A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Hi Here is a strange case. Anyone has an idea? Nesus5K is connected to Nexus2K with fex. Not sure Nexus2K port is broken. When PC is plugged into the port111/1/31 or 32 etc, PC NIC and switch port cannot be up. Finally we found all ports with command “switchport access vlan 2” have this problem. Other ports are able to be up once PC is plugged into ports with command “switchport access vlan 3”. All ports are no shutdown. and its configured in all there kind of ports is very simple, with one command "switchport access vlan x " Is this switch ports problem or vlan issue, or other issue? Thank you

Plus, we just tried unused ports in N2K. we still notice some ports with vlan2 are up, but they are being used.

My ISP is Comcast and I am assigned a range of 5 external IP addresses.

How can I determine which external IP address the SonicWALL VPN is using so that when I configure the VPN clients on Windows 10 computers I will put in the right external IP address?

The SonicWALL router is a TZ600.

I guys ,

I got a Cisco 547w router. Which does have a adsl connection.
For some reason. When I enter my wan ip in browser, it connects to my router page.
Is there any option to disable it ? I don’t need to access it with my wan ip. And it happens only inside the internal network.

From external it doesn’t work that way, because remote management is disabled. But for some reason when am inside the network I can access it with both private and public up.

Can u guys help how to disable the access through public ip?

Thank you

We have a Cisco 4500 connected to a Cisco Nexus 3172. There is a port channel setup as an access port to allow only VLAN 500 which is the internet VLAN. There is a management VLAN 2422 which is setup with netblock 10.5.0.0/24 which we are trying to access and we have no access to. Would we configure the port channel between Cisco 4500 and Cisco Nexus 3172 as a trunk port and allow VLAN 2422 to have management access to 10.5.0.0/24.

I have a client with a LAN, using a Cisco router, and then, in another area of the building I have a D-Link router set up as a wireless access point only (no wired connection to D-Link WAN port, DHCP off).

They want to add a guest network that is isolated from the private LAN.  If I enable the guest network on the D-Link it doesn't work, presumably because the Guest network is trying to go out through the WAN port directly, which isn't used because I've got it configured as an AP only.

If I add another router to handle Guest, in order to get the isolation I need from the company's private LAN, I've had to use 2 additional routers to get the isolation.  Is this the way to go, or is there something better that I can do?

Thanks.

We've just installed a new next-gen firewall and I need some assistance getting some communication between two of the interfaces.
It's a Watchguard T35 and we have our WAN on Eth0, LAN1 on Eth1, and LAN2 on Eth2.
Our WAN has a static IP, but we have /27 block of public IP's routed (at the ISP level) to our WAN for use by public facing servers.

I have that part of it working OK.  Servers connected to the LAN2 all have their static IP assignment and IP checks on the internet show the correct IPs.  This interface in the Watchguard is set as "Optional".

LAN1, is our private LAN and is set as "Trust".  Internet traffic and NAT/port forwarding is all working OK, but I cannot seem to get access to LAN2 from LAN1 devices.

I've created a firewall policy with "ANY" for the packet filtering and have set both 192.168.1.0/24 and 203.xx.xx.0/27 in both the To and From boxes.  The rule is set to allow and enabled.
But I cannot browse (using the IP or UNC name) or access any of the LAN2 resources from LAN1.  Nor can LAN2 access any of the LAN1 resources.

I'm new to Watchguard and thought I might ask here for any things I may have overlooked before lodging a support ticket with Watchguard support.

Dear Experts,

I have a set of fortigate firewall policies which I need to duplicate on a cisco router.

I have done most of the point A to point B.

The issue I have now is the NAT and there is an IP Pool, is there a guide on how I can translate the rules from firewall to cisco router?

Any help is appreciated.

Hey guys. Hope you might be able to help me out with this sort of...unique situation.

We have two facilities. I'm trying to set up some VLANs, but there's a catch: we have a fiber connection between the two buildings that is causing some problems. Let me give you an outline of our layout.

