ipv6

I have problem to access some sites but not all, but I have internet connectivity normally. Example this site below cannot be accessed: https://www.linode.com/community/questions/2982/im-unable-to-run-telnet-on-localhost-25-how-do-i-fix-it-solved I get the following message in Mozilla; Hmm...

Configuring DNS caching server able to get all traffic without the firewall and with firewall only the IPV4 traffic is resolving, having some syntax issue with the config regarding the IPV6 (using FreeBSD 12.1) ipfw -q -f flush cmd="ipfw -q add" pif="em0" # interface name of NIC $cmd 00116...

Port net-mgmt/netbox is a nice tool widely used for IPAM and DECIM maintenance, so I tried to use it for maintenance purposes at work. I never got past the setup, since the example shown in FreeBSD's wiki (https://wiki.freebsd.org/Ports/net-mgmt/netbox) only covers a setup as vhost, which...

Hello All, i am trying to do NAT464 XLAT similar with below diagram (taken from RFC6877) I have 2 VM using FreeBSD 12.1 Release as CLAT and PLAT with the following Kernel Option : IPFIREWALL IPFIREWALL_VERBOSE IPFIREWALL_DEFAULT_TO_ACCEPT IPFIREWALL_NAT IPFIREWALL_NAT64 LIBALIAS on both VM i...

Hi all, I need to specify an IPv6 prefix in /etc/mail/access using CIDR notation and it doesn't seem to work (nor can I find it documented). My range is similar to: "2001:DB8:1111:2200::/56". My network doesn't fall on a 16 bit boundary so I can't just specify "2001:DB8:1111:22" as this is...

Hi I am using ipfw for firewalling on a FreeBSD 11 box. Unfortunately I cannot wrap my head around the fact that/why the following rule does not match when I initiate a TCP connection to 2a00:1450:4001:814::2003 (that is Google...): ipfw add 340 set 5 count dst-ip6 2a00:1450:4001:814::2003...

Hi! Maybe, I am just too silly or simply miss something. I try to configure IPv6 on my new testserver, FreeBSD 12 Release from bootonly-Image. rtsold_enable="YES" rtsold_flags="-aF" ipv6_activate_all_interfaces="YES" ifconfig_vtnet0_ipv6="inet6 2a02:4000:f:6c6::2 prefixlen 64"...

Hello, I have some jails on my FreeBSD host. They have IPv4 addresses on a cloned interface lo2 I created. None of the jails has an ip address on the external interface of the host. They only use the cloned interface lo2 and I configured my pf firewall so that the host acts as a router and does...

Hi All. My server's jail need outgoing internet connection for Let's encrypt OCSP Staple, but connect problem IPv6 only. Detail ifconfig wan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8000a<TXCSUM,VLAN_MTU,LINKSTATE> ether 00:1e:68:c4:e1:9e...

Hi all, When I start the jail, I get this message on my console. nd6_dad_timer: cancel DAD on epair1b because of ND6_IFF_IFDISABLED. Then the jail cannot use IPv6 until the base initiates connection to it (ie, the base pings the jail first). Otherwise, networking over IPv6 does not work Any...

I am currently running FreeBSD 12.0-RELEASE-p2, and I can't figure out how to create both IPV4 and IPV6 aliases for a loopback (lo1) interface using rc.conf on boot. Here is a snippet of my /etc/rc.conf: cloned_interfaces="lo1" ifconfig_lo1="inet 10.0.0.0 netmask 255.255.255.0"...

Hello all. I'm attempting to configure IPv6 Unique Local Addresses alongside the existing global addresses that are in use on my home network, as the global addresses are from a dynamic prefix delegation and could change from time to time. I want the ULAs to be handed out statefully using...

Hi forum. Until recently I ran pfSense on my gateway system for my home vDSL connection, but I decided to revert to plain FreeBSD and relearn how to configure everything manually. I've got it up and running with the typical setup of a private subnet (two in my case) NATed behind a single...

Hi, I have ipv6 from Hurricane Electric, Mikrotik GW, FreeBSD box on LAN. FreeBSD have ipv6 static address: 2001:470:1f15:86d::41/64 GW: 2001:470:1f15:86d::1 When trying to ping6 FreeBSD box from internet, Mikrotik sends: 13:49:20.783868 IP6 fe80::6e3b:6bff:feac:24b2 > ff02::1:ff00:41...

I am experiencing this odd issue when I restart one of my jails, which operates as the IPv6 router, does not respond to IPv6 packets, even though tcpdump reveals that it receives them. It isn't until it initiates a traffic with other hosts that it starts to respond. IPv4 works just fine. I have...

Hey guys :) I recently noticed that I couldn't access my website on my server. Some information: OS: FreeBSD 11.2-RELEASE-p4 pf: disabled ipv6 only?: YES ISP supports ipv6 and SLAAC?: YES Router: AVM Fritz!Box 7490 ping6 is enabled in my router settings (for the server) but fails when I use...

Hello FreeBSD Community, I cannot reach any global IPv6 address on my FreeBSD 11.2-RELEASE-p4 system hosted on Hetzner Infrastructure. This is my assigned IPv6 address: 2a01:4f8:1c1c:----::1/64 and this is the gateway: fe80::1 which (in my understanding of the handbook) translates into these...

While ipfw supplies me6, I need the list of IPv6 addresses for a specific interface to be used in an ipfw ruleset. "Screen scraping" ifconfig is one option, but having a firewall at the whim of the human-readable output of even ifconfig is concerning. Is there a better way with the "stock"...

Hi all, I cannot get rtadvd(8) to begin to generate new packets. I have setup rtadvd.conf as follows: epair7b:\ :addr="fd07:7882:b0e3:6d27::"\ :prefixlen#64\ :tc=default\ :rdns="2001:db8:53::1": I am expecting to see rtadvd send out broadcast packets to ff02::1, but nothing is...

I've been digging into IPv6 lately and have been successful in setting up a working dual-stack network. Altough I'm not pleased with my current setup; that is when it comes down to where the IPv6 address of my gateway box is assigned. I use the isc-dhclient to get a prefix delegation, and rtsold...
