This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --Iidg6rfuOs7nlt8IK7TTF2HXJjvmdo0pF Content-Type: multipart/mixed; boundary="4oV5xwkaXgG4blpXGNTNPKfHNSoucrnFR"; protected-headers="v1" From: George Mitchell <george+freebsd@m5p.com> To: freebsd-hackers@FreeBSD.org Message-ID: <72393abb-f966-c7ca-de1d-b0650bdf98dd@m5p.com> Subject: Best practices: changing ISP --4oV5xwkaXgG4blpXGNTNPKfHNSoucrnFR Content-Type: text/plain; charset=utf-8 Content-Language: en-US Content-Transfer-Encoding: quoted-printable So for a while I'll have service from two ISPs, and hopefully anyone who connects to my old external address will get a response from that address, and anyone connects to the new address will get a response from there. Internally, my gateway is a FreeBSD box using "pf" with NAT in the kernel, and my old ISP on one ethernet interface and the new ISP on another one. Has anyone written up a cheat sheet somewhere that I can review? What are the gotchas I'm going to run into? To begin with, I've set all my DNS TTLs to 300 to discourage people from caching the old address for too long. Thanks for any pointers. -- George --4oV5xwkaXgG4blpXGNTNPKfHNSoucrnFR-- --Iidg6rfuOs7nlt8IK7TTF2HXJjvmdo0pF Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEENdM4ZHktsJW5kKZXwRES3m+p4fkFAlnNzfkACgkQwRES3m+p 4flkFw/+KYuXjs3AW3EH8LRMqz2n90RaB2uTWftgYlPpnTHHs077piPv+PRfI+9e 1EuLA6PmSzXKcTnElBgW1b1u+2VMYu1CF0EDjT4prFfarn0mgcAxHFYx+coB0wME ADYhS7H9z/cJ2Q4ergPBVRaP1SHwQreFkR8kOkUX0aKVMnysckl4UN0y7YKb0kCj +/ZsPfU30H7UqpNiSwOhrgxYzga6dYXHsNllmu2R7oHvIZ2L2XK+yhsgJ49qn/Ca RbMhehoWdCDWotm76DGs5bqK7UzyEXxjkvs1/5y2xud7jEWSXijdIyEsy9Wx9oay nnE/QP7qVq32f6lk2iIbc3m+fZXg9cSFW12BiWxtCmsqzLRfHk+MFpMRu3rkbawX gMIBGb1OsvxExPhOkeuLm4AdUGov5RtSE5x8nXCUdcFGbqxTJtsebc4YuOXhvTQZ 0b9GBzoIZjvpi91DQ8gP9hheaLC9ERTFj23GohIfRhhSSEn2I6V4gaXb2FRLTn84 SbfX9GgvsO7rffMIIUyatC9X39FdyCIUG+ix8uZyqJUdXGIJqJTWd5RV68EMMvDD GunSsb/P87dkJjYwdSn/NKqDMjIMCqCYRknvZQ+jku3HqxC5tTH4j4FNDQGutII5 kfmf/VktRGt/uDMzF5gPYC8e7dhWllM3/P7PQ1pX+cm/rOMN/m0= =80mA -----END PGP SIGNATURE----- --Iidg6rfuOs7nlt8IK7TTF2HXJjvmdo0pF--
