similar to: un/Tap IP Configuration

Hello list, Please don''t shoot me. I know I''m doing something with bonding that bonding wasn''t made for. I just want to give it a try. I want a simple mechanism to have a failover on a 24Mbit line to a 2Mbit line in case the 24Mbit line goes down. Between A and B there are two lines: a 24Mbit and a 2Mbit. I use two OpenVPN tunnels with tap devices: +-- tap0 (A)---

Hello, I already consulted related lists @freebsd.org [1,2] but I have remained unsuccessful to solve the following issue: VPN works for an internal IPv4 subnet, but I doesn't for an internal IPv6 subnet with ULAs. To be honest, I don't have any experience setting up a local IPv6; so I guess that I'm doing something wrong here. For those that know FreeBSD: The main aim is to connect

Here https://www.tinc-vpn.org/documentation/Example-configuration.html#Example-configuration you have: For Branch A BranchA would be configured like this: In /etc/tinc/company/tinc-up: # Real interface of internal network: # ifconfig eth0 10.1.54.1 netmask 255.255.0.0 ifconfig $INTERFACE 10.1.54.1 netmask 255.0.0.0 Is netmask 255.255.0.0 or 255.0.0.0 ? Thank you!

I have now got the tinc demons (on network OFFICES) on BranchB and BranchA talking to each other, see below for log from BranchB. For some trouble shouting issues relating to OsX see at the end of my e-mail. However, I have not yet achieved the network connectivity/routing that I would like. The aim is: BranchB is a laptop I would like to connect it (via tinc) to my office network, so that

Hi, I have some problems with my OpenVPN server in a Xen DomU. OpenVPN works fantastic but theres a problem connecting other DomUs on this server. I have the following iptable rule to forward the requests to the internet. iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j MASQUERADE This works fine. I can connect to other DomUs on the same server but they can''t answer the

I think it should work at least for TUN virtual interface as TUn works at IP level. This is a sample configuration. firewall1 lan = 172.16.1.11/19 (ALWAYS ACTIVE) - "Physical Network Interface" - system config as ifcfg-... 172.16.1.10/19 (VIP Keepalived Make active) - Active/Passive configuration with firewall2 firewall1 vpndr1

Hello, I successfully set up a tunnel with tinc using the tun interface. however I need a tap device, because I need to run the OLSR routing protocol on the tunnel and if I use the tun mode OLSR will just skip the interface. (It is a well known thing, I had this issue before also when using OpenVPN in the past). The problem is that I cannot make tinc use a tap device. I created the tap0

Hi everyone! I have the following requirement: I need to connect a set of Docker containers to a KVM. The containers shall be isolated in a way that they cannot communicate to each other without going through the KVM, which will act as router/firewall. For this, I thought about the following simple setup (as opposed to a more complex one involving a bridge with vlan_filtering and a seperate VLAN

I have a Debian 8 64-bit machine set up as a server and apt-got the tinc package. I configured tinc as a bridge and everything seems normal except that the tunnel does not forward multicast traffic. I used tcpdump to examine the br0, eth0 and tap interfaces. I could see multicast packets on both br0 and eth0, but there is no such packet present on the tap interface. I don't quite know why

I have succeeded in getting two tinc1.0pre3 hosts to connect, but I can't ping one from the other. I can ping the local tap interfaces. tcpdump shows that icmp echo requests are received by the other host, but no replies are sent. The two hosts are North and South. It is the same pinging North to South and South to North. The hosts are configured as follows: South: Debian 2.2

Hello, I am trying to run a virtual machine with qemu-kvm and libvirt as a user. In order to start the virtual machine I setup a tap device manually, add it to the bridge and activate it via ifconfig. But I cannot tell libvirt to not try to add the definded tap device to the bridge by itself. It always fails telling me it cannot add tap0 to br0. Thats the xml snippet for defining the network:

It is possible for tinc to made a persistent tun/tap or can I configure a persistent tun/tap by hand and tell to tinc to use that virtual interface device without starting up/shutting down tun/tap at every tincd start/stop ?

I encounter a problem about the network when using virt-manager to create and run a VM. when I want to establish a network bridge for the guest OS, I generally use two kinds of ways described as fellow : First method : create a bridge with the help of linux commad: brctl, or Second method : using

Hello, On KubeVirt, we are trying to pre-create a tap device, then instruct libvirt to consume it (via the type=ethernet , managed='no' attributes). It works as expected, **unless** when we create a multi-queue tap device. The difference when creating the tap device is that we set the multi-queue flag; libvirt throws the following error when consuming it: ``` LibvirtError(Code=38,

I have now got the tinc demons (on network OFFICES) on BranchB and BranchA talking to each other, and I have been able to access services (like AFP, Apple file sharing) between the two hosts (in both directions), but not beyond the local network connected to BanchA. I am unclear which routing can be provided by tinc and which routing would I have to add manually. The aim is: BranchB is a
