If you are dumping the rl0 interface then my suspicion is that the subnet on 205.x.x.1 is wrong: 205.x.x.193 is not the same subnet as 205.x.x.1/25 so 205.x.x.1 should not be doing ARP requests for it, it should be accessing it via a gateway (router). --=20 As a computing professional, I believe it would be unethical for me to advise, recommend, or support the use (save possibly for personal amusement) of any product that is or depends on any Microsoft product. --vOmOzSkFvhd7u8Ms Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.4 (FreeBSD) iD8DBQFHIOl4/opHv/APuIcRAu5TAKCgjLDItH5O6Ci0SS8B5tw2EgnZYgCeO5dl T4kEe6Gt6QuB5boZzRiafxU= =iEWV -----END PGP SIGNATURE----- --vOmOzSkFvhd7u8Ms--
