Letsencrypt expired, and dns errors


#81

I will be traveling as well today…

I do have DNS override setting on OpnSense, so that internal PC to access box… will have internal IP response, not a public IP. In essence, it is kind of alternative for NAT reflection?


#82

https://dablog.informafix.net/204
NAT Reflection employs some simple bouncing daemons to redirect the connections, which works but isn’t always desirable, or even functional for some scenarios. Usually, split DNS is the better way if it is possible on your network. Both are explained here.


#83

will try a test at later time though…tks


#84

Maybe. I’d try that, or another option if opnSense has it, is to drop the MiaB into a DMZ. pfSense calls it 1to1 NAT. I have 5 public IPs, so I have played around with it, but perfer to keep MiaB on the same vlan as my other VMs.

Just responding to your last message here as well. I know NAT Reflection is a poor way to do this and split DNS is better, but I have it working good enough. Maybe someday I’ll dig down and try out split DNS, but this MiaB serves some of my clients email domains, and I try not to break stuff too often :slight_smile:

Oh, I was digging around and noticed I had made some changes to the DNS server on pfSense to forward DNS queries onto my upstream DNS servers. I remember I had issues with getting VMs on the same vlan to resolve my public domain if that is not enabled.


#85

my MAIB is on DMZ…


#86

Ok. The only thing left is the NAT Reflection or split DNS. Lets go down that road and see if that gets you fixed up.


#87

hi cwilkins,

I tried both PureNAT on/off and still saw nothing changed… Here’s some tcpdump on two boxes (MAIB at DMZ and OPNsense) while I was doing CERT renew. Any thoughts?

BTW, I have my Domain Registra setting up proper for my glue records (ns1.box.f2f10.com and ns2.box.f2f10.com) and I have set under domain registra’s webpannel correctly my Name Server are above mentioned. My Reverse domain record is set up properly with my ISP as well…

#94

now, question is, what difference between openWRT and openSense (pfSense) that make MAIB works fine in DMZ with openwrt, but not with opnSense???


#95

it looks like that my openWRT Port Forwarding all have “nat loop back” enabled, which is NAT Reflection…


#96

now, i probably , need proper NAT reflection to work on opensense…


#97

after enabling NAT Reflectin in openSense…

Status Checks Incorrect
#98

It looks like that it’s not resolved issue yet even with NAT Reflection enabled on OpnSense, while NAT Loopback works fine with OpenWRT…???////

Anyone with OpnSense + MAIB setting that works? Thanks in advance…


#99

with NAT Reflectin enabled, it seems that my email client from internal network can access MAIB with no issues. Therefore I don’t need to enable Split DNS for that for now. However, MAIB status check still doesn’t work…


#100

Ok, on openwrt, I have the following configuration in Firewall and with NAT Loopback enabled for incoming port forwarding…
