D-Link DIR-655 :: Blocked Icmp / Tcp Packets And Udp Timeout?
Jun 1, 2012
got this problem within the last few days
UPnP renew entry 255.255.255.255 <-> 68.98.71.182:61041 <-> 192.168.0.197:61041 UDP timeout:-1 'Teredo' (this one repeated 13 times just in that 1 info slot)
Blocked outgoing ICMP packet (ICMP type 3) from 192.168.0.197 to 109.185.100.195
Blocked incoming TCP packet from 108.170.42.83:80 to 68.98.71.182:36792 as SYN:ACK received but there is no active connection
this goes on for a multiple of different ip's and i believe its due to the fact that the game i play is p2p
QoS is off spi is off udp and tcp endpoint independent firmware version 1.21 i am using wireless cable isp using motorola sb5101 i believe i port forwarded the ports used for the game but that didnt work so i put my computer into dmz. I've also noticed a lot more jitter then i used to have and my upload speed is down about 4mbps. Was thinking it might just be outdated firmware?

I am using a Pix 515 with IOS 8.0(3).I have in my access list on the outside interface.......access-list outside_access_in extended permit icmp any 12.23.34.0 255.255.255.0 echo access-list outside_access_in extended permit icmp any 12.23.34.0 255.255.255.0 echo-reply.......in order to allow ping requests and ping replies into my inside network. This certainly works since I can ping the inside from outside and vice versa, but in the ASDM display of access rules, the hit count for these two lines is always zero. If I run 'show access-list', the hit count for these lines is non-zero.
Why doesn't the hit count show up in the ASDM gui display?Also, I have read that the PIX does not treat ICMP in the same way as TCP or UDP and there is no stateful behaviour towards ICMP. However, if I set up a continuous ping from outside to inside and then disable the above access list rule allowing echo requests towards the inside, the ping continues whereas I would expect it to stop.
In the config there is 'timeout icmp 00:00:02' if there is no stateful connection for ICMP, why is there a timeout value for it?

At this moment we have a Linksys x3000 configured as modem on a ADSL connection (PPPoA)From our monitoring server we send ICMP packets to see if the connection is alive (or not).The problem is when we disable the ipV4 SP1 firewall and do not tick the: "Filter Anonymous Internet Requests" , we still receive connection timeout's from outside hosts. Is this a bug? And if not; how can we enable ping from outside networks?We really want to enable ping because of the monitoring software.The firmware is the latest version: 1.0.0.1

I've a big problem with a loss of packets ICMP sent by different hosts in differents VLAN. Here my architecture:
Core Switch : 2 Switch's C6509 (Version 15.0 (1) SY1)- Mode VSS - One lien VSL , the other link is defective.Access Switch: C3750 , Connected to Core Switch through 2 fibre optique wires.Topology: redundant ring
When I send consecutive ping message I found always a missing of packets . Furthermore When I insert the "show ip traffic" command., the parameter "bad hop count" increase after a loss of packets. I've 2 hosts connected in my network and they send packets with TTL =127.
In the Core Switch I haven't configured the MEC because it gave me troubles with the packets multicast.

I have a cisco 2811 router set up as a nat/firewall gateway for my network. I've configured it for CBAC on using ip inspect and an access list.What I want is to use audit-trail to record network traffic (which means sending syslog messages to a server) concerning established sessions from my own network to locations in the outside. If i configure this using ip inspect audit-trail and no ip inspect alert-off, the configuration looks like this: [code] which works just fine, but there is the matter of icmp packets.
Since i use polling software that needs to check some machines in the outside part of the network, it is only natural that several icmp sessions are established through the Inspection Rule per minute. The problem is that since these sessions are recorded along with everything else, my syslogs are flooded with these (since i am using logging trap informational) to the point that more messages are generated about icmp than all other traffic combined, especially in non-working hours.What I am asking is a way for the audit-trail to be selecively disabled for icmp, so that the outgoing (echo) &incoming (echo reply) sessions can be established without generating syslog messages.

I would like to passthrough ICMP 8 (ping) requests through the DIR-655 to my server. I found where to allow the router to respond to ICMP 8 requests, however, I do not want the router to responder, rather the server itself. Is there a way to pass these requests through to the server?

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?

Yesterday I had the snapshots setup to be sent to my gmail account and now they've been blocked as spam. Is there anyway to get around this? The motion detection area is set to 90% so I see why I'm getting a bunch of snapshots. Is there a setting I can change on my gmail account or is the only option to reduce the percentage? I'd prefer to get all of the emails.

Is it possible to get both allowed and blocked web access logging? I'm using the 2.06NA firmware and no matter how I configure the router, I just can't get it to work, so either I'm missing something or the firmware has a defect, I hope its me, but I fear its a defect.

