Your access-map is doing exactly what you told it to do. The 2nd entry matches all traffic to or from RFC1918 address space (including your vlan110!) and drops it. The first thing you need to do is figure out exactly what you want your access-map to do. Here's what I think you want: Permit traffic between your (RFC1918) subnet and internet-routable space (...

Assuming you want use VLAN 3 & VLAN 4 as your LAN network and want to configure pat natting for internet access, and assuming VLAN 1 is used for DMZ network for hosting an application which needs static NAT. Configuration of subinterface in router. For example in router subinterface configuration: Int g0/0.3 Encapsulation dot1Q 3 Ip address 192.168.2.1 ...

The Fortigate requires routes to the networks behind the SG 350. (Make sure routing has been activated on the 350, but I think it's by default.) Since the 350 doesn't seem to support any routing protocol you'll need to set up static routes on the Fortigate. In the GUI, static routes are in Network -> Static Routes. If you're not using those addresses ...

Private VLAN is a feature that prevent hosts within a single VLAN to communicate with each others. VLAN separate different networks. A site may consists of thousands computers, belonging to dozens of business unit or department, segregated by different VLANs. One VLAN for the accounting department, one for human ressources, one for IT, etc... Each VLAN ...

The -e flag doesn't work this way. When you write tcpdump .... -e vlan it doesn't mean "show vlan tag if available". It means "show link-level header" and "show only packets that match expression vlan". The flag -e does not take an argument! So the correct command for capturing everything is sudo tcpdump -vvv -i bond0 -U -l -n -...

Options 2 seems to be pratical and optimized Configure switch virtual Interface (SVI) in layer3 switch with VLAN 10, VLAN 20 ,VLAN 30, and configure intervlan routing "ip routing " to ensure communication between vlans VLAN 10 ,VLAN 20 ,VLAN 30 further connect layer 2 switch layer3 switch with interface trunk allowing all vlan to pass from link ...

The least-significant bits of the Bridge Priority are the ones repurposed for the extended system ID. Therefore, you can configure bridge priority to 32768, but you can't actually make it 32769! The precision is no longer increments of 1 but in fact the increments are 4096. Here's an old post on this topic with some graphics that may help: Spanning tree ...

The problem is that all the interfaces in slot 2 (G2/1-2 and F2/3-2) of the router are switch interfaces, and you are trying to use them as router interfaces, but that will not work. What you need to do for those interfaces is to create SVIs for the various VLANs, then assign the switch interfaces to specific VLANs as access interfaces or as trunk interfaces....

VLANs are logicall segmentation of network. If group of device belong to same single vlan means they should be in same subnet to ensure communication within this vlan by default. By default devices in same vlan communicates. If your network is connected to multiple different networks borders by layer3 devices in this scenario you can use same vlan with same ...

If your using fortigate firewall as core or perimeter devices and Cisco SG300 as distribution switch in your setup then you can accomplish this task by creating sub interface on fortigate firewall Configure SG300 switch to Fortigate firewall with trunk link allowing all vlans And configuration public ip of isp on outside interface of fortigate and configure ...

In case if you are using Cisco3850 or any other layer3 switch You can create svi in layer3 switch and connect firewall inside interfĂ ce(LAN) to layer3 switch (no-switchport interface ) Configure firewall inside interface with ip address 192.168.68.2 and switch interface leave as it is For example Switch(config)# int f0/1 Switch(config)#no shutdown /*This ...

Think of a VLAN as a virtual switch. Devices on different VLANs (virtual switches) share no common (data link layer) network, so they cannot communicate directly. A router connects different networks with each other, so attaching a router in between both VLANs and configuring the routing enables nodes to talk to each other across those VLANs. Configuring the ...

By default, different VLANs won't communicate with each other. You can make them communicate by inter-VLAN routing. For this requirement, you require one router and one switch. Instead of this, you can create layer 2 same vlans in switch and allocate both printers to the same vlan. In the switch, configure both ports on vlan 1 so that both printers can talk.....
