vxlan with IPv6 underlay ?

Hi,

Is IPv6 underlay fully supported with FreebBSD ? I have created the a tunnel and associated an Ipv6 address to each side. I'm able to ping between each devicesl. But when I want to curl from the remote side it timeout. Locally on the remote side it is OK. Is this expected ? Should I rather create a bridge with vxlan as a member and bind nginx to it ?

```
$ ifconfig vxlan0 create vxlanid 108 vxlanlocal AAAA:BBBB:110b:102::100 vxlanremote AAAA:BBBB:110b:102::12
$ ifconfig vxlan0
vxlan0: flags=1008843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,LOWER_UP> metric 0 mtu 1430
options=80020<JUMBO_MTU,LINKSTATE>
ether 58:9c:fc:10:ff:eb
groups: vxlan
vxlan vni 108 local [AAAA:BBBB:102::100]:4789 remote [AAAA:BBBB:110b:102::12]:4789
media: Ethernet autoselect (autoselect <full-duplex>)
status: active nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
$ ifconfig vxlan0 inet6 AAAA:BBBB:110b:300::1/64
````

Ping from remote is ok:
```
ifconfig vxlan0
vxlan0: flags=1008843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,LOWER_UP> metric 0 mtu 1430
options=680323<RXCSUM,TXCSUM,JUMBO_MTU,TSO4,TSO6,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6>

$ ping6 AAAA:BBBB:110b:300::1

```

But when I run `curl -6 -v 'http://[AAAA:BBBB:110b:300::1]'` it timeout.
