Routers / Switches :: Isolate 1841 Router Fast Ethernet Port?
Feb 4, 2011
I have a Cisco 1841 router with the followingSerial T1 connection Fastethernet 1 with network address 192.168.0.1 Fastethernet 2 with network address 220.127.116.11I want to isolate Fastethernet 2 so that it cannot access the internet or the 192.168.0.1 network. Only incoming request is available.
I have a cisco 1841 whose LAN interface is showing status as "Fastethernet 0/1 is up , line protocol is down" the duplex and speed settings in the Router are in Auto mode and the Router was working fine till now , when i changed the duplex settings to duplex full , speed 100 the ping replies comes back with 5-6 replies then the link dies again..
I have a Cisco 857 router which i used for Internet connection with RJ11 connectior (ADSL0 POTS) but now the ISP has changed the internet link with PPOE type and the ONT connection is RJ45 , Is there a possibility to configure one os the Fast Ethernet ports as WAN port for internet.
I have a home lab. I am trying to connect a 1710 to a 2610 with just using the fast ethernet ports. I understand that serial connections and t1 csu/dsu connections use clocking, etc. How can I configure FA ports to do the same AND be routable?
I recently got a new Toshiba laptop, which works perfectly. We already have an HP desktop PC as well as a Dell laptop, which are both connected to an Ethernet router. When I got my Toshiba, I couldn't connect to the router, whether from a new Internet cable, the cable the Dell uses, or the cable the HP uses (it works perfectly fine with Wifi). The next day I got up early and tried again, and it worked. The HP was turned on, and it connected. But then the Dell wouldn't. Over the next couple days, we realized the problem was that the router only allowed the first two computers that were connected to it to connect to the Internet, but not the third one. The router itself allows eight cables to be plugged into it at a time, so I don't see why it's only allowing two computers, whether laptop or desktop, to connect. Is there a possible solution to this?It's an 8-Port Workgroup Switch, Model EZXS88W.Also, our router DOES NOT support Wifi
We would like to setup a link to our DR site that is separate from our main network traffic. This link will be used by an EMC VNX SAN for replication traffic. The SAN will be plugged into a fiber port on a 3750 switch and going out from the same switch (going in as multimode, going out as single mode) into a patch panel that runs over to the DR site (about a mile away). At the DR site it will go from the fiber panel into another 3750 switch which ends up going back out of that switch into our DR SAN.
I'm wondering what the best way would be to configure the fiber ports to accomplish this. I'm affraid that the replication traffic will find it's way over through another route and congest our main network unless configured appropriately.
I am trying to open port 12000 on my sky dlink router, been trying for a few days now and i just can't nail it. When i log into router, it brings up the sky router page, any one ever setup port 12000 on the sky router page.
ISP Cable in Smart box. 4 cat 5 cables from various rooms in house to feed cable ready TV's and one from my computer room. Can I connect all cat 5's to switch that is connected to cable modem located in Smart box and connect Wireless Router to cat 5 in the computer room and expect router to work properly?
I am unable to isolate DMZ and LAN traffic with an SA520 running 18.104.22.168 firmware. I have the optional port configured as DMZ and DHCP server enabled. I tired leaving the firewall as default. Also tried creating firewall rules to deny traffic from LAN to DMZ and DMZ to LAN for any address and any service.I am still able to ping devices both from LAN to DMZ and DMZ to LAN. I am also able to see network resources in both directions.
I attached an Iomego Home Media network hard drive to my Linksys E3000 router (via ethernet cable). Before setting up the remote access on the Iomega, I forwarded the ports that it wanted (443 and 21) to the static IP of the Iomega. I checked to see that they were open using yougetsignal.com and they were both open. After setting up the remote access on the Iomega, the 443 port closed and I cant even get into the "manage storage device" page for the Iomega. Iomega uses TZo for the domain names. They tell me that the association is made between the name and my public IP address. My router is out of warranty since Sept, so Linksys wont give me the time of day. I contacted my ISP and while they block a couple of ports, 443 is not one of them.I've installed the latest firmware (1.0.04 - Build 6). Reset and rebooted numerous times, Port 443 remains closed.
My Belkin F7D4301 Router has the fastest wireless speed of maybe 2MBps but wired with a cat5e cable to my asus laptop of almost 7MBps. I have a one smart TV, one blue ray, one roku, and a nexus 7 using the 2.4 channel.
My Wireless 2.4 settings are channel 11, Extension channel 7, Wireless mode N (have tried with just g and b, g, and n modes), Bandwidth 20/40, Protected mode on, QOS off.
