2020-05-19nat: do not report unassigned IP address for DNATChristian Poessinger
That warning made no sense as the destination address where we forward a port to is by design not locally connected.

2020-05-19dhcpv6-pd: T421: support ethernet based interfacesChristian Poessinger
Add support for prefix delegation when receiving the prefix via ethernet, bridge, bond, wireless.
2020-05-19configdict: T2372: interfaces must reuse interface_default_dataChristian Poessinger
This is to remove the amount of duplicated entries in dictionaries. It's one more part to move to a unified interface management.
2020-05-19T2465: vyos-hostsd-client needs sudokroy-the-rabbit
There have been a number of complaints about DHCP not getting inserted into the `/etc/hosts` file. This should correct that problem.

Dictionary is used to remove the amount of duplicated code by e.g. ethernet or bridge interface.

It allows IP protocol numbers 0-255, protocol names e.g. tcp, ip, ipv6 and the negated form with a leading "!".
2020-05-16nat: T2198: use Jinja2 macro for common ruleset for SNAT and DNATChristian Poessinger
By using a Jinja2 macro the same template code can be used to create both source and destination NAT rules with only minor changes introduced by e.g. the used chain (POSTROUTING vs PREROUTING). Used the following configuration for testing on two systems with VyOS 1.2 and the old implementation vs the new one here. set nat destination rule 15 description 'foo-10' set nat destination rule 15 destination address '1.1.1.1' set nat destination rule 15 inbound-interface 'eth0.202' set nat destination rule 15 protocol 'tcp_udp' set nat destination rule 15 translation address '192.0.2.10' set nat destination rule 15 translation port '3389' set nat destination rule 20 description 'foo-20' set nat destination rule 20 destination address '2.2.2.2' set nat destination rule 20 destination port '22' set nat destination rule 20 inbound-interface 'eth0.201' set nat destination rule 20 protocol 'tcp' set nat destination rule 20 translation address '192.0.2.10' set nat source rule 100 outbound-interface 'eth0.202' set nat source rule 100 protocol 'all' set nat source rule 100 source address '192.0.2.0/26' set nat source rule 100 translation address 'masquerade' set nat source rule 110 outbound-interface 'eth0.202' set nat source rule 110 protocol 'tcp' set nat source rule 110 source address '192.0.2.0/26' set nat source rule 110 source port '5556' set nat source rule 110 translation address 'masquerade' set nat source rule 120 outbound-interface 'eth0.202' set nat source rule 120 protocol 'tcp_udp' set nat source rule 120 source address '192.0.3.0/26' set nat source rule 120 translation address '2.2.2.2'

2020-05-16nat: T2198: sync generated SNAT rules with VyOS 1.2Christian Poessinger
The generated NAT rules in VyOS 1.2 are compared to the generated nftables ruleset in VyOS 1.3 this was done by converting the 1.2 iptables ruleset to nftables and then do the diff. To convert from iptables to nftables use the following command: $ iptables-save -t nat > /tmp/tmp.iptables $ iptables-restore-translate -f /tmp/tmp.iptables The following CLI options have been used for testing: set nat source rule 10 description 'foo-10' set nat source rule 10 destination address '1.1.1.1' set nat source rule 10 destination port '1111' set nat source rule 10 exclude set nat source rule 10 log 'enable' set nat source rule 10 outbound-interface 'eth0.202' set nat source rule 10 protocol 'tcp_udp' set nat source rule 10 translation address '192.0.2.10' set nat source rule 15 description 'foo-10' set nat source rule 15 destination address '1.1.1.1' set nat source rule 15 exclude set nat source rule 15 log 'enable' set nat source rule 15 outbound-interface 'eth0.202' set nat source rule 15 protocol 'tcp_udp' set nat source rule 15 translation address '192.0.2.10' set nat source rule 20 description 'foo-20' set nat source rule 20 destination address '2.2.2.2' set nat source rule 20 log 'enable' set nat source rule 20 outbound-interface 'eth0.201' set nat source rule 20 protocol 'tcp' set nat source rule 20 translation address '192.0.2.10' set nat source rule 100 outbound-interface 'eth0.202' set nat source rule 100 protocol 'all' set nat source rule 100 source address '192.0.2.0/26' set nat source rule 100 translation address 'masquerade'

2020-05-16nat: T2198: migrate "show nat" commands to XML and PythonChristian Poessinger
- "show nat source|destination statistics" is now implemented in Python - "show nat source|destination rules" needs a new implementation, see T2459 - "show nat source|destination translations" has been copied over from the old repo and is here until it is rewritten, this was not possible for "rules" as there would have been too much dependencies. This one only requires libxml-simple-perl

2020-05-16nat: T2198: automatically determine handler numbersChristian Poessinger
When instantiating NAT it is required to isntall some nftable jump targets. The targets need to be added after a specific other target thus we need to dynamically query the handler number. This is done by get_handler() which could be moved to vyos.util at a later point in time so it can be reused for a firewall rewrite.
