I have the following LAN setup: I am trying to ping the Wireless Access point (10.60.1.1) from the Cisco Router (172.16.88.21) but I am not getting responces. I can however ping 10.60.1.1 from server (172.16.88.36). Tracert from the server shows that it is going through the Rotuer and Firewall.
View 8 RepliesI'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 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".

View 7 Replies View RelatedI'm trying to configure an ASA firewall (FW2) for syslog and tacacs and am experiencing strange behavior. Both the syslog and ACS server are on the inside of another firewall (CoreFW). Whenever a log message is generated on FW2 the request is dropped by CoreFW and message '%ASA-4-313004: Denied ICMP type=0, from laddr FW2 on interface outside-b2b to syslog01: no matching session' is displayed. The same thing occurs for tacacs.
It appears that the syslog and ACS requests are generating ICMP echo replies, which the core firewall drops since no session exists on a lower security interface. I have access lists configured on CoreFW to allow the syslog and tacacs requests.
FW2 is running asa825-k8.bin, CoreFW is asa824-k8.bin
We have Four 2960S Switches in Stack. We have created Multiple VLANs. While Pinging from Member PC to Member VLAN IP on Switch, we are getting Higher TTL response & Some ping breaks for One Particular VLAN. While pinging from Member PC to Member PC, we are getting Normal Ping Response.

View 3 Replies View RelatedI replaced my old wireless router with a Cisco Linksys E4200, running firmware version 1.0.02 build 13 May 24, 2011. About once a minute the router sends an unsolicited DNS message to the IPV4 multicast address 01:00:5e:00:00:fb with a destination IP address of 224.0.0.251. The unsolicited message is a DNS response with source port 32784, transaction ID 0, flags 0x8400 (standard query response, no error), questions 0, answer RRs 2, authority RRs 0 and additional RRs 1. The two answers both relate to the router itself: one has Name Cisco18738.local, type A (host address), class 1 (IN), cache flush true, time to live 1 minute, data length 4, and the address of the router. The other is the reverse of the same address. The additional record is for Cisco18738.local, type NSEC, class IN, cache flush true, time to live 1 minute, data length 5, next domain name Cisco18738.local, RR type A (host address).
When my desktop computer receives these messages it logs an error, for example: "Jun 23 07:39:22 sauterws02 avahi-daemon[1067]: Received response from host 10.146.9.1 with invalid source port 32784 on interface 'eth0.0'" The 10.146.9.1 is the router's IP address. I also see these messages on the wireless link from my laptop.I suppose the E4200 is generating these DNS messages in a misguided attempt to make sure there is no old information about its name. Is there a way to turn them off? If not, is there a way to report this to Cisco as a bug?
I am trying to recover a WRT54GS v1 router from a bad flash. The power light is blinking and would not accept pings. Since I figured it was already hopeless, I attempted shorting pin 15 and 16 which cause it to start receiveing pings. My problem is it won't accept the tftp flash, I've tried both cmd prompt and auto upgrade utility. Upgrade utility says "Unable to get response from the server" however it is still accepting pings. Cmd prompt TFTP says it can't read from local file. I am using windows XP. Code...

NetAdmin at brach B says they are no QoS configured which prevents ping at packet size of 1500 bytes. I don't have rights to access my brach B router and check the configuration. I am not able to pin point whether it is some configuration issue at my brach B router or ISP issue.

View 5 Replies View RelatedI 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..

View 1 Replies View RelatedWe 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.

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.

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).
