Cisco Switching/Routing :: Using PIX 501 With Linksys Wireless Router
Oct 18, 2012
I have just moved to a community where Internet access is proved by a cable modem with a single connection. I am considering a purchase of a Linksys EA4500 or EA6500 wireless modem but already have an old PIX 501 security appliance from years back. Should I connect the cable modem to the PIX 501 0 port and then connect the Linksys wireless router to one of the other PIX 501 ports or should I just skip using the PIX 501? I don't know if using both devices will cause more conflict than benefit.

I work at a small company and have very limited experience with networking We have an ASA 5510 that connects out to our ISP. The inside interface is connected to a port on a Trendnet Switch (where all of our clients are connected as well)using 192.168.0.0/24 We also have a Linksys wireless router connected to one of the ports on the Trendnet in which it (wireless router) receives an IP via DHCP from the ASA. I know this isn't the best setup so I would like to connect the wireless router to one of the interfaces on the back of the ASA and have it able to communicate with the 192.168.0 network without any restrictions. Is this possible to setup? If so can it be done using the ASDM?

my trouble is I have a cisco 857w and I have never configured a wireless config for a cisco router before. Ok so i have had a go through the web interface (i know, last resort) and still no joy
Basically what im looking for is to have a visible (broadcast ssid) network with a password (WEP/WPA/WPA2, not picky) and it to be joined to the same vlan as the ethernet ports (VLAN 1).

I would like to ask for a cisco wireless router that supports captive portal. I notice that WAP321 supports this but what other additional units should be added in order to accomplish this. Client wants the user to authenticate first and also to see who logs in.

I am using BEFW11S4 router at my home. Most of the time it is working fine but sometimes its wireless network stops working–the green light also switches off. I recently upgraded the Firmware to version 1.52.03.

I would like to use the EA6500 in my network - but nor as primary router (or in fact routing at all). I would have thought, one could simply tell the device to use a particular gateway, but it does not seem to be easy. I have used many other home routers as combined switch/AP/USB-drive (latest a D-Link DIR-655), but the EA6500 seems very picky. The "easy" "Smart Wi-Fi" setup requires internet access through the WAN port - and that divides my home network, which then have two zones which cannot really "talk" to each other. Alternatively, I can reset the device and access it directly on the IP (initially 192.168.1.1). But then I can change only LAN and WLAN settings. Stuff like Guest Access, USB-devices etc. won't work. Do anybody have success with this device without using the WAN port and the DHCP server?

Is it possible to create a managed schedule to switch the wireless radio on/off? I want to set a start time and a stop time so that e.g. the wireless can be switched off during nighttime.
I had previously routers from both dlink and zyxel and they both had this feature.
I am sensitive to electromagnetic radiation and bought the EA4500 due to the 5 Ghz capability, - but then only to discover that the radio always has to stay on (at least as far as I have found out.

I have a problem with low throughput E3200 router. I have about 250 Mbps speed connection by Cisco EPC3925 cable modem. If I connect my computer directly to the cable modem, I can easily obtain the speed of downloading data from a fast servers about 200 Mbps and even more. When I'm connecting through E3200 I can get about 80-100 Mbps when downloading data from the same sources. I have tested this on few computers with different operating systems (Win7, Mac OS X) and there is no change. Between the cable modem and the E3200 router the cable link is @ 1Gbps. Also, between the computer and the router is a 1Gbps link. If i change router E3200 for cheaper and weaker model WRT320N then I can easily get about 200Mbps.I have the latest available soft in my router E3200 (1.0.03). I'm disappointed with low productivity, this router is not cheapest one

I have an ASA 5510, with Ethernet0 connected to Internet via a T1 line, Ethernet1 connected to LAN1, and Ethernet2 connected to LAN2. LAN1 & LAN2 are independant, but share the Internet connection, via the T1 line. On LAN2, I have another router that connects to the Internet, via a Comcast line. I wish to route some of the traffic on LAN2 (10.38.77.0) to the other Router, on LAN2 (10.38.77.12) (connected to the Comcast line). I have entered the following lines:
route inside2 10.11.0.0 255.255.0.0 10.38.77.12 1
route inside2 10.252.0.0 255.255.0.0 10.38.77.12 1
route inside2 172.22.6.0 255.255.255.0 10.38.77.12 1
I can trace the routes from the ASA 5510 (1st hop is to 10.38.77.12), but not from anything else on LAN2.

