No Response From External IP?
Aug 21, 2012
I use Comcast, and am trying to set up an FTP server that I can access from outside my home network. I need the external IP address for that to work, and I have gotten this IP address from IPChicken. I can ping it from the internal network just fine, but when I'm connected to a different network (I've tried two), I get no response, using both the IP address and the associated host name. Of course, I also cannot log into FTP.
I spoke with Comcast support, and their advice was to enable MAC filtering and add the external IP address to it..

I have the following setup:
R--H1
|
F
|
H2
R: 3840
F: ASA 5510
H: Hosts 1 and 2
I am trying to get SNMP info from the router to H2 but snmpwalk errors with no response from router. I can get info from H1 and neither interface on router is preventing SNMP traffic from coming or going.Is there something that needs to be configured to allow SNMP traffic (orginating from INSIDE) to reply? (Also note that there is no Inspect Maps blocking and SNMP versions).

We purchased 4 AP1232AG access points, intending to use 1 as a router and the other 3 as repeaters. We've spent the past week running power to the repeater locations, installing poles and NEMA boxes, lightning arrestors and 12db antennas. That part went very smoothly.
Now I'm trying to access the APs for the first time and get no response. Cisco states that all the units are set to 10.0.0.1 and that I need to use a console cable from my com port to the console port of the AP. Did that. It also states to use a telnet session to assign an IP, using the setup recommended.
The APs will not respond whether I try a telent, serial or web session. The router center light on all the units is blinking green, which according to Cisco means they are set to the factory 10.0.0.1 and that the radios are disabled. Since it's occurring with all of the routers, I've definitely realized that the problem is operator error. I don't have enough experience to determine where my mistake is being made. I used Indigo to try and reach the routers and the Cisco IPSU as well with no success. I've even tried pinging the router's IP and get no response.
I feel certain that I'm simply overlooking some fundamental and basic task to reach the routers to configure them, but I've been to every technical document on the Cisco site regarding the access and configuration of these routers. I simply can't see my error and it seems like the more I read the bulletins, the less clear it becomes. I'm now stuck.

We have an ASA5510 and I am getting absolutely no response from the console port. Not even a blip when I turn it on. If I leave the compact flash in the internal bay, I get Green Power, Amber Status, Amber Active and Green VPN when I start it up. The Flash LED flashes Green twice then goes out. If I move the compact flash to the external bay, all of the other lights remain the same as described above but the Flash LED goes to steady Green. How ever, there is still no response whatsoever from the console port. Have replaced the DIMM but that had no effect. This is a four (4) slot ASA5510 and I have just the one DIMM in slot P13 as described on a post I found. The power supply fan comes on as well as the two (2) fans that cool the heatsink. The other two (2) fans on the expansion module side do not come on.

I have ZyXEL PLA4201KIT Mini Powerline Ethernet Adapter Starter Kit Up to 500Mbps to connect my desktop to the internet and recently i've been getting random moments where i lose internet connection so everything stops working. I have to either restart my comp or take out the ethernet cord and put it back in. my router is next to our tv and i read somewhere that having it next to a big appliance will suck all the power for itself.

Buying a TP-Link W8961ND modem/router. Didn't work at all, except for a vague sense I got that the internet wasn't spending as long 'down' as previously when it did drop.And now today my housemate and I are both connected and suffering these intermittent drops, which become more and more frequent, until finally the internet cuts out and won't return. Now I cannot get the TP-Link router to connect to the internet at all. However, switching back over to the original D-Link router now the internet DOES work, but still only intermittently. As I've been writing this it's dropped out for a couple of moments twice!

I'm using a cable connection with my router and most of the time I'm playing FIFA12 on PS3 i feel like the commands takes a second to respond, like if was a delay. I tried most of everything in firewall settings, port foward, internet settings...

I've been using my pair of ACE-4710s for quite some time and have usually stuck to the Class C Subnet sticky settings, as that's what we migrated from in Windows NLB. In one instance of load balancing I'm trying to create an L4 inspection policy that looks for a certain payload (much like a http header) and would like to persist on this. The problem is that the client portion of the conversation starts with a 'SessionID' of 0, and the server responds with a unique 'SessionID'. If I setup the sticky policy with 'Enable Sticky For Response', I get entries populated in the sticky database, but they all go to the same server as there is a sticky session setup for the SessionID = 0. Is there a way to setup sticky entries on server response only.Currently using ACE DM v4(1.0).

I've got the Di-614+ connected to a Wimax system. The Wimax is plugged into one of the LAN jacks in the Di-614+ (i tried pluggin it into the WAN jack but it does not work). I'm able to use the internet fine without any problems using the wireless connection on my laptop.
The thing is the ip 192.168.1.1 is set to open up the setup page of my Wimax modem. I cant seem to access the setup page of my Di-614+. I tried disconnecting the Wimax jack, and still google chrome just responds with "This webpage is not available". My other option is to hard reset the wireless router. But i worry it will ask for a password and i wont know it.

I've updated latest firmware & installed 5 pieces of WRT54GH at our building. Then I noticed each of them disappear from wireless connections list and IP scan list (no ping response). If they might not response to pings but they serve as switch without any problem, I mean there are no wired connection problems, they work as switch all the time. The problems are -again-
1-) Wireless lost and / or 2-) Ping response lost
Turning them off and on again will fix them. But I'm tired of bosses who complain about their faulty pc connectivity.
Don't they run 7/24? I tried to restart them on every 12 hours programmatically/remotely but it couldn't work.

