Hi Gray and welcome to the IPFire Community!
For the short term, please go to the Intrusion Prevention System (menu Firewall > Intrusion Prevention System) and make sure it is set to STOPPED. It can be enable/started when we get things working.
Please include a screenshot of the Domain Name System webpage (menu Network > Domain Name System).
I tried the 71.243.0.12 DNS server and I get an error. Maybe it doesn’t like me since I am not on the Verizon network (I can ping the address). So for now, let’s stick with the Google DNS.
[root@ipfire ~]# dig +dnssec ipfire.org @71.243.0.12
; <<>> DiG 9.11.21 <<>> +dnssec ipfire.org @71.243.0.12
;; global options: +cmd
;; connection timed out; no servers could be reached
[root@ipfire ~]# dig ipfire.org @71.243.0.12
; <<>> DiG 9.11.21 <<>> ipfire.org @71.243.0.12
;; global options: +cmd
;; connection timed out; no servers could be reached
My DNS page take about the same (8-9 seconds). It may be dependent on how many servers added. I have twelve added.
No bitcoin mining. I’d be pretty pissed unhappy if that was true!
