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,

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

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

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 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

OK, thanks again for all your help. I have resolved this, finally. The problem was that I configured VLAN 48 as the native VLAN on the trunk port.That was a mistake as apparently the native VLAN is the one where Cisco does not bother to tag packets. For now I set the native VLAN to VLAN 1 and that works. Cheers, Boris. On Sun, Jan 25, 2015 at 7:13 PM, Boris Epstein <borepstein at

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

hi, I have to configure Xen server and DomU''s which should be able to talk to different vlans - depending on services put on DomU''s. I would like to enslave 2 NICs via bond interface. Both NICs are on trunk ports which are configured in the same way, the same native vlan. I don''t know, if I have to add vlans tagging to eth* interfaces then enslave tagged eth*

Hi, I have a situation where router has to see hosts  in multiple vlans with the same IP address The test scenario is : --------------------- |  eth0 |     br0   | &lt;-------&gt; eth1.25 | eth1.26 | eth1.27 --------------------- eth0 = Internet br0 = Lan 192.168.100.1/24 host 1= 192.168.100.11/24 eth1.25 host 2= 192.168.100.12/24 eth1.26 I need br0 to see all hosts in all vlans

Hi All, I'm having some problems getting postfix to relay mail. I'd appreciate any tips. Perhaps there are some settings which I may have missed, somewhere. The postfix mail server is on VLAN 250 (192.168.250.0) whilst I have several other users on other VLANs (e.g. 91, 92, 93, etc... 192.168.91.0, 192.168.92.0, 192.168.93.0, etc...). So, if I had a PC sitting on VLAN 91 with IP
