Openwrt 18.06 on RPi with hnet protocol internally, dhcp externally. Router is an edge device. Some of the clients will be IPv4 only so need an IPv4 address, but I can't work out the config options to give them one. By setting ip4mode to 'on' in the 'pa' section of /etc/config/hnet I can get IPv4 addresses on the router's internal interfaces but no addresses are given to the downstream IPv4 clients. If I set ip4mode to the default of 'ifuplink' I don't even get IPv4 addresses on the router's internal interfaces. wireshark shows DHCP Discover requests from the clients but never any replies.
/etc/config/hnet contains
config pa pa
# option ip4prefix 10.0.0.0/8
option ip4mode on
# option ulaprefix fd12:3456:789A::/48
# option ulamode off
option persistent_store /etc/hnet-pa.store
/etc/config/network contains
...
config interface 'eth1'
option proto 'hnet'
option ifname 'eth1'
option ip6assign '62'
option ipv6 '1'
option dnsname 'hnet-eth1'
...
ifconfig shows that eth1 has an IPv4 address 10.0.111.52 along with GUA, ULA and LL addresses.
Clients only have GUA, ULA and LL addresses but no IPv4 address.
