Ok, I have a solution for you on the UDP source IP issue.
In the network namespace we need to enable the following kernel settings (these need to persist reboot too!):
echo 1 > /proc/sys/net/ipv4/ip_forward
echo 1 >/proc/sys/net/ipv4/vs/conntrack
Then when we add a member network with UDP we need to add an iptables masquerade rule:
iptables -t nat -A POSTROUTING -p udp -o eth2 -j MASQUERADE
where eth2 is the interface, inside the network namespace, that is connected to the member server subnet.
Don't forget to take into account the member subnet may be the same as the VIP subnet.
