Network issue

[Dima Sokolov]

Hello Christian,

I made some tests, and Cloudflare 1.1.1.1 works fine.

Test 1:
Setting the router's primary DNS server to Cloudflare 1.1.1.1 with Sculpt 20.08 default network settings in Virtualbox
Using Falkon to browse the Internet

The relevant /config/nic_router:
<config verbose_domain_state="yes">
  <report interval_sec="5" bytes="yes" config="yes" config_triggers="yes"/>
  <default-policy domain="default"/>
  <uplink label="wired" domain="uplink"/>
  <domain name="uplink">
    <nat domain="default" tcp-ports="1000" udp-ports="1000" icmp-ids="1000"/>
  </domain>
  <domain name="default" interface="10.0.1.1/24">
    <dhcp-server ip_first="10.0.1.2" ip_last="10.0.1.200" dns_server_from="uplink"/>
    <tcp dst="0.0.0.0/0">
      <permit-any domain="uplink"/>
    </tcp>
    <udp dst="0.0.0.0/0">
      <permit-any domain="uplink"/>
    </udp>
    <icmp dst="0.0.0.0/0" domain="uplink"/>
  </domain>
</config>

Test 1 result: Network is fully operational.

Test 2:
Setting the primary DNS server to 1.1.1.1 from Sculpt 20.08 in Virtualbox while the router has a different primary DNS server (Cloudflare 1.0.0.1)
Using Falkon to browse the Internet

The relevant /config/nic_router:
<config verbose_domain_state="yes">
  <report interval_sec="5" bytes="yes" config="yes" config_triggers="yes"/>
  <default-policy domain="default"/>
  <uplink label="wired" domain="uplink"/>
  <domain name="uplink">
    <nat domain="default" tcp-ports="1000" udp-ports="1000" icmp-ids="1000"/>
  </domain>
  <domain name="default" interface="10.0.1.1/24">
    <dhcp-server ip_first="10.0.1.2" ip_last="10.0.1.200" dns_server="1.1.1.1"/>
    <tcp dst="0.0.0.0/0">
      <permit-any domain="uplink"/>
    </tcp>
    <udp dst="0.0.0.0/0">
      <permit-any domain="uplink"/>
    </udp>
    <icmp dst="0.0.0.0/0" domain="uplink"/>
  </domain>
</config>

Test 2 result: Network is fully operational.
