2024-05-28T6411: CGNAT fix sequences for external address rangesViacheslav Hletenko
Fix the bug where address external alocation was not rely on sequences of the external IP addresses (if set)
2024-05-18T5169: Allow to set CGNAT multiple internal poolsViacheslav Hletenko
Allow to set multiple CGNAT internal pools ``` set nat cgnat pool internal int-01 range '100.64.0.0/28' set nat cgnat pool internal int-01 range '100.64.222.11-100.64.222.14' ```
2024-05-18T6364: CGNAT drop hard limit that allows only one translation ruleViacheslav Hletenko
As PoC for CGNAT had a hard limit of using only one translation rule for one internal pool. Drop this limit and extend the usage number of the rules. ``` set nat cgnat rule 100 source pool 'int-01' set nat cgnat rule 100 translation pool 'ext-01' set nat cgnat rule 120 source pool 'vyos-int-02' set nat cgnat rule 120 translation pool 'vyos-ext-02' ```

T6351: CGNAT add verification if the pool exists

Add verification if the external/internal pools are exists before we can use them in the source and translation rules

2024-04-09T5169: Add PoC for generating CGNAT rules rfc6888Viacheslav Hletenko
Add PoC for generating CGNAT rules https://datatracker.ietf.org/doc/html/rfc6888 Not all requirements are implemented, but some of them. Implemented: REQ-2 ``` A CGN MUST have a default "IP address pooling" behavior of "Paired" CGN must use the same external IP address mapping for all sessions associated with the same internal IP address, be they TCP, UDP, ICMP, something else, or a mix of different protocols. ``` REQ-3 ``` The CGN function SHOULD NOT have any limitations on the size or the contiguity of the external address pool ``` REQ-4 ``` A CGN MUST support limiting the number of external ports (or, equivalently, "identifiers" for ICMP) that are assigned per subscriber ``` CLI: ``` set nat cgnat pool external ext1 external-port-range '1024-65535' set nat cgnat pool external ext1 per-user-limit port '1000' set nat cgnat pool external ext1 range 192.0.2.222/32 set nat cgnat pool internal int1 range '100.64.0.0/28' set nat cgnat rule 10 source pool 'int1' set nat cgnat rule 10 translation pool 'ext1' ```
