I have 2 IPv4 subnets which are connected to each other via an IPv6 network. For several reasons I don't want to go into here it's better for me to use NAT-PT at the two v4/v6 boundaries instead of creating a v4 tunnel over v6 network.
The result is that I can ping from one v4 host to another v4 host across the v6 network. I can also run UDP traffic across the v6 network, but not with TCP. Does anyone have any suggestion?
Thank you
