Package: isc-dhcp-client
Version: 4.3.5-3+deb9u1
Severity: normal
Dear Maintainer,
I'm connected to my ISP via cable modem which uses an ethernet connection to my
router running debian. On that router, I run a dhclient to retrieve my public
ipv4 address.
Yesterday, my ISP decided to hand me the following parameters via DHCP:
inet 100.103.70.92/18 brd 255.255.255.255
(part of output from "ip addr")
default via 100.103.127.254 dev eth0
(part of output from "ip route")
which broke ipv4 for me. I manually removed the bogus broadcast address and
added the corresponding one in my subnet:
> ip addr del 100.103.70.92/18 dev eth0
> ip addr add 100.103.70.92/18 brd 100.103.127.255 dev eth0
> route add default via 100.103.127.254 dev eth0
which immediately made ipv4 work again.
IMHO, there should be an option in dhclient (or it should be the default?) to
map broadcast addresses (and gateway addresses?) which are outside of the
subnet into that subnet.
OTOH, I tried today to undo my changes (without rebooting my router) and ended
up with working ipv4 with this 255.255.255.255 broadcast address :-/
