Hi,
I encountered some issues when trying to set the gateway to a link-local IPv6 address in a filter and am wondering if there is a trick I am missing:
When assigning a link-local address (say fe80::4242%eno1) to `gw` in a filter using e.g.
gw = fe80::4242%eno1;
the config file parser complains about a unexpected "%". Of course, it doesn't work without the `%eno1` either ("Invalid gw address"), so is there other way to pass the intended interface?
Hi Unfortunately this does not work and i do not see any workarounds in existing code. Our IP address data type does not keep 'iface' in it, so link-local IPv6 addresses are a bit of problem. Also, setting gw (regular) in reality sets both gw and iface for a nexthop (gw is resolved and appropriate iface is found). It makes sense to add workaround for link-local addresses so that setting link-local gw is resolved in existing iface, so at least things like: ifname = "eno1"; gw = fe80::4242; or gw = gw; would work. -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
