2022-08-29nat: T4367: Move nat rules from /tmp to /run/nftables_nat.confViacheslav Hletenko
Move nftables nat configuration from /tmp to /run As we have for other services like firewall, conntrack Don't remove the config file '/run/nftables_nat.conf' after commit
2022-08-17nat: T538: Add static NAT one-to-oneViacheslav Hletenko
Ability to set static NAT (one-to-one) in one rule set nat static rule 10 destination address '203.0.113.0/24' set nat static rule 10 inbound-interface 'eth0' set nat static rule 10 translation address '192.0.2.0/24' It will be enough for PREROUTING and POSTROUTING rules Use a separate table 'vyos_static_nat' as SRC/DST rules and STATIC rules can have the same rule number

2022-04-10nat: T2199: bugfix dry-run newly generated config before installChristian Poessinger
Commit bb76e8d7f1635 ("nat: T2199: dry-run newly generated config before install") added support to verify the generated nftables ruleset. Unfortunately if the verify failed - a Python exception was triggered: NameError: name 'nftables_ct_file' is not defined This was due to bad copy/pasting.
2022-01-10nat: T2199: dry-run newly generated config before installChristian Poessinger
Before installing a new conntrack policy into the OS Kernel, the new policy should be verified by nftables if it can be loaded at all or if it will fail to load. There is no need to load a "bad" configuration if we can pre-test it.

2021-01-19nat: T2947: add many-many translationChristian Poessinger
Support a 1:1 or 1:n prefix translation. The following configuration will NAT source addresses from the 10.2.0.0/16 range to an address from 192.0.2.0/29. For this feature to work a Linux Kernel 5.8 or higher is required! vyos@vyos# show nat source { rule 100 { outbound-interface eth1 source { address 10.2.0.0/16 } translation { address 192.0.2.0/29 } } } This results in the nftables configuration: chain POSTROUTING { type nat hook postrouting priority srcnat; policy accept; oifname "eth1" counter packets 0 bytes 0 snat ip prefix to ip saddr map { 10.2.0.0/16 : 192.0.2.0/29 } comment "SRC-NAT-100" }

2020-11-28nat: T3092: migrate to get_config_dict()Christian Poessinger
The NAT system consists out of nested tag nodes which makes manual parsing very hard. This is a perfect candidate for migrating this to get_config_dict() as there is already a smoketest in place. In addition this should make it easier to add features like static nat/hairpin.

2020-08-28nat: T2813: translation address is mandatory if rule is not excludedChristian Poessinger
2020-07-25vyos.util: add common helper to load kernel modulesChristian Poessinger
l2tpv3, wireguard, wirelessmodem, nat all require additional Kernel modules to be present on the system. Each and every interface implemented their own way of loading a module - by copying code. Use a generic function, vyos.util.check_kmod() to load any arbitrary kernel module passed as string or list.
2020-07-19nat: T2709: remove 'translation address' mandatory checkJernej Jakob
Rules without a translation address are also valid, they'll modify just the port and leave the address intact. This also used to be a valid syntax and it caused an error on upgrade.
