I just recently purchased an SG300 10 port switch. After reading through many of the threads here, I was finally able to get the different VLANs to route properly. However, I'm having a unique issue that I'm not sure if it's related to the switch or not. I currently have 2 VLANs configured on the switch.ports 1-4 are native vlan 1 (192.168.1.X) ports 5-7 are VLAN 10 192.168.10.X (Trunk Port with VLAN 1 tagged and VLAN 10 untagged)I have a Hyper-V server connected to both of these networks. The VMs are running on both VLANs on port 5. I have the following problem:When I have a domain controller VM on VLAN 10, I notice that many of the DC communications failed. I took a network trace and noticed that many of the RPC port ranges were failing. I am able to ping all of the hosts on VLAN1 and vice versa. My question is as follows:Does this switch have some type of security option that blocks high range ports? I can't seem to find the menu option indicating that this is the case. I have already set-up a NETBIOS UDP proxy, but this hasn't worked much. I still have problems connecting to machines on this VLAN range.
We are experiencing bridge storms and network slow downs and we believe we have traced the issue down to users plugging a cat 5/6 cable between 2 ports on the wall both wired back to a SGE2010 switch.
So we did a test - we plugged a single short cat 6 cable between 2 ports on a SGE2010, our access switch. Suprisingly, even with STP enabled, the switch DID NOT block one of the ports and in a few minutes the ENTIRE NETWORK was down, as CDP, STP, and ARP traffic became a multi-gigabit storm throughout the network.
Why on earth does this switch not block a port that is obviosly looped?
Every other cisco switch since I started on 1900XL's did this in 1999.
I want to setup an home network with a wireless router and use multiple switches for wired connections through out my home. I currently have an Airport extreme hooked up to a cable modem and a leviton gateway hooked up to the Airport. The 2 computers connected to the Leviton are on a windows 7 homegroup and share fine, but won't share or discover any wireless device connected to Airport. My main goal is to have a wireless/wired network with all computers sharing information with each other. I want 2-3 wired switches/gateways with a min of 2 devices connected to each, connected to my wireless router whiich is connected to cable modem.
I want to block everyone from seeing each other on the LAN. So when someone goes to network neighborhood they can't see no one else on EXCEPT for the pritner or so. I want to do this using a Cisco 1841 router. How can I do this?
I have an rv180 and I'm trying to setup a custom service that contains both multiple disjoint ports (some UDP some TCP), as well as a TCP port range. This has lead me to a couple of questions.1) Is it even possible to have a single custom service with disjoint ports? Is it just going to be necessary to define multiple partial services for this?2) Is it possible to forward a range of ports? It's clear how to define a service with a port range, but the port forwarding table interface only allows me to select one LAN-side port for any service. Is there a secret notation that I need to do here that will just forward to the same LAN-side port as the WAN-side port---effectively one-to-one NAT forwarding, but just for the selected service?
I dont mean a website like facebook.com, but i want it to block an individual page,such as a profile page, yet still be able to access the rest of the site? Again i'm not after facebook settings etc, but i want to restrict access to certain webpages within Lan.
i just want to ask how can i block all proxy server websites in my router( any brand ) so that no one can access, like facebook i already block it in the router but they still access using proxy server website.
How do FPS's open UDP ports without needing to configure the router to forward them?I never have to forward ports from my router to my PC. Every game i have somehow manages to open the UDP ports it needs without me having to configure my router. Yet when i check to see if those ports are open (prior to starting the programs) they always come back as blocked or closed. Now I'm currently working on a UDP Internet program and need to know how to do the same thing - open ports on a router without having to make the customer configure their routers. I'm THINKING that other programs start with a TCP/IP connection on the desired port and that opens the UDP port. Is this the answer or is there another method used?
In my office we have concrete walls and very limited wiring. The way it is set up is we have a Verizon DSL Modem that comes in then I have a router with it that splits the signal to 4 other routers that each split the signal 2 to 3 more times. I have to use routers so that it assigns IP addresses.I bought a new D-Line N300 Wireless router with USB imput. I want to attach my Home Media Network Hard Drive Cloud edition to the 1st router (attached to the modem) and then share the data off that hard drive with everyone connected to the sub routers.
We have a single HP 2810 switch being used for an iSCSI SAN.We want to replace it with dual higher end switches.But we've got another SAN to also setup now - Dell Equallogic PS6010E - that has 10gb iSCSI SFP+ ports.Can the 4 x SFP+ uplink ports on the Dell PowerConnect PCT5548 or the HP 3800-48G-4SFP+ switch be used for just the 10gb iSCSI, while the other 48 handle the 1gb iSCSI?We were told the uplink ports don't have buffering, making them bad ports for iSCSI traffic and only useful as uplinks to another switch.We only need 8 x 10gb ports (4 for 2 servers, and 4 for the Equallogic SAN), so if the above would work, it would probably save us $10,000 from having to buy a separate 24 port dedicated 10gb switch to handle it.
I currently have 1 cat 5 jack at my tv/entertainment area and will be needing additional jacks to add gaming consoles,streaming video player and internet ready tv at the same location.The current jack installed at that location is coming from a D-Link 8 port Gigabit switch installed in a different room.The switch is at capacity,all ports are full,so no additional availability there.My question is how to expand port availability at the entertainment area.Is it possible to put another switch or hub at that connection?Would there be a conflict with cascading a switch from one to another? I have a 25 meg fiber optic incoming service,so there is plenty of speed and bandwith available to handle these componets.
