Summary
Currently, the VPN network range used in Gardener is restricted to the hard-coded default values,
192.168.123.0/24
andfd8f:6d53:b97a:1::/120
. We propose to make this network range configurable to offer more flexibility to both operators and users. This is achieved by a new configuration option ingardener/gardener
andgardener/vpn2

Proposal
The proposal targets two projects:
gardener/gardener
andgardener/vpn2
.gardener/gardener
, configure VPN Network on Seed Level by introducing a new optional fieldSeed.spec.networks.vpn
, type*string
192.168.123.0/24
/fd8f:6d53:b97a:1::/120
)IPFamily
/24
(IPv4),/120
(IPv6)gardener/vpn2
, introduce a new environment variable for configuring the VPN network to use:VPN_NETWORK
/24
is split up into 4 equally-sized/26
