Why special route for 10.0.0.3? No, those routes are normal. They were all added to the routing table by FreeBSD. On the second line, the 903 is an expiration time for the route. I'm not sure why FreeBSD adds these temporary entries (too avoid having to do an ARP lookup?), but they are documented in the handbook. The 1st line is just a route for the subnet on the rl1 interface. The final is just another route for what is presumable the broadcast address for the rl1 network. =20 Nathan --S4drRqups3dkeHIl Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQFCEQE4O0ZIEthSfkkRAm3UAKDORt/UyqcWEl/2dDzljD7Bu7CZkgCfb2r2 8Potx84/DexMOw6TMcmAKX0= =XOim -----END PGP SIGNATURE----- --S4drRqups3dkeHIl--
