From 9207897983a3bfafa0ec3e436c1ad67790f09f06 Mon Sep 17 00:00:00 2001 From: Christian Poessinger Date: Tue, 19 Jan 2021 21:01:20 +0100 Subject: nat: T2947: add many-many translation Support a 1:1 or 1:n prefix translation. The following configuration will NAT source addresses from the 10.2.0.0/16 range to an address from 192.0.2.0/29. For this feature to work a Linux Kernel 5.8 or higher is required! vyos@vyos# show nat source { rule 100 { outbound-interface eth1 source { address 10.2.0.0/16 } translation { address 192.0.2.0/29 } } } This results in the nftables configuration: chain POSTROUTING { type nat hook postrouting priority srcnat; policy accept; oifname "eth1" counter packets 0 bytes 0 snat ip prefix to ip saddr map { 10.2.0.0/16 : 192.0.2.0/29 } comment "SRC-NAT-100" } --- src/tests/test_template.py | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) (limited to 'src/tests') diff --git a/src/tests/test_template.py b/src/tests/test_template.py index 544755692..7800d007f 100644 --- a/src/tests/test_template.py +++ b/src/tests/test_template.py @@ -93,3 +93,22 @@ class TestVyOSTemplate(TestCase): self.assertEqual(vyos.template.dec_ip('2001:db8::b/64', '10'), '2001:db8::1') self.assertEqual(vyos.template.dec_ip('2001:db8::f', '5'), '2001:db8::a') + def test_is_network(self): + self.assertFalse(vyos.template.is_ip_network('192.0.2.0')) + self.assertFalse(vyos.template.is_ip_network('192.0.2.1/24')) + self.assertTrue(vyos.template.is_ip_network('192.0.2.0/24')) + + self.assertFalse(vyos.template.is_ip_network('2001:db8::')) + self.assertFalse(vyos.template.is_ip_network('2001:db8::ffff')) + self.assertTrue(vyos.template.is_ip_network('2001:db8::/48')) + self.assertTrue(vyos.template.is_ip_network('2001:db8:1000::/64')) + + def test_is_network(self): + self.assertTrue(vyos.template.compare_netmask('10.0.0.0/8', '20.0.0.0/8')) + self.assertTrue(vyos.template.compare_netmask('10.0.0.0/16', '20.0.0.0/16')) + self.assertFalse(vyos.template.compare_netmask('10.0.0.0/8', '20.0.0.0/16')) + self.assertFalse(vyos.template.compare_netmask('10.0.0.1', '20.0.0.0/16')) + + self.assertTrue(vyos.template.compare_netmask('2001:db8:1000::/48', '2001:db8:2000::/48')) + self.assertTrue(vyos.template.compare_netmask('2001:db8:1000::/64', '2001:db8:2000::/64')) + self.assertFalse(vyos.template.compare_netmask('2001:db8:1000::/48', '2001:db8:2000::/64')) -- cgit v1.2.3
