Cisco WAN :: 857 W - First Ping Timeout
Jan 16, 2011
I know there has already been a couple of threads on this but rather than add my question to the bottom of one of those I thought I would try afresh.
We have an 857W connected to the internet via ADSL. All works very well, however if I ping from an attached PC the first one always times out. If i ping from the router (ping { URL}source 192.168.18.1) I get !!!!! every time. Back to the PC and 'Request timed out' on the first.
The only way I have been able to resolve this is by using no ip cef. It then works as expected, first ping and all. The problem is after much reading, it is not ideal to disable cef.

I have an issue that websites take a few seconds before they start loading, despite about 20Mbps download speeds.I've traced the problem to my E3200: when I ping a website, the first ping times out and only subsequent pings return. If I immediately ping the website again then everything is fine. After a few minutes the problem would resurface (per the specific website). This does NOT happen when I connect directly to my cable modem. This does happen both from wired and wireless devices. Happens on both Mac and Windows.

I am running a Linksys WRT54G wireless router but have my primary computer hard wired to it while my laptop connects wirelessly. In both cases, when I ping my IP's speed test site, I get a solid ping rate of approximately 17-20ms but i also get about 5% failed: timeout's. Now I've seen posts here that suggest wireless interference could be an issue but since my desktop is hardwired into the router, that source would seem to have been eliminated. When I connect my desktop direct to the cable modem the problem doesn't occur.

I have an Cisco EA2700 router and a Motorola SB6121 modem. If I'm connected to the router wirelessly or through any of the lan ports, I can't visit the modem's diagnostics page at 192.168.100.1. If I connect directly to the modem, it works fine. Also I cannot ping the modem through the router, just get a timeout. My ISP is Comcast.

I have a new 3560G to set up a small network for a remote site. I configured the vlan and an SVI as the gateway. The switch is also the DHCP server for the LAN. I configured Gi0/2 as L3 port, connecting to the nearest neighbor. My network runs EIGRP so i advertised the routes into the EIGRP process. The switch forms EIGRP neighbors and learns all routes in the enterprise network. The problems I'm having now are: 1. The switch learns all routes in my enterprise LAN and can ping devices in the enterprise LAN, but I can’t ping any interface on the switch from the enterprise LAN. 2.

I set this up and I can ping all the gateways but never the hosts. I was hoping I could make these links between 6500's a mix of L2 and L3. Check it out. They are connected in a linear fashion R1--->R2--->R3. I can ping from R1 to R3's SVI4 gateway but I can never ping a host on that SVI4. I was hoping that I could use the port-channels between 6500's as routed links or as trunk links depending on the type of traffic....thought it would ease the migration. I suppose I could always get rid of the port-channels and just make separate L2 and L3 links between the 6500's.

How do I, if I even can, adjust the MAC table timeout from 5 minutes to whatever is bigger and allowable?
I would like to also like to change the ARP table timeout as well.

I have a D-Link DIR-825.B1, which I've recently updated to the 2.04EU firmware. The update fixed some IPv6 problems I've had, but introduced an IPv4 problem instead: TCP NATs have a rediculesly low timeout of 60 seconds, which makes the router useless for most protocols.How do I set the NAT timeout for TCP connections?

I would like to know something with more accuration about idle timeout configuration. In particular why is impossible to set "half-closed connections" to a value lower than 5 minutes neither through a policy-map? In my particular scenario, my asa is used to nat mobile phones traffic, it should be advisable to use less than 5 minutes
In my configuration I've set the timers as follows:
.
timeout xlate 0:15:00
timeout pat-xlate 0:00:30
timeout conn 0:14:00 half-closed 0:05:00 udp 0:02:00 icmp 0:00:02

I have several devices on the same subnet and with similar configuration. All of them were entered manually on the ACS server and are configured to authenticate using TACACS+. Some of the devices can authenticate ok, but other will timeout. I did a tcpdump on the firewall port and can see the device sending the SYN to the ACS server but the server sends no reply to the device.

my current setup: Windows XP machines authenticating wireless using 802.1X to a Cisco ACS 5.3 that redirects the request to Microsoft Active Directory. All the statements that I make below are what I have gathered from reading on forums, some of them might be incorrect.
In the ACS Under “External Identity Stores” and “Active Directory”, there is a check box called “Enable Machine Access Restrictions” if it is checked and the Aging time is set to 8 hours and a Windows XP machine authenticates using it’s Domain credentials it will gain access to the network but if that computer is not rebooted after the 8 hours is up, Windows XP will not send it machine credentials again, it will only send the user/pass of the user and will loose access to the network. The problem we have is that most of the users do not shutdown their computers when they go home, they hibernate the computers thus when they come back to the school the 8 hours aging time on the ACS has expired. The ACS expects to see the Windows XP machine send it’s domain credentials again but from every forum I have read on, Windows XP will not send it again until it get rebooted (FYI, Windows 7 will send the proper info, thus they work just fine). In the mean time I have changed the aging time to 8760 hours but this should only be temporary because it is a security risk to have the aging time set so high. Moving forward what are my options to make this work properly?
-Is there a way to fix Windows XP?
-Is there a recommendation on how to bypass this issue but still give us decent security?
-Is setting the aging time so high, a non security issue?
-I guess worst case scenario, the customer can try to educate all the students and staff to reboot their machines every morning?

