IMHO py-salt works as expected and as before. If you wish to apply FIB to packets belonging to the connections originating from the host, you should either start service with setfib(1) or use appropriate firewall rules to assist this. With PF(4) it could be route-to or rtable options, see pf.conf(5) Best regards, --=20 Marek Zarychta --rwEMma7ioTxnRzrJ Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEMOqvKm6wKvS1/ZeCdZ/s//1SjSwFAlnmWkUACgkQdZ/s//1S jSz+BwgAq9NysO7AjCU7RfyM+53L6/tYOCdV27iRsAGpFHg8A7NsbN4K7eU7TGic Gl9R6o5mTH9eyhJFLT0M5rnJGI75LLpXA7zUbLPfIqUsZT55OLIH65R/XB5bAzc7 5uaBkI3BrpMTesxknKWP0SoRzA+eGyXwIM+RJDvMGhrdvF9GSEy7hkTLW48s/+wV 8DjGvayy66DXhdKAKoZTCrtlZ+D03gug22+YUo1e39VxjGC/l5BfRMB3oN3z57ep spbGwJ52wJM/qrEmcQXPNo6E2s2ehLDB1as++4kluJbWvutuJocyBkwTHLDqzXey OhIYHrEtwyEnc81hGhmrYLuLLdLYbg== =bQyf -----END PGP SIGNATURE----- --rwEMma7ioTxnRzrJ--
