I have 2 DCs at a customer that also run ISC-Kea-DHCP servers. To be able to provide DHCP-Leases I added virtual interfaces to the servers with IPs in each VLAN. In turn there also exist routes to the VLANs: # ip r default via 10.0.0.254 dev enp0s31f6 onlink 10.0.0.0/24 dev enp0s31f6 proto kernel scope link src 10.0.0.230 10.100.40.0/24 dev enp0s31f6.200 proto kernel scope link src

Hello everyone, I'm having problem with SR-IOV transparent VLAN. My host is Fedora 22 and my guest is: pfSense 2.3. The NIC is Intel 82576. I'm using pfSense Packet Capture to check the packet and find that inbound packet still have the vlan tag. The outbound packet seem fine because the router can receive DHCP discover packet from the guest and then send DHCP offer and ARP request

Hello guys, *The scenario:* Today we have a samba3 NT4 + openldap as database. This samba3 is in a physical machine with freebsd and the openldap is in a VM. I plan to install samba4 AD on a VM using debian and then as a member samba4 as fileserver. As a firewall we use pfsense and in it we have several vlans, where each vlan has its dhcp server configured to distribute public IPs. *Samba3

Hi, I followed the "Optimizing CentOS for gigabit firewall" posting and as some posters wrote pf is soo sooo ssooooo mutch faster, I was thinking to give it a try. But I'm not familier to BSD so I was looking for some tools and found "pfsense" http://www.pfsense.org/ "pfSense is a free, open source customized distribution of FreeBSD tailored for use as a

OK, strange request but I want to bridge three vlans under linux 2.4. Bridging works fine with two vlans, but is failing to route when I add the third vlan. Situation is clearly to have Lan, internet and DMZ vlans. The reason they are vlans is that I am using a Linksys WRT54GS and hence you effectively have a 5 port hub on the back which can be segregated into flexible vlan groups. I

Hi all How much does configuring a network with VLANs improve or effect quality ? Is there much reason to justify the configuration of VLANs ( I know networking, but not VLANs at all) Would it not be better to find high traffic users and determine why? Your Thoughts Thanks Barry

Does anyone have VLAN tagging working from within a guest on vmware-server? I'm running a centos 4.5 guest on a centos 5 host with vmware server 1.04and I've tried creating vlans using both the /etc/sysconfig/network-scripts method and just doing it from the cli via vconfig. Either way appears to work, the OS creates the vlans, but I think vmware's network adapter must be eating the

--- In english --- Hello! I am to implement a new architecture of the network in my company but I do not know right where to start ... need help! Currently 90% of my servers are virtual machines under Xen. I have many valid IP networks and all Hypervisors are configured in bridge mode, to simplify. We have 3 VMWare ESX Hypervisor also in bridge mode. Some networks are exclusive to certain

I only have some experience with OPNsense but maybe you can relate: - In my case it was always the certificate.? - I had to add the cert to the system certs using CLI. Adding them in the WebGUI was not enough. - Port 636 did not work for me, only 389 using STARTTLS Hope that helps... On 16. March 2020 at 08:13:50, Stefan G.

As the issue concerns both the -user (configuration) and -devel (OOPS), I''m sending this message to both lists. Some time ago I complained about two problems: - VLANs are not working on machines with 100 Mbit cards - I get a kernel Oops (sometimes panic) when I try to use bonding and VLANs with Xen The root of the issue is the same in both cases: VLAN interfaces must *not* be

I have a question about bridges, vlans and switches. We had been using a bridge to provide filtering between our student labs and the main network. All the filtering does is check that a known IP matches a known MAC address, this stops students plugging in laptops and stealing an IP address. (And yes, we know about the MAC spoofing issues too) The connection was nice and simple,

I think it should be sufficient to do as following: - create and test the vlans as normal (i think you already did this) - try to create the bridge as follows (for the first try without starting xend): # network-bridge start netdev=vlan100 bridge=xenbr0 at least this was working on my debian testing installation but i have a problem now with incorrect tcp checksums in dom0 or domU. See my

My actual scenario is: -Hundreds PCs in a internal network (fixed IP), divided in +- 6 different subnets -A +- 6 customers with leased lines -A Cisco Catalyst 4006 connecting groups of PCs to corresponding customers (imagine a Call Center company) -Works fine. The problem: Frequently, it''s necessary to migrate dozens PCs from a customer to another. You know, change all IPs and

Hi all. What is the canonical way of getting xen to fully work with 802.1q (vlans) ? After (re)searching i found many ways but so far none is working. platform is gentoo (x86/32) and netwerk card a tg3. xen is v3. my config is as follows ... eth0 is simply up (with no ip) and i created several eth0.x interfaces corresponding to several vlans. eth0.10 is de ''default'' vlan

Hi, I'm using Vlans in my network as a way of preventing pier to pier communication - I only want nodes in the network to talk to the gateway (a linux box). I have successfully set up lots of sub interfaces using the vconfig too, one for each vlan. What I would like to be able to do is remove the ip address from each of these subinterfaces eth0.x and bridge them to eth0. I have successfully

Since virtio does not provide it's own ndo_features_check handler, TSO, and now checksum offload, are disabled for stacked vlans. Re-enable the support and let the host take care of it. This restores/improves Guest-to-Guest performance over Q-in-Q vlans. CC: "Michael S. Tsirkin" <mst at redhat.com> CC: Jason Wang <jasowang at redhat.com> CC: virtualization at
