideal setup and I'm curious to understand why. The largest storage I ever installed with pfSense was 4GB.

This will be my first hardware OPNSense router and will be installed in my home, handling nothing more taxing than a couple of port forwards and being an OpenVPN server so my concern isn't necessarily with this project; I'm more broadly curious.

Can I expect success with a 4GB mSATA drive or should I buy something larger? Is the 120GB recommendation in place to ensure long term durability with log writes? Is it in place to handle the storage needs of a large business using OPNSense for squid? Does OPNSense do something with storage that, for instance, pfSense doesn't do?

If I decide to move the routing hardware at my company over to OPNSense as well, but I don't enable squid, or captive portals, will I ever need more than 4GB of storage? The hardware recommendations page seems to increase the hardware requirements in lockstep assuming that both the user base and feature set grows and I'm curious to understand where I can expect to see my storage needs grow..

Thanks for your time,
