This package adds scripts for xfrm interfaces support.
Example configuration via /etc/config/network:
config interface 'xfrm0'
option proto 'xfrm'
option mtu '1300'
option zone 'VPN'
option tunlink 'wan'
option ifid 30
config interface 'xfrm0_static'
option proto 'static'
option ifname '@xfrm0'
option ip6addr 'fe80::1/64'
option ipaddr '10.0.0.1/30'
Now set in strongswan IPsec policy:
if_id_in = 30
if_id_out = 30
