    This problem has resolved. TCP conection from F5 to internal over 64k connection, so a new tcp session is started with the same ports  => tcp connection reset. Need SNAT with other self ip connection to internal.

I tried create 2 VS diffirent are VS_IPv6_1  and VS_IPv6_2 with same pool P_p6435 but VS_IPv6_1 working and VS_IPv6_2 not work with message ERR_CONNECTION_REFUSED. I don't understand where the problem lies

ltm virtual VS_IPv6_1 {
destination xxxx:xxxx:xxx::77.https
ip-protocol tcp
pool P_p6435
profiles {
fastL4 { }
}
translate-address enabled
translate-port enabled
vs-index 1160
}

ltm virtual VS_IPV6_2 {
destination xxxx:xxxx:xxx::11.https
ip-protocol tcp
pool P_p6435
profiles {
fastL4 { }
}
translate-address enabled
translate-port enabled
vs-index 808