I've talked to Belkin tech support, they are the ones who had me set up my 2.4 channel this way but my wireless speeds stay just under 2MBps, they just want to keep sending me the same model Router because they think each of the new ones they send me is defective.
Am I doing something wrong or is 2MBps the best wireless speed I'm going to get?
I currently have 2 PCs that are directly connected to each other via a 1Gbs Cat6 connection.I don't currently have a 1Gbs router so what I am doing right now is unhooking this connection and reconnecting both machines to my router when I need internet access. I have ordered some USB Wi-Fi adapters so I can have both machines access the internet that way whilst still use FTP between them on the 1Gbs line.If I were to scrap that idea and get a 1Gbs hub, connect both PCs straight into that, and then also connect the hub to my 100mbits router, would the 2 computers be able to communicate with each other at 1Gbs and then talk to the router at 100mbits, or would the whole network run at 100mbits.I don't really want to have to shell out on a 1Gbs router as I don't need anything else on the network to run at that speed.
Is it possible to set up a WAN interface on a FastEthernet interface of a Cisco 877 Adsl Router ?Due to my ISP, i've to use an external VDSL modem and must connect it to my cisco 877 router (and leave it's adsl interface unused).But i don't know how to set up a wan port, other than the adsl interface itself (dialer0), on my cisco.
Is there a difference in an ethernet cable and an Ethernet networking cable? I have an Ethernet cable and a 6 port splitter I am trying to connect. I have 4 ports in the router that are in use. When I connect them to the splitter nothing s working.
I have a Huawei 523a Router at the moment and I'm trying to setup a IP camera.The Router doesnt allow port forwarding, so my question is can I add another Router onto the Huawei router to allow the second one to work my camera
I have 4 desktops cat5 to Dlink DIR 615 router. All work fine. Any wireless clients, laptop or netbooks, see the desktop computers for a while then disconnect somehow. All machines can see the Internet through the router at all times. The desktops disappear from the laptop/netbooks but the wireless machines can be seen from the desktop computers but clicking on them gets 'Access Denied' message after a wait.3 desktops = XP, 1 98SE. All laptop/netbooks = XP
I am having a heck of a time finding information on this. I have a 2620xm router that only has one Ethernet port on it. Is there an expansion I can get that allows me another Ethernet port. I have thus far assumed that all of the WIC cards won't allow me to attach to an Ethernet LAN.
I had a question regarding the Cisco 2811. I tried fitting an NM 2FE-2W card and the fast Ethernet interfaces of the module never get recognized. Is there a special command to enable it or isn't the module supported at all by the router. If not , is there a way to have the router possess more than the 2 Fast Ethernet interfaces it already has? Let me know if any more info is needed from my end.
Another question I have out of curiosity. Is it possible to make the controller T1 port of a VWIC 1MFT-T1 or a VWIC 2MFT-T1 act as a fast Ethernet.
We have a network in place. A week ago we switch to AT&T's UVerse and they replaced the Motorola modem with a Motorola NVG510 modem/router. There was a Netgear router behind the original Motorola but since we only needed 4 ports I pulled that out of the loop and used the Motorola. The three computers connected directly to the Motorola came right up. However, there was a switch with two computers connected to it and when the switch was connected niether of the computers connected to the switch would go to the internet. I took one of those off the switch and connected directly to the Motorola and immediately connected to the internet. Put it back through the switch and nothing.
I'm watching a video streamed from my laptop and the signal is constantly being dropped. I suspect the D-Link DES-105. I have another Ethernet switch on the system as well but it is a Gigabit unmanaged switch from D-Link and has worked well with video streams. I've removed the DES 105 from the circuit and videos play fine. Should I dump to DES-105 for another Gigabit switch? SOme say I have a bad cable somewhere but I have tested all and have not found a problem.
I have setup an Asus RT n16 with 3 computers that support gigabit ethernet and a media server on one floor. On the other floor I have set up a fast ethernet switch (connected to my asus router) which is connected to several fast ethernet enabled computers.
Would the fast ethernet devices slow down the entire gigabit networking to 100mbps connections on my floor - similar to how a wireless n network running at 300mpbs must slow down to 54mbps when a wireless g device is connected to it?
I'm using a Cisco 1812 to route traffic from a small location with 10 users.. Users are complaning about packet loss, and programs with live database connection is freezing..On the router i've checked one of the Fastethernet interfaces, and I can see that the input errors are increasing constantly.