I have a brand new 2911 router out of the box. I attached a terminal to the console port and watched the bootup sequence. I get the "press return to get started" at the end but I can't get any response. I just used the same cable and terminal on a 3750 switch and an ASA. What am I missing?

After implementing TACACS, one of our routers takes about 8 seconds to response to any CLI command. We have no problems with other devices in the same location with the same AAA configuration. The router is talking to the ACS server (ACS 5.3) and the logs on the ACS server look normal for the router as well.

I am trying to track down an application response problem on my network (the traffic goes through a 6509 and FWSM).I noticed in one of my WireShark captures, that the client at times seems to be sending ackowledgements (ACKs) over and over again, and I'm not sure if this indicates a problem/ retransmission.
Basically, a web server is delivering images to the client, but end users are complaining of slowness and freezes.Wire-Shark has not flagged this as a problem (comes up "green")

I am having intermittent problems with wireless connectivity to this router. It stops responding to requests completely but existing connections continue to function.
The hardwired connections also are functional but I cannot get to the admin console to see what is going on. The router is currently not being used to connect to the outside world. When it was before this situation still existed. I am using firmware version V2.0.1.3

Periodic Slow Response 2821 (300+ms, 1 minute) My solarwinds NPM reports very slow response times from my satellite clinic.Often times it is 300ms to 600ms when it should be 10-15ms. CPU does not seems to spike, the memmory does not seem to spike The bandwidth does not spike.It happens mostly during work hours about 10 times a day Solarwinds reports the delay and then 2 minutes later it reports normal activity
I have broadcast/multicast control on the switches? We have static route for our network meaning no routing protocols ?We have 12 other clinics with the same configs and they are fine?I have double checked the configs but I am not holding my breath on that item?I have rebooted the router without affect
I have not replaced the cable to the demarc on either side of the WAN connection?I have not reseated the service provider T1 cards?I have not reseated the T1 card on either router.

I can connect to the free wireless with no problem on my company laptop. Last night, I was using my personal laptop (as I have been for 2 weeks) on the wireless internet when I suddenly lost connection. In the Network and Sharing center of Windows Vista it shows a connection to the router but an 'X' between the router and the internet. When I run the diagnostic I get "Cannot communicate with primary DNS server (4.2.2.1)" The it says "Network diagnostics pinged the remote host but did not receive a response".

First few attempts to load a web page after a reboot are okay, then it begins to stall with no error, or sometimes an "empty response" error message. I simply cannot load web pages. Checking mail sometimes stalls. When this happens, the Thunderbird process hangs around after I've exited the application using 50% cpu. I didn't discover this until just recently. Even when connecting to my own router 1 hop away, the admin web page timed out. Other things like downloading software updates and online help seem to be unaffected. FTP connection sometimes stalls. SSH takes forever (~10 seconds) to get a login prompt. Connecting directly to the cable modem has no effect. No other PC in my home has any problem getting online. I've tried changing DNS servers with no luck. Same problems with Ubuntu running in a virtual box in Windows. I can get online in Safe Mode. During the malware detection there was a question about my proxy settings, which showed up in a system scan, slowing me down. I didn't think that was contributing to the problem, but I've since deleted them and still no improvement. I just completed a round of malware detection in the other forum and my system appears clean, so I decided to come here and give it a shot.

I have a brand-new WRT160N router (just installed FW v3.0.02) that I am using in mixed mode, 20MHz only, Channel 11, not filtering anonymous requests, beacon at 2306, RTS at 2307, fragmentation at 2346, MTU at 1400.
These settings bring the response from a simple ping command over the wireless network down to approximately 6ms on average, which is good. However, when I still noticed inconsistency with my internet response over wireless, I decided to do a test.
By simply running the "ping" command on 192.168.1.1 (the router address) over the wireless network repeatedly (approx 3 seconds between commands), I can see that approximately every 65 seconds or so, router response time increases to over 100ms for a few seconds, then decreases down to 6 ms or so for another 65-70 seconds. See the chart below. The interval looks pretty consistent to me, with the exception of one stretch where it goes for over two minutes without a spike. I see this pattern regardless of what else I'm doing over the network. I do not see this behavior running the same test when physically wired to the router (ping response time is a flat line at 0ms).

I need to remotely monitor a WRT45G from a remote host on the Internet. As such, I want to allow ICMP ping replies on the public Internet interface. However, I have found no feature to allow me to do this. Similar Netgear devices do allow this feature. I suspect the answer is, "you can't do that".

We`re using a WLC 5508 with SW 7.2.103.0.The most things are working fine, but i have a problem with the web auth.
Setup:
- Max Concurrent Logins for a user name is set to 1
- Max-Login Ignore Identity Response is set to enable
- Web Authentication Type is set to customized
The Problem:
- the user "test" is logged in at device1 (working), the same user "test" try to login at device 2 (is not working, fine!) -> login is not accepted, WLC redirects to the INTERNAL Web Login Page.The problem is the redirect to the internal web login page after failed login. If i try to login with a not existing user, the redirect is working perfect to the customized web login.

I'm having trouble connecting using this new card i bought. i have installed the latest drivers and i can find networks and the signal strength is good too but when trying to connect after ive entered the passkey i get the message " no network found" or "did not receive response from router" or something along those lines. i can connect with my older card which is a wmp54g but that one shows less signal strength and my connection breaks from time to time (hence the upgrade to wmp600n) on a sidenote, my wmp600n card works perfectly fine under linux but i want it to run in windows (mainly for gaming) Im running windows vista 64 bit and the wmp600n has the latest drivers installed.