Internet comes in from ISP to a Cisco RVS4000 router/switch, plugged into WAN. Port one has a cable connecting to the main switch (Cisco) of Facility 1 (F1), which has a DHCP server running Windows Server 2008 (unfortunately. I have a new server to setup when I'm done with this project to fix that). Port three has a cat cable connected to a fiber converter going to single mode fiber running to Facility 2 (F2) about 10 miles away. (That connection is working flawlessly. I can plug into the main switch and be on the same IP range and domain as though it's just a long cat cable, because essentially it is.) At that facility, it's plugged into port 8 of a Netgear (I know) GS510TLP and running to a TP-Link (I know) T1600G-52PS. Port 2 on the Netgear is going to a TP-Link T2600G-28MPS for VoIP and port 3 is going to a T2600-28MPS for cameras.

I created some DHCP scopes and VLANs (VLAN 2 and 3) between all this mess and got it sort of working. By sort of, I mean I can plug into the switch at F1, and VLAN3 will give me a DHCP address from the server. VLAN2 will not. In order to do so, I had to use two other NICs in the DHCP server on the ranges (4.x and 5.x) I'm needing for those …

I have network diagram where we have replace the cisco switches with Aruba switches. We got the current cisco config so we can configure the new Aruba switches accordingly. Can someone help me to share a project plan template or something similar for the implementations. All the cabling will be in place on site and all the devices, spf modules will be there.

Hi Experts

I am looking for a router capable of delivering a DHCP range of  /19 or above, with DSL and ethernet WAN ports |(VDSL) for large applications.  On-board wifi is not required.  L7 firewall an advantage
Can you advise?  Many thanks in advance

What is the most reasonably priced captive portal router/ap or just Access Point?  The owner should be concerned about segmenting network from guest traffic when utilizing the captive portal feature.  I was thinking Sonicwall TZ series for traffic segmentation.  I'm not sure if the integrated wireless does captive portal feature or simply get a Ruckus for the wireless part but then the pricing quickly gets expensive.   Another more hooptie solution is a daisy chaining the primary and purchasing a cheap router/AP solution that again has the Captive Portal feature.  However, I'm not sure how much perform degradation for both the business and the guest segment would be.  Thoughts?

i have a Cisco ASA 5520 and 500MB internet/bandwidth line, the problem is the throughput on the FW is low and it throttles the bandwidth. Execs don't want me to upgrade now so i was wondering is there some kind of add on i can use  


ASA 5520
1: ASA5520, 512 MB RAM, CPU Pentium 4 Celeron 2000 MHz
2: Up to 2048MB RAM
3: Intel Celeron M Processor 450 2.0GHz
4: Cavium Nitrox Lite CN1010

This is using 2 VMware ESXi 6.5 hosts. There are 5 VMs per host. We are intend to have 1 vlan for management, 1 for backup segment, and 1 for the production segment. we intend to configure a NIC teaming on 2 physical network (vmnic0 & 1) port per host. Respective port-group for each vlan id were created. 101 for production, 121 for mgmt, and 122 for backup. All 3 port groups joined to the same vswitch0. Load-balancing mode is, Route based on IP hash.

This ESXi Hosts are connected to Cisco Catalyst 2960-48-port switch. The Ethernet channels were configured as follows,

int port-channel 1
  switchport trunk allowed vlan 101,121,122
  switchport mode trunk

int gigabitethernet1/15
  switchport trunk native vlan 101
  switchport trunk encap dot1q
  switchport trunk allowed vlan 101,121,122
  switchport mode trunk
  channel-group 1 mode on

int gigabitethernet1/16
  switchport trunk native vlan 101
  switchport trunk encap dot1q
  switchport trunk allowed vlan 101,121,122
  switchport mode trunk
  channel-group 1 mode on

Do these configurations work?

Thank in advance.

Dear Experts,

I turned on the router and hold the Ctrl + Break for PuTTy to send the break but it continues to load the IOS, is there any method other than physically removing the flash card to reset it?

Hi
We are expanding our office so will need to install an additional switch in another room c20 feet away from the comms.  At the same time we are looking at replacing our existing switches.  

