We have only 5 usable static IPv4 IPs and many IPv6 static IPs. We want Multiple nodes/pc to be connected with Internet using nating/router because we have limited number of IPs. We would still want few nodes with static public IPv4 IPs. All nodes should have public IPv6 IPs.
Gateway <==> Router <==> Switch <==> Multiple Nodes
Router is directly connected with Gateway.
IPv4 with nating works perfectly in above case.
Gateway <==> Switch <==> Multiple Nodes
No router involved, switch directly connected with gateway.
IPv6 works perfectly
IPv4 also works if each node is assigned one static IP address.

Router
Gateway is directly connected with switch. Router (Both WAN & LAN) are connected with switch. In this case Internet works for few seconds and then it get's stuck.
I thought it would allow me to nat using router and simultaneously allow me to bind nodes with IPv6 IPs and few other nodes with IPv4 public IPs.
when I try to ping a host I get "Destination Host Unreachable"
How can I meet my requirements?
====UPDATE 1==== For testing we are assigning static Public IPs to all Linux nodes. Eventually we plan to use Nating.