I have an environment of 3 X 3560G of which I have 1st switch-CORE(f0/10) connecting to the VPN router(CE) interface-f0/0. Remaining 2 Cisco 3560's(Access) are connected to Gi0/1 and Gi0/2 on the 1st switch-CORE via gi0/1 . On all three switches I have created multiple VLANs and assigned ports to these VLAN. The switch to switch connection is trunk allowing all VLANs created on all these 3 switches. Now the issue is how I am going to have all these VLANs routed through single interface on the routeri-e f0/0, as all these subnets will communicating to remote site over VPN. What should be default gateway on the 2 Access switches and the CORE switch, also what static route should be on router to reach all subnets(VLANs) created on these 3 switches.
I have read inter-VLAN routing i-e creating sub interfaces on router but dont want to proceed with that and looking for any other way to have my VLANs talk on all three switches and then are accessible to remote site ove VPN?

I have an 1811 with several subnets connected to it.I recently installed a 3750x plant and want to bring my interior routing back to it.
All the routing is handled by the 1811 via secondary interfaces on vlan1?
I have 192 ports, and subnets show up on almost all of them. None of the ports are assigned to any specific vlans. Most ports have several subnets on them.
What is the best approach to getting the 3750x to handle the routing?

We have small which I'm looking to implement and have built this on GNS3.
We have:
Router A in site 1
Router B in site 2
Router C in site 3
Router A and B are connection via a point to point 100M link and from Router C we have a 2 point to point one of which is 5Mpbs and going to Router A and Router B.
For Router C to reach Router A network it will go via Router B and these are 100M connection. When the link between Router A and B goes down. Router C should update and start using the 5m route.
For some reson, the routes are not updating. I have to do 'clea ip eigrp ne' for the routes to update and if I reload the routers all works well, it seems the problem is intermittent.

I’ve been trying a few days now to implement multicast routing on my home network in order to make airplay work between subnets. Specifically between an iphone and a hifi separated by different vlans. Failed, as I have no experience in multicast routing. we have a clean configuration and simple network which consists of two SVIs
Vlan 10: 192.168.1.0 255.255.255.0
Vlan 20: 192.168.2.0 255.255.255.0

I am having some issues with configuring static DNS on my e2000 router. When I configure the opendns addresses on static dns 1 and static dns 2 , all traffic, including traffic that should be internal to my network, gets routed to opendns. I tried to switch to staic setting and then putting in opendns into the dns server addresses but when you hit save it also sets the address and sends it along with DHCP to each pc.

I was assigned a static block over PPPoE from the ISP. I can connect to the internet using the gateway address but I need to route the other static IPs to my servers. I might say that I accomplished it on a couple of older routers - E1200 & WRT120N, but I cannot get it to work on my new EA3500. I have 5 usable IPs plus the gateway IP that is assigned with the PPPoE connection on the WAN port.

I just upgraded my in-laws network from a WRT54G to a E4200. It's working but I'm getting issues with the 5Ghz end. I've got both SSIDs using different names.. so its clear which I'm connecting to. I have a macbook pro which has N support and can see the 5GHz SSID.The issue I get is that when I connect to the 5Ghz SSID, the laptop cannot ping or connect to LAN clients on the 2.4GHz end. This includes SMB shares, a couple of devices with web interfaces and one machine running a VNC server. There is also issues with Internet access.. but only sometimes.
Say I have two terminals open.. one pinging Google and the other pinging one of the 2.4Ghz clients. If I connect to the 2.4Ghz SSID, I get both pings working fine. If I switch to the 5GHz SSID, the macbook gets its IP address but then the Google ping will work but the internal ping just keeps failing. The Internet issue.. looking back on the above example.. sometimes the Google ping will also fail. The mac also sometimes indicates that there is no Internet connection behind the wireless connection when this happens.
When I connect on the 5Ghz SSID, I get my LAN IP address from the router (ifconfig). I can also see the /etc / resolve.conf correctly populated on the macbook with thge gateway and DNS settings.For now, I'm just going to get them to only use the 2.4Ghz SSID and assume that a later release of the softeware will fix things.. it could be a compliance issue on the Apple/Cisco N support.

We are using a domain and Windows Server 2008 machine with DNS/DHCP setup and active to handle traffic on the network. The old router we had was a cheap (~$20) TrendNet that was configured (not by me) without issue to not only allow the server to handle IP's but also allow us to get in to the server remotely via Remote Desktop. My cut sheet says they had a "virtual server" setup.
Anyways, we now are running an E2500 and if I put in the external IP, Subnet, Gateway, and DNS for our internet provider and then disable DHCP on the router, we don't get internet access. I'm missing what configuration I need to get the server to handle all the traffic I guess. The server has DHCP enabled with the router IP address (192.168.1.1) set and the server address is (192.168.1.2). Like I said before it was working fine with our old router and none of the settings on the server have been changed so must be something with the new router.
Do I need to setup something in the advanced routing to get this working? Currently I have DHCP on automatic and DHCP server enabled just so we can get internet access. DHCP services on the server are still on as well. Can't get any access to the server from the outside via Remote Desktop like we could before.

