Hi there! Does anyone know how to configure a static route or add a default gateway in lxc or kvm? Normally in a linux machine I would do that in /etc/network/interfaces.d/<interface> with nano and restart networking service, but the directory's empty

Also tried "ip route add" and "route add default gw" but got errors operation not permitted or unknown error -122

for the default route there's a property nics.*.gateways

dbrooke: I keep getting "Static gateways must be IPv4 addresses" if I try that

are you using host names?

No, just IPv4 and IPv6 adresses

I think it only takes IPv4

You may be able to use the /native route tool to add a route.

I just checked my definitions and I'm only specifying the IPv4 gateway in the JSON - the IPv6 gateway is picked up from the router advertisement (via rdnssd on linux)

Don't you have to set the promiscuous permission on the zone before it can do arbitrary IP address things?

sorry i mean that for the IPv6 DNS advertisement you need rdnssd

i.e. in the nics block,

"allow_dhcp_spoofing": true,

"allow_ip_spoofing": true,

"allow_mac_spoofing": true,

"allow_restricted_traffic": true,

one or more of those

allow_ip_spoofing is only necessary for kvm/bhyve, not for native zones

(for addrconf)

The global zone picked up the IPv6 gateway from router advertisements as well. I have made several virtual lx/kvm instances with static IPv6-addresses(allowed ip spoofing of course), but I cannot use them without a static IPv6 gateway and it does not get assigned automatically by the global zone like native zones

Can not assign IPv6 gateway or configure a default route manually in the lxc or kvm instance either

TheTim0Nat0r: does your kvm guest use privacy extensions?

I'm using SLAAC exclusively

and with the exception of the ip spoofing bug for kvm/bhyve, that works reliable

nbjoerg: Just ip spoofing, nothing else. I am using SLAAC as well and that works like a charm. But I can not contact anything through IPV6 with a static non-EUI64 IPv6 address(so without SLAAC), because there's no static IPv6 gateway assigned.

SmartOS does not provide functionality to provide a static IPv6-gateway(There's an old ticket ) and it seems like the virtual instances also do not allow us to modify this with ip or route or in /etc/network/interfaces.d in case of linux

my debian bhyve HVMs with static IPs and a static IPv4 gw do pick up the IPv6 gw from router advertisement so I'm not sure why that's not happening for you

dbrooke: Okay, so if I understood well : your debian has both static IPv4 and static non-EUI64 IPv6(without SLAAC) and picked up the IPv6 gateway on its own?

here's one my (anonymised) nics definitions stuff.dbrooke.me.uk/sp-B3Sif2.zzz

and it has default via fe80::db:f4ff:febd:fd00 dev net0 proto ra metric 1024 expires 1760sec pref medium

Hmm, I see. Will continue my troubleshooting journey in that case.

for completeness, that's bhyve and "image_uuid": "6ae6054a-95f7-4f8e-a3f7-88d1d22301bf" and I'm not aware of configuring or installing anything in order to make the gw assignment work