At my company, we lease 3 static public IP addresses from 1 ISP. We want to have 3 separate networks that each use one of the IP addresses. Network 1 is the computer network, network 2 is the VOIP network, and network 3 is the security camera network. I am trying to determine the best way to do this. I have come up with 2 solutions in my head, but I'm not sure if they will work or not. I would like to get some input. Solution 1:Solution 1 looks something like this. Fiber box -> Router-> 3 switches. There would be one WAN input on the router, that would have a static route to 3 different LAN ports. For example, address 18.104.22.168 would be assigned to LAN port 1, 22.214.171.124 would be assigned to LAN port 2, and 126.96.36.199 would be assigned to LAN port 3 (by assigned, I mean have a static route to it). Is there some type of router that is capable of doing this? Solution 2:Solution 2 looks something like this. Fiber box -> Switch -> 3 Routers. The ethernet cable would run from the Fiber Box to a switch, and then 3 routers would be plugged into the switch. Each router would have the Static information configured in them. Would both of these methods work? If so, which would be the best way to go?
We are in the process of installing time clocks at some of our sites around the USA. Our security department has asked that the time clocks be completely isolated from the rest of the network. The time clocks will be administered by ADP via a centralized firewall utilizing NAT. We have multiple subnets available at each site. Let me give an example to calrify what I would like to do. Example: Site A has 10.168.19.0 /24 user subnet and is configured for VLAN1 using 10.168.19.1 on the router as the default gateway. I would like to use subnet 10.168.20.0 /24 for the time clocks, configure it for VLAN2 and use 10.168.20.1 as the router gateway address for VLAN2. This should allow me to NAT one of our additional public IP addresses to the 10.168.20.1 gateway address thus completely isolating the time clocks from the remainder of the network. Problem is I have not done this before so I'm a little confused about how to configure it in the Cisco 3750 switches.
I have a router connected to my computer for the many laptops and netbooks used in my home. My computer is down for a bit.I have an internet card, but no one else can use their laptops/ netbooks.Can I also connect my router to my laptop for multiple use in the household?
Adding ports to my Fairpoint provided Westell 7500 Rev D DLS modem router which has only 4 RJ45 ports. Bought a Linksys SE2500 gigabit smart switch but it doesn't assign IP or pass on router assigned IPs. Can't get ASSISTANCE from Fairpoint [successor to Verizon] configuring router or any advice on other ways to get more wired devices on LAN.For speed in backups I'd like 3 devices to be able to communicate at giabit speed Want to have an NAS and 2 Win7 Ultimate computers on smart switch, 3 other wired devices [WinXP, AT&T Cell tower, & DirectTV whole house SWM interface] and wireless on the router. 1. Are Fairpoint specs for DSL published so I could get another DSL modem router instead of the Westell or is it better to configure Westell as a router only and use a new to be acquired router with or without the existing or a new gigabit switch. I have a DI-624 from the pre-DSL Hughesnet satellite days.2. Are there less smart switches which would work better and let router assign the IPs?3. If this is too complex for me, can you recommend a remote access consultant to walk me through this for a fee?4. I'm 82, have been in computing since 1960, mainly in on-line end user environment mbut don't know the bridging, PPP PPoE differences, and implementation or configuration details of current hard and software except as a user.
Ok, so i never had problems with this before until i reformatted my computer. I have used a program called simple port forwarding and i've also manually added the port seeing if theres a difference, but every time i check my port which is 25565 for a minecraft server it says either failed or not open etc.. I checked netstat -an and it showed it was listening to my ip address and port 25565.
I'm going to move offices into a shared situation with 3 companies. Each company will want its own private network so there's no snooping between companies. I am planning on using VOIP for the phone system (Nextiva cloud based). Is it possible to set up the system so that each company has access to the VOIP system but yet remains sequestered in the their own network for everything else. I was hoping to do this with one data port at each workstation using Cisco SPA-303 phones. The way I understand this, is that the phone plugs in to the data port and you daisy chain the workstation off from each phone. Is this possible to do this while having the system I described? Another wrinkle is that I'd also like all the networks to be access shared printers.
Ok, my roomate is hogging the bandwidth on our shared router downloading junk. I'm not sure if he's using a torrent, but just in case he is here is my question:How do I turn off the ports for torrenting on my qwest pk5000 modem? Is there anything else I can do that would work as well?My friend reccommended I turn off every port after 9000 or something.
I have been trying to block access to Steam and Left 4 Dead 2 on a specific computer, using the correct listed ports and using the port forwarding section of the router (setting the access to deny) however they seem to still be able to access both steam and L4D2 on their computer.how I can still block the access?
We have a client that is running a PC on a internet over satellite. To avoid any unessecery traffic over the satellite link (data traffic is quite expensive), we've suggested to use a 5505, as we had one handy already.
So basically what we wanted was to block everything outgoing and everything ingoing, except for example port 22 (ssh).
But I'm struggling a bit, since this is my first cisco router to be configured.
My interfaces are as follows. Outside - DHCP Inside (port 1) - 192.168.1.1
I'm only running ipv4.
in ASDM I made a static NAT rule for port 22, being forwarded to 192.168.1.5 (the computer)
in Access rules I made under outside (incomming rules) source=any destination=outside service=ssh action=permit
But when I try to add further rules to block everything else, it takes the SSH on port 22 with it. How should I do this the easiest way?
I was configure IPSEC vpn on ASA5540 and i have problem with port blocked. I am unable to block server ports to remote users.See below configuration. I need to configure vpn filter list but don't know how to configure vpn filter list.
I have 3 xbox 360s in the house and im having nat trouble with them, i am currently using an actiontec pk5000, from centrylink. i need to know if there is a way to open all ports on this router or if i should get a router/switch that i can open the ports on and use dmz on the actiontec for the new router to make this work.
I looking to buy SGE 2010 swith, but I have some question:
1. Can I use 4 SFP ports and stack of two switches at the same time. 2. Is it possible to use for stacking ports other than 24, 48? 3. What is maximum possible number of ports to use for stacking (can I get more than 1Gb thruput).
