containers with network='filtered' cannot talk to each other

[Brian Parma]

In bug #807315, you say that two arkose containers with network='filtered' will be able to talk to each other as the host will route between them.

I tried using the simple:
con = ArkoseContainer(network='filtered')
con.run_command('bash')

and the host could ping both containers, the containers could ping the host, but they could not ping each other. I got Destination Host Unreachable.

the routing tables were:
# container 1: 169.254.1.2/8
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
169.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 eth0
0.0.0.0 169.254.1.1 0.0.0.0 UG 0 0 0 eth0

# container 2: 169.254.1.10/8
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
169.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 eth0
0.0.0.0 169.254.1.9 0.0.0.0 UG 0 0 0 eth0

and Host:

169.254.1.8 0.0.0.0 255.255.255.252 U 0 0 0 tmpGP7lkQ