This happens intermittantly. This results in most connections (but not all) being dropped. I will be unable to connect to web servers. My connection to videogame servers will drop. However, AIM will stay connected. These were done simultaneously. The same thing happens with my Cisco AE1200 and a D-Link 802.11g adapter I have. Disconnecting my adapter and reconnecting it solves the problem. I have tried doing a factory reset on the router and installing the latest firmware. It seems to happen more frequently when I am doing a lot of throughput (downloading a game on Steam, for instance) but other times it will happen when all I am doing is playing a game (like Tribes Ascend) which uses very little data. This is extremely frustrating. When I pay more than $150 for a piece of networking equipment, I expect it to last more than 3 years.

E3200 works great until I enable QoS. The device uses QoS and works find until reboot. If QoS is enabled and the device is rebooted, its stops routing from LAN side to Internet side. Administration-->Diagnostics allow me to ping/trace route to Internet sites and local LAN clients but cannot reach Internet from local LAN.
Windows networking icon indicates "No Internet access". I can ping other devices on local LAN.
Disabling QoS restores routing and you can re-enable QoS after that and all is well. Unfortunately, if there is a power failure when I', not there to disable/re-enable QoS afterward, other household members can't use the Internet till I get home.
Wondering if any other QoS users have observed the same problem.

I'm suffering from an annoying problem with my E4200 router. I have a DSL connection. I have my DSL modem in bridge mode and I have my router set up to sign into my ISP's PPPoE to avoid double-routing. This set up worked marvelously with my previous WRT54G and WRT610N routers.Now the E4200 signs me out of PPPoE every ten minutes or so. I have the connection setting on "Keep Alive" but it seems to be dropping the connection regularly. I took the router back and was given a replacement. The new router is doing the same exact thing and now I am beyond the 30 day return limit so I'm stuck with the E4200. I'm running the latest firmware 1.0.03
I reinstalled the WRT610N and the connection is steady but the WRT610N has its own problems (devices connected via wireless cannot see wired devices and vice-versa). I'd like my new router to actually work properly. I've ruled out errors on my end and given that two brand new units of the E4200 generated the same problem I tend to believe it is a design error.

I would like to upgrade the firmware on my SRW224G4 switch but I don't know which file I should be using. When I go to download firmware I see links for the following
"Cisco SRW224G4 24-port 10/100 + 4-port Gigabit Switch - WebView"
Which has firmware 1.2.3.0
"Cisco SRW224G4 24-port 10/100 + 4-port Gigabit Switch - WebView V1.0"
Which has firmware 1.2.2a
I'm not sure which firmware I should use, and the last thing I want is to brick this switc.
Below are the current firmware details

I have a problem with my switch. The model no. of the switch is as follows:
Linksys SRW2048 10/100/1000 48 Ports
Serial No: RJT00GC00395 GGR2906 MM
1. I am creating a home computer lab. I do have 3 servers HP ProLiant DL 385 G1. Two of them have 6 gigabit ports where as the third server has 2 gigabit ports.
2. Installed ESXi 5.1 on two servers where as installed FreeNAS on the third server and configured it as iSCSI storage and NFS storage.
Problem:
1. Every port works perfectly fine. However, when I keep connecting the ports of the switch to the ports of servers, internet gets disconnected.
2. Interestingly, my wireless internet also gets disconnected, the ports of the switch does not have any internet now.
3. This happens till I connect above 8-9 ports of the switch to the servers.
3. However, when I remove the connection between the switch and the servers, internet comes, wireless internet starts working; and the port of the switch also gets internet connection when I check the internet connection of the individual ports one at a time.
Some more information:i do have internet service provided by Time Warner Cable. My internet speed is as follows:
Download Speed: Up to 15 Mbps
Upload Speed: Up to 1 Mbps
I do have a modem *** router by Motorola which has 4 gigabit ports.Model no: Motorola SURFboard SBG6580 i am assuming it is some thing related to bandwidth of the internet.

At home we have a business Fiber line with 100/100 connection, right now connected to a Cisco 2911 Router.Problem with this one is that it doesnt give the cool neat config options you get on for example the new EA routers, nor does it support uPNP. Now I was wondering if it would be an idea to use the EA4500 (which i have here aswell, though atm not in use) instead of the 2911.does the 2911 offer that much more power and speed that it would be unwise to use a EA4500 on Fiber?
