2021-07-17VRF: T3655: proper connection tracking for VRFszsdc
Currently, all VRFs share the same connection tracking table, which can lead to problems: - traffic leaks to a wrong VRF - improper NAT rules handling when multiple VRFs contain the same IP networks - stateful firewall rules issues The commit implements connection tracking zones support. Each VRF utilizes its own zone, so connections will never mix up. It also adds some restrictions to VRF names and assigned table numbers, because of nftables and conntrack requirements: - VRF name should always start from a letter (interfaces that start from numbers are not supported in nftables rules) - table number must be in the 100-65535 range because conntrack supports only 65535 zones
2021-06-26nat: T1083: fix Jinja2 templating errorChristian Poessinger
Commit 166d44b3 ("nat: T1083: add translation options for persistent/random mapping of address and port") added support for persistent IP address and port mappings for NAT. Unfortunately one if clause got lost in translation.

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.
2020-11-28vyos.template: T2720: fix remaining in-line time_block syntaxChristian Poessinger
Commit a2ac9fac ("vyos.template: T2720: always enable Jinja2 trim_blocks feature") globally enabled the trim_blocks feature. Some templates still used in-line trim_blocks "{%"- or "-%}" which caused miss-placed line endings. This is fixed by removing all in-line trim_block statememnts of Jinja2 templates.
2020-10-05nat: T2951: use proper comments for source/destination loggingChristian Poessinger
For both source and destination NAT always the LOG name contained DST - which is definately false. This has been corrected to use SRC and DST on the appropriate rules.

2020-06-14nat: T2593: fix for SNAT translation port when using masqueradeChristian Poessinger
The "to" qualifier did not get rendered when using source ports in masquerade targets. This case was totally missed out when porting.
2020-06-12nat: T2571: add special handling for negated source/destination port(s)Christian Poessinger
We specify NFT source/destination ports within a { } group, but if the port range in question is negated, we need to move the != fraction out of { } and infront of that group, else NFT loading will fail big time.

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'

CLI commands used for ruleset generation: 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'
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'
