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'
```
|
|
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

Remove `service upnp` as it never worked as expected, nft rules do
not integrated and custom patches do not seem like a suitable
solution for now.
Security:
UPnP has been historically associated with security risks due to its automatic
and potentially unauthenticated nature.
UPnP devices might be vulnerable to unauthorized access or exploitation.

ethernet: T6306: add support for EVPN MH uplink/core tracking
|
|
|
|
When all the underlay links go down the PE no longer has access to the VxLAN
+overlay.
To prevent blackholing of traffic the server/ES links are protodowned on the PE.
A link can be setup for uplink tracking via the following configuration:
set interfaces ethernet eth0 evpn uplink

bgp: T6189: L3VPN connectivity is broken after re-enabling VRF
|
|
After e7bb65894 ("vrf: T6189: render FRR L3VNI configuration when creating VRF
instance") we need to ensure that the VRF L3VNI configuration is removed in FRR
prior to removing the BGP VRF instance.
The reason is [1] where FRR only allows VRF BGP instance to be removed when
there is NO VNI configured anymore.
1: https://github.com/FRRouting/frr/blob/064c3494527b9e84260410006768ed38e57e1de7/bgpd/bgp_vty.c#L1646-L1650
|
|
When adding and removing VRF instances on the fly it was noticed that the vni
statement under the VRF instance in FRR vanishes. This was caused by a race
condition which was previously designed to fix another bug.
The wierd design of a Python helper below the VRF tree to only generate the
VNI configuration nodes is now gone and all is rendered in the proper place.

pppoe-server: T6234: PPPoE-server pado-delay refactoring
|
|
We have several config XML definitions that use the same python3
script `system_host-name.py`
https://github.com/vyos/vyos-1x/blob/current/interface-definitions/system_name-server.xml.in
https://github.com/vyos/vyos-1x/blob/current/interface-definitions/system_host-name.xml.in
https://github.com/vyos/vyos-1x/blob/current/interface-definitions/system_static-host-mapping.xml.in
https://github.com/vyos/vyos-1x/blob/current/interface-definitions/system_domain-name.xml.in
https://github.com/vyos/vyos-1x/blob/current/interface-definitions/system_domain-search.xml.in
Any change in these scripts calls to restart the `service snmpd`
The service `snmpd` should be restarted only if `host-name` or
`domain-name` was changed.
It is a good idea to rewrite it to `get_config_dict` in the future.

T6267: Check interface wireless module before apply config

Check if the wireless device/modem exists in the system and the
module `ieee802111` was loaded
In cases where we do not have wireless devices, it prevents the
unexpected traceback
```
set interfaces wireless wlan0 address 192.0.2.5/32

T6221: Return default ip rule values after deleting VRF

Fix for restoring default ip rule values after deleting VRF
Defult values:
```
$ ip rule

32766: from all lookup main
32767: from all lookup default
```
After adding and deleting a VRF we get unexpected values:
```
$ ip rule

2000: from all lookup [l3mdev-table] unreachable
32765: from all lookup local

T5169: Add PoC for generating CGNAT rules rfc6888
|
|
|
|
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'
```
