Restore "default" behavior from ipsec.conf
|
|
|
|
|
|
|
|
IKE lifetime is life_time, and ESP lifetime is rekey_time.
|
|
Commit 7a873eb6 ("ipsec: T3764: bugfix missing IKE and ESP lifetime values")
re-added the lost in translation IKE/ESP rekey values. But it did not specify
the unit, which is s(econd).
|
|
During the migration the IKE and ESP key/re-key lifetime settings got lost in
translation. This is now fixed and the values/defaults correspond to VyOS 1.3.

Connection uniqueness policy to enforce. To avoid multiple connections from the
same user, a uniqueness policy can be enforced.
* never: never enforce such a policy, even if a peer included INITIAL_CONTACT
notification
* keep: reject new connection attempts if the same user already has an active
connection
* replace: delete any existing connection if a new one for the same user gets
established
To compare connections for uniqueness, the remote IKE identity is used. If EAP
or XAuth authentication is involved, the EAP-Identity or XAuth username is used
to enforce the uniqueness policy instead.

Remote access IP pools can now be defined at a global level and referenced
in IPSec remote-access connections. To defined a pool use:
set vpn ipsec remote-access pool global-ipv4 name-server '172.16.1.1'
set vpn ipsec remote-access pool global-ipv4 prefix '192.168.0.0/24'
set vpn ipsec remote-access pool global-ipv6 name-server '2001:db8::1'
set vpn ipsec remote-access pool global-ipv6 prefix '2001:db8:1000::/64'
A connection can then reference the pool:
set vpn ipsec remote-access connection foo pool 'global-ipv4'
set vpn ipsec remote-access connection foo pool 'global-ipv6'

... this enables a dual-stack IKEv2 VPN deployment.

update to use PKI.
|
|
|
|
- Adds client/server authentication methods.
- Adds basic verification to remote-access.
- Adds DHCP pool and options to remote-access.
- Cleanup unused PKI files.
|
|
Used by both site2site and remote-access/road-warrior VPN connections.

VyOS has a known to work mechanism in supplying CLI default values into the
Python configuration scripts. This commit removes hardcoded default values from
the Jinja2 template and places them into the appropriate XML definitions.
The big advantage is that the default value itself and the corresponding help
string are located in the exact same file.
|
|
Commit 2d79a500 ("ipsec: T2816: add Jinja2 converter for ESP/IKE groups to
string") added a Jinja2 helper function which can be used to transform VyOS CLI
ESP and IKE key proposals into a strongSwan compatible string cipher.
This commit changes the IPSec implementation to make use of this new Jinja2
filter fubction/Python helper. This is required base work for better automated
tests (smoketests) but also for an IKEv2 road-warrior setup.

XFRM interfaces are similar to VTI devices in their basic functionality but
offer several advantages:
* No tunnel endpoint addresses have to be configured on the interfaces.
Compared to VTIs, which are layer 3 tunnel devices with mandatory endpoints,
this resolves issues with wildcard addresses (only one VTI with wildcard
endpoints is supported), avoids a 1:1 mapping between SAs and interfaces, and
easily allows SAs with multiple peers to share the same interface.
* Because there are no endpoint addresses, IPv4 and IPv6 SAs are supported on
the same interface (VTI devices only support one address family).
* IPsec modes other than tunnel are supported (VTI devices only support
tunnel mode).
* No awkward configuration via GRE keys and XFRM marks. Instead, a new identifier
(XFRM interface ID) links policies and SAs with XFRM interfaces.

selectors, and selectors with VTI.
