This is a cryptographically signed message in MIME format. --------------msF3182803C47209B2D56F5ABF Content-Type: text/plain; charset=koi8-r Content-Transfer-Encoding: 7bit Hi ! Are there any ways to limit such situation: We've got some clients physically connected to !stupid! ethernet hub ( I mean no VLAN, etc.). The links to them are PPP, not real, but limited by routing options, firewall. The problem is that some client can configure his interface with IP address from another client (making him good amount of traffic). Can we limit this situation by providing access and ability to work for some IP address only if it has predefined MAC address ? Thanks, Alex N. Zhuravlev. --------------msF3182803C47209B2D56F5ABF Content-Type: application/x-pkcs7-signature; name="smime.p7s" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="smime.p7s" Content-Description: S/MIME Cryptographic Signature MIIHzAYJKoZIhvcNAQcCoIIHvTCCB7kCAQExCzAJBgUrDgMCGgUAMAsGCSqGSIb3DQEHAaCC BZ8wggJuMIIB16ADAgECAgMEBK4wDQYJKoZIhvcNAQEEBQAwgZIxCzAJBgNVBAYTAlpBMRUw EwYDVQQIEwxXZXN0ZXJuIENhcGUxEjAQBgNVBAcTCUNhcGUgVG93bjEPMA0GA1UEChMGVGhh d3RlMR0wGwYDVQQLExRDZXJ0aWZpY2F0ZSBTZXJ2aWNlczEoMCYGA1UEAxMfUGVyc29uYWwg RnJlZW1haWwgUlNBIDIwMDAuOC4zMDAeFw0wMTAxMjIwNTMwMjJaFw0wMjAxMjIwNTMwMjJa MDwxHzAdBgNVBAMTFlRoYXd0ZSBGcmVlbWFpbCBNZW1iZXIxGTAXBgkqhkiG9w0BCQEWCmFs eEBzY24ucnUwgZ8wDQYJKoZIhvcNAQEBBQADgY0AMIGJAoGBAL6xOQ+P7j3NLmm36pC8vpZv lyKct+zmoLfBoEEreyfHlEw8e1rZgzL6Tj5rFGeFoZLmEhZUMRsXimFh321hKwcrwlS9bu0g yO30t4shvV7I59RnYY9OLSlZ3CN9k1s/xWTWhoYZKYP7Bg51t/9SLhNpH0R/45Wn3kCHFN63 rQhhAgMBAAGjJzAlMBUGA1UdEQQOMAyBCmFseEBzY24ucnUwDAYDVR0TAQH/BAIwADANBgkq hkiG9w0BAQQFAAOBgQByXaoPC3ReT0nne6u81fWiTrnhHgenOwlOwfIfe8GbGAnkewRl++4j NAC6qPO8IjUMy6Tx2g4IYs20xaBuds4w9X4maQLwZIcehpyJxytafxl/9nH6Am7OWSoKeVxg u+8IT7jTj/XJWA9vrE/x3mi4Jo5IPgWLLiv4ymuvMeG1hjCCAykwggKSoAMCAQICAQwwDQYJ KoZIhvcNAQEEBQAwgdExCzAJBgNVBAYTAlpBMRUwEwYDVQQIEwxXZXN0ZXJuIENhcGUxEjAQ BgNVBAcTCUNhcGUgVG93bjEaMBgGA1UEChMRVGhhd3RlIENvbnN1bHRpbmcxKDAmBgNVBAsT H0NlcnRpZmljYXRpb24gU2VydmljZXMgRGl2aXNpb24xJDAiBgNVBAMTG1RoYXd0ZSBQZXJz b25hbCBGcmVlbWFpbCBDQTErMCkGCSqGSIb3DQEJARYccGVyc29uYWwtZnJlZW1haWxAdGhh d3RlLmNvbTAeFw0wMDA4MzAwMDAwMDBaFw0wMjA4MjkyMzU5NTlaMIGSMQswCQYDVQQGEwJa QTEVMBMGA1UECBMMV2VzdGVybiBDYXBlMRIwEAYDVQQHEwlDYXBlIFRvd24xDzANBgNVBAoT BlRoYXd0ZTEdMBsGA1UECxMUQ2VydGlmaWNhdGUgU2VydmljZXMxKDAmBgNVBAMTH1BlcnNv bmFsIEZyZWVtYWlsIFJTQSAyMDAwLjguMzAwgZ8wDQYJKoZIhvcNAQEBBQADgY0AMIGJAoGB AN4zMqZjxwklRT7SbngnZ4HF2ogZgpcO40QpimM1Km1wPPrcrvfudG8wvDOQf/k0caCjbZjx w0+iZdsN+kvx1t1hpfmFzVWaNRqdknWoJ67Ycvm6AvbXsJHeHOmr4BgDqHxDQlBRh4M88Dm0 m1SKE4f/s5udSWYALQmJ7JRr6aFpAgMBAAGjTjBMMCkGA1UdEQQiMCCkHjAcMRowGAYDVQQD ExFQcml2YXRlTGFiZWwxLTI5NzASBgNVHRMBAf8ECDAGAQH/AgEAMAsGA1UdDwQEAwIBBjAN BgkqhkiG9w0BAQQFAAOBgQBzG28mZYv/FTRLWWKK7US+ScfoDbuPuQ1qJipihB+4h2N0HG23 zxpTkUvhzeY42e1Q9DpsNJKs5pKcbsEjAcIJp+9LrnLdBmf1UG8uWLi2C8FQV7XsHNfvF7bV iJu3ooga7TlbOX00/LaWGCVNavSdxcORL6mWuAU8Uvzd6WIDSDGCAfUwggHxAgEBMIGaMIGS MQswCQYDVQQGEwJaQTEVMBMGA1UECBMMV2VzdGVybiBDYXBlMRIwEAYDVQQHEwlDYXBlIFRv d24xDzANBgNVBAoTBlRoYXd0ZTEdMBsGA1UECxMUQ2VydGlmaWNhdGUgU2VydmljZXMxKDAm BgNVBAMTH1BlcnNvbmFsIEZyZWVtYWlsIFJTQSAyMDAwLjguMzACAwQErjAJBgUrDgMCGgUA oIGxMBgGCSqGSIb3DQEJAzELBgkqhkiG9w0BBwEwHAYJKoZIhvcNAQkFMQ8XDTAxMDUwNDA2 MzczNVowIwYJKoZIhvcNAQkEMRYEFLbKqLaKyIrSziS7S6w66Vw9Sb9vMFIGCSqGSIb3DQEJ DzFFMEMwCgYIKoZIhvcNAwcwDgYIKoZIhvcNAwICAgCAMAcGBSsOAwIHMA0GCCqGSIb3DQMC AgFAMA0GCCqGSIb3DQMCAgEoMA0GCSqGSIb3DQEBAQUABIGAbN3RWKnpCCxLhDeE1LUqe36+ YqAiHZ14rW/Og24MPRWoP3mLVbb2zzPk5fYEDXGI8x3EbuOS/8h3VQia5mcje6JR6FWpA+Wi 1ZHhQOJHdDbYekNILeR5fr4k0n2iHqPkoZeqLkF4b0s+DQnG/PLeiKvI+J9ZlqU9v/2tRANt tuU= --------------msF3182803C47209B2D56F5ABF-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