Faced this recent vulnerability?
[URL]
My understanding is that for ASA 8.4.1 and prior, there's a vulnerability that opening many ssh sessions and one of them times out, the firewalls crashes!
As we have many customers with ASA using 8.2.5(26) (for example) I'd like a confirmation that for fixing that bug I need to upgrade my ASA image to at least 8.4.x.Case that, I believe that all the former firewall configuration must be reviewed because 8.2.x version has many different commands that 8.4.x (for example, NAT)

I have deployed a 2504 controller with EAP-TLS however we are receiving the following errors where it appears the EAP response timeout from the client is expiring and not receiving a reply, this is happening with all clients.
We have three SSIDs one with EAP-FAST working perfectly, and a third with WPA2-AES itis only this where we are seeing the response appear to expire. Running code 7.0.116.0 on a WLC2504. RADIUS shared secrets all ok.

Search for 'DIR-825 timeout' only returned a half page and none were relevant.
DIR-825 2.03NA - The web interface has a ridiculously low timeout value. 60 seconds maybe?
I can't build a list of MAC addresses, e.g., before it reaches the timeout. I try to save.... and I have to log back in. And my changes are gone.
What's maddening is that it WAS working the way I wanted, with seemingly no timeout, until recently when I had to basically re-do my network.

I have just updated myDIR-655 A4 to firmware 1.35NA by the procedure: save config > upload firmware > load config.However after upgrading, my admin page now logout after every ~10 sec of inactivity.I have tried the method where to view the admin page without a style, to be able to set the timeout period, from 5 mins to 3, 8 and 10 mins, but no matter what I set, it still logs me out after ~10 sec.

I have an RVS4000 with FTP download issues. I have the latest v1.3.3.5 software and the latest ISP (1.5). Regardless of any settings changes, my FTP downloads always timeout. I have tried a new basic router and had no issues, so it is not the PC, FTP software, or the ISP. I have even put my PC into the DMZ and still no resolution.

I recently had a firewall that wasn't passing traffic (ASA 5510 running software version 9.1).It turned out it had 130000 active connections. Doing a "clear conn port 53" dropped the active connection count back to 38k, and the firewall started passing traffic again.

I have inherited the support of an ASA5520 running 8.0(3)12 code and I believe I have a pretty simple question here that I haven't been able to figure out on my own. I have a few users that connect to the box via IPSEC VPN client connections. They want to be able to leave up a RDP based connection, for monitoring purposes, for a most of the day, but thier RDP connection keeps getting discounnted after a few hours. The VPN connection never gets disconnected, just the RDP session running through it. I have another box running 8.0(4) code and they can leave up the RDP sessions as long as they like without getting disconnected from the server(s). I have compared the configs of both boxes and don't see any glsring differences in regards to the configuration that would cuase the RDP sessions to either to stay up or be disconnected after an inactivity type scenario.
What to look for in regards to identifying the timer that is disconnecting the RDP session after a period of time.

We are trying to configure our 2106 wireless lan controller to expire wireless users sessions so the user is not remembered indefinitely. We are using freeradius to validate the users login information and passing back a "session-timeout" avpair but the WLC seems to be ignoring this value.
How to configure the session expiration time of wireless users on a 2106?

We're having trouble trying to deploy 802.1x authentication on a brand new site.
Our primary and secondary ACS are located in Paris and the new site located in Toulouse, France. Both sites are connected through the WAN. Everytime a computer/user connects to this new site in Toulouse, ACS 5.2 sends a "5411 EAP session timeout" error message.

I have a 3825 configured as an EZVPN server with 881 routers as clients. One issue I am seeing is that sessions don't seem to time out, such as when a peer's public IP changes. Show crypto ISAKMP peer shows the same host (using device certificates for authentication) with multiple public IPs establishing sessions. I have ISAKMP keepalives configured on the router.

I have a 5505 for a small business that has one web server. The web server has a static NAT entry to an IP address and not an interface. There is an access rule allowing any HTTP traffic to the outside IP of the web server. From the web server I can't access the Internet.
All other computers on the network can access the Internet using a dynamic nat rule that uses the outside interface. The web server is accessible from a computer behind the firewall.
If I delete the static NAT entry for the web server I can get on the Internet.
I have turned debugging on and see that an outbound connection is built and then 30 seconds later the connection is torn down with the bytes 0 SYN Timeout message.
I am running 8.0(5).
