      The new, unreleased Unifi UXG Pro just arrived here at the NTG Dallas offices. Woot! It's dual power supply, dual WAN, dual LAN, touch screen LCD and up and running!

      More details as we get to play with it.

      DAMN IT!!!

      As I said - we do have FQDN.
      I was just suprised when @Dashrender said they are free from Cloudflare

      I misspoke, I never meant that registered domains themselves were free. What I meant was free was DNS hosting and base level proxying from CF.

      @DustinB3403 said in Documenting Firewall Exceptions and Rules:

      I had to add some rules to a CentOS 8 server because some things stopped working that were previously working. (Not sure why this worked before, but it did)

      Adding a few rich rules resolved the issue immediately.

      None of this makes any sense. It's deny all and permit by exception. Why would you do anything else?

      That's the default, and that's what was working just fine for a long time. Suddenly it began "not working" and needed the exceptions made.

      A proper DMZ is still a valid concept, but was never that big of a deal. There are almost no resources that make sense to put there. If you have those resources, then sure. But who does? The advent of cloud computing, cheaper colocation, better IT knowledge, etc. has led most shops to not try to make "internal/external" shared resources where one side is public and the other uses LAN security; and what little of that remains in need is generally addressed with VLANs in a slightly different way.

      @Jimmy9008 said in Cisco ASA:

      A and B can also RDP/ping devices sitting on C.

      If this is true, it's just a matter of rules/route allowing C back to A/B or a route specifically for C -> A/B.

      172.16.0.0 vlan… switch IP = 172.16.0.1, ASA = N/A, gateway on the vlan is 172.16.0.1 (the switch)

      this is legacy. What appears to happen is that the switch has 0.0.0.0 set to 192.168.50.10 (the ASA) on a vlan2. So, traffic from 172.16.0.0 hits the switch IP at 172.16.0.1, then hope out 0.0.0.0
      ^ I think its this that's causing the issue.

      This should be fine, this is what allows the C network to get to the internet

      so, when on the 172.16.0.0 network, the request goes to the switch's IP (172.16.0.1) which forwards it to 192.168.50.10 (the ASA), The ASA then doesn't have a rule allowing traffic from 172.16.0.0 to talk to 10.x, so it just dumps the traffic.

      At least that's what it looks like to me at this time.

      “C” network really?

      By default Debian comes with iptables. It will allowing everything but a normal Debian install have no services running.

      Run iptables -L to see the firewall rules.

      On Debian 10 the default is nftables.

      @mary said in Network Address Translation - CompTIA Network+ N10-007 Prof Messer:

      Is there any kind of slowdown when using just one port if you are getting a lot of traffic?

      No not really. The most commonly used ports are 80 and 443. They process quite a bit of traffic on your average workstation.

      In fact, most servers are designed to work with a single port or just a handful of ports open. For custom applications using a specific port makes it easier to troubleshoot issues and restricts non application traffic. Many apps are defaulting to 443 these days. Although, keep in mind SSL /TLS can operate on other ports.

      what about the Windows Defender, I mean the antivirus and the firewall of Windows They go hand in hand right?

      They go together as in they are both security components of the Windows operating system. But that's about the extent of it. They are both very good, they should both always be used, they are both for the purpose of security. But they are not actually associated other than in name.

      Looks like the ER‑8‑XG could also be a good fit if you prefer the EdgeRouter series over the Unifi stuff. Also slightly less expensive, and better performance.

      And ordered... we should have it on Monday.

      From the only vendor offering prime?

      @scottalanmiller said in ISP Failover with Cisco ASA:

      That's mostly true. But Cisco considers it real Cisco and it shows their view of themselves. And that, I always think, is important. Cisco doesn't seem themselves as an enterprise player. And I've been in sales meetings with Cisco and that definitely comes through when talking to them.

      That's not what I got from my sales conversations with them. They were very explicit about real Cisco and the lesser sub-brands.

      Having been at two huge banks that were burned by being willing to use UCS, Cisco and enterprise are two words I never put together. From networking to phones to servers, Cisco is consistently overpriced and underperforming.

      I absolutely loved UCS, even wrote the original oVirt/RHV plugin for the VMFEX cards. They were ahead of their time with those boxes, but the cloud pretty much killed everything really cool and advanced about HW

      @pmoncho said in Kerio Connect "license error: license exhausted, cannot allow another host":

      Based on the couple posts I have seen, each registered user can have five devices. So, if they have 30 devices, they need 6 user licenses. Did they add any extra devices lately?

      Easily, but more likely they just let their license expire.

      @Donahue said in Why I See UTMs As Generally Bad in the Current Market:

      The reason we went with Fortigate over an Edge router, is that the Edge router couldn't do the IPsec bandwidth we were trying to hit. But mine is an NGFW with UTM bundled in. Could there been some other product that I dont know of that would have been better in our case?

      ERL does nearly half of what you need...

      https://community.ubnt.com/t5/EdgeRouter/ERL-Performance-Testing-with-IPSec-VPN/m-p/1053799#M44593

      ER and ERPro are so much more powerful. The ER Pro has 2x the CPU power, and 4x the RAM. We'd expect it to be able to saturate your lines no problem. Of course that is "expect", but based on the ERL speeds, and that they run the same code, there is little doubt that it can push IPSec over 1Gig speeds.

      https://dl.ubnt.com/datasheets/edgemax/EdgeRouter_DS.pdf

      Your link is what convinced me not to use the ER pro. the Pro's will only do <500 mbps at full capacity, its in the link you posted.

      Where in it?

      Oh, I see. he mentions ER Pro in another post, then posts them without stating what they are in a thread on ERLs. VERY confusing.

      Something to keep in mind is NGFW. Ubiquiti and Meraki, for example, are NGFW.

      It looks like much of the market is already starting to cool on the UTM crazy and NGFW is taking off as the "next stage" of popular approaches. Basically a reversal of direction or marketing at least, even from the big players in the UTM space like Palo Alto, Fortinet, Cisco, etc.

      @gjacobse said in Security while Traveling -:

      Could something like this or similar be supplemental?

      Seems pretty silly.

      So here is the question....

      What threat do you perceive there being? How do you feel this device addresses that thread?

      I don't really see any threat in the first place, and so that makes it extra hard to know how to assuage your fears. But how this device is supposed to help, I'm really unsure.

      Can I just back up my er3 and upload it to the 4

      I believe so.

      I have never tried, but it should handle it because it only bring the /config folder in, and nothing in the hardware of the 3 vs 4 is all that different.

      To clarify, I have migrated from ERL to ER4 a couple times. But I manually migrate. I don’t try to restore the old config.