Currently have a hp 2910al poe+ 48 port serving as GW for hosts.  It routes to the local firewall and thereafter out tot he web via router.  We run two vlans for data and voice.  
We also have two other switches connected via ports on the 2910al.  These are HPv170 and 3com 2952, these run only data, no voice.

Looking for recommendations for specs and types of switches.  We like HP but would use any other.  Ideally have some form of resiliency and HA in the comms room and the same with the other switch in the other room.

Would modules be any good?

We also have STP disabled for our voice to work.

Thanks

I'm working for project which has a total of 600 outlets(POE and non POE). I have 11 IDF distributed and 1 MDF. Server and storage will be at the MDF. These are my queries

1. I have outlets for Digital phone, Analogue phone, Wireless, CCTV, ACS, Data, IPTV,PTZ camera. Please let me know which all to be considered in POE and non-POE?
2. 4 core MM Backbone cabling is considered from MDF to each IDF. What all items to be considered in this fiber patching.
3. At the MDF side Fiber patch panel is considered. Fiber splicing and termination will be done at at one side of the panel. From the other side where the routing will go?
3. In each IDF separate POE and non-POE switch are considered. How will be the connection from this IDF POE/non-POE switch to the MDF?
4. Do I need to consider Media Converter for backbone cabling.
5. How to calculate the UPS/server/storage/router ? How much to be calculated for each rack


Please help me out to design this project as I am new to this field.

Thanks

Having a very strange issue whereby a few webpages do not display correctly on all computers in the office (including a mobile phone  - not on the company domain).
Two examples are speedtest and westin (see below)

speedtest.net page
westin.JPG
As such I am doubting the issue is related to any specific computer. Have spoken with the ISP (BT) and they say if they come and visit they will charge if it is not a BT related broadband issue. I am guessing the issue must be either on the router or somehow network related. I have tried local stuff like flushing the DNS, changing DNS to  8.8.8.8 etc but running out of ideas, apart from perhaps resetting the router. Apparently all was working fine up until a couple of days ago on this network. Any help/ideas would be appreciated.

Can't ftp & sftp to external ftp server, want to check which parts block the port connection. How can I simply check it? How can I check it at router, internal firewall, internal proxy?

We are a serviced office and have freely just passed broadband between all the tenants.
Since one of the tenants are taking a lot of the bandwidth we now need to apply limits to the pipe.
I’ve checked with out switch and we can only limit upload.
Please can somebody suggest the best way to do this? We can get new hardware if required. But not sure if this is usually achieved via switch or router and how it passes through for 30 separate tenants.
Thanks in advanced.

I am using Angular 6 and tried to hide sidenav bar in Login component. Once user logins, he can see navigation bar. (I have created fake backend for this project as this is just a prototype for my project.)

My problem is, I have to refresh to get sidenav bar on app component.

Can someone help me to solve this?

App.component.ts

export class AppComponent implements OnInit, OnDestroy {

  // Translate: Defining Supported Languages
  supportedLangs = [
    { active: false, display: 'EN', value: 'en' },
    { active: true, display: 'DE', value: 'de' },
  ];

  isOpen = false;
  loggedIn: boolean;
  username: string;
  mobileQuery: MediaQueryList;

  // defines if the sidenav should be opened. True in wide screen, false on mobile
  opened = true;
  // can be side or over, for resp wide screen and mobile
  over = 'side';

  watcher: Subscription;

  constructor(private media: ObservableMedia,
    private authenticationService: AuthenticationService,
    private router: Router,
    private sidebarService: SideBarService,
    private translate: TranslateService) {
    this.watcher = media.subscribe((change: MediaChange) => {
      // this language will be used as a fallback when a translation isn't found in the current language
      translate.setDefaultLang('en');
      translate.use('en');
      if (change.mqAlias === 'sm' || change.mqAlias === 'xs') {
        // mobile
        this.opened = false;
        this.over = 'over';
      } else {
        // wide screen

Two organizations (ORG1 and ORG2) have merged. Each of the two has branches connected by MPLS VPN. I have connected the two HQs by MPLS VPN through same MPLS Service Provider. Now I need to make branches of ORG2 to access information on ORG1. Is it possible to accomplish this without creating a straight VPN link from branch on ORG2 to ORG1?