On my network I have a Netgear ReadNAS connected and I'm using an add-in (ReadyNAS Remote) that simplifies the log in to for both internet and LAN-users. However, I get a lot of the following entries in the log when that add-in is being used.
When an internet user log in via ReadyNAS Remote: "Blocked outgoing TCP packet from 192.168.0.xxx:3649 to xx.xxx.xxx.xxx:50125 with unexpected acknowledgement 3320366884 (expected 754541166 to 755655246)"
When a LAN-user log in via ReadyNAS Remote: "Blocked incoming TCP packet from 69.xxx.xxx.xx:80 to xx.xx.xx.xxx:50329 with unexpected sequence 3004123085 (expected 3004136875 to 3004393915)"
how to prevent them from occuring?

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've been fighting with getting VPN connections working properly with my Dlink router. I set up virtual servers for PPTP and L2TP and could usually get the first attempt to work. Subsequent client connections would always fail.The logs display the following-Dropped GRE packet from 192.168.0.10 to 64.232.xxx.xxx as unable handle packet header. Blocked incoming GRE packet from 64.232.xxx.xxx to 76.105.xxx.xxx.What seemed to fix it was going to Firewall Settings and setting UDP Endpoint Filtering to Endpoint Independent and TCP Endpoint Filtering to Address Restricted.

I'm new to networking (at least at this level) and need some guidance. First, I have an Actiontec MI424WR (Rev. F) Coax Verizon Fios modem that I use as my home networking wireless router. From a LAN port on that I've connected a cable to the WAN port on my DIR-655 which acts as my gigabit office hard wire/wireless router. I need to keep the home network and the office network separate.All of my computers are Windows, either 7, Vista or XP.Connected to my Dir-655 on the office network are 2 wireless computers, a printer, an IOMEGA 1TB Home Personal Cloud NAS HDD, plus 2 desktop computers.The DIR-655 is set with a static IP address matching the range of the Actiontec. The DIR-655 is set for DHCP for the devices on the network (although 2 of the computers have static IP address).
When the DIR-655 had a Dynamic IP address set by the Actiontec, the IOMEGA NAS HDD kept losing connection with all the devices on the network. Only after I set the DIR-655 to static IP did that stop and everybody started to play nice. I'm not sure why that would make a difference, but it did.But regardless of whether it is set to dynamic or static, no computer on the network or program, even third party programs, can connect to ANY of the time servers out there... and I mean any of them. I've tried at least 20 or more of the standard and not so standard ones. The DIR-655's time is off, and it is set to get time automatically. None of my computers, or my IOMEGA NAS, can access time. The Actiontec, though, seems to be set correctly.Everything connects to the internet just fine. Web, email, auto product upgrades. Fine. So far it's just the time server thing which troubles.I done everything I know how to do to enable Port Forwarding through both routers for NTP > UDP 123 since that is the standard port for the Network Time Protocol, but I could have easily screwed that up.

Using a Samsung Galaxy S2, iPod Touch 3rd Gen, and Nook Color, they are all experiencing retry problems, even when 3 feet from the DIR-601. When I use them my log gets filled with messages like:Blocked incoming TCP Ack packet from 192.168.100.201:2926 to 209.85.145.113:80 with unexpected sequence On the devices I see the downloads/content taking a long time to appear and often I get a blank page or "Retry" messages. I purchased two DIR-601s and get the same problem with both. They are both running 1.02NA firmware. The WLAN is Time Warner cable modem. Prior to this I had a Linksys WRT-54 that gave great performance, though just at B/G speeds. I was hoping for a performance boost but right now the N speeds are slower than B with the retries.

In trying to make sure it was NOT wide open to the internet (amongst many other problems of setting it up, which I ,may address later if I can actually connect to the thing ever again) I told it to only accept connections from a range of address inside the LAN. Now it wont accept anything except telnet from the LAN.Short of wiping out 6 hours of trial and error configuration and resetting it, are there any other options I can exercise via the telnet interface?

I'm using the D-link dir-300 wi-fi router. Cable internet connection. PC is connected to the router by the cable and the laptop via wi-fi. Both machines have the same problem - after some time, although there are no package loss when I'm pinging anything, some services report "connection timeout". Such as PvP.net, EA Online and Turbofilm.tv. Soft reset, hard reset didn't solve anything. Although when PC is connected straight to the main internet cable - there are no problems at all. [code]

I have a DIR-825 with 2.60VT firmware (rented from Videotron).
Even though the manual says the stateful firewall should have a timeout on connections of 240 seconds or 7800 seconds, all of my connections start at a mere 120 seconds. I'm having trouble with IMAP IDLE pushing e-mails because the connections timeout so quickly (before any stay alive can be sent). A connection to the e-mail server gets opened on 143 (Videotron) or 993 (encrypted - google, e.g.), and I see the connection on the Internet Sessions page, the timeout starts at 120. When it hits 0, the connection is no longer displayed (it is not renewed), and the IMAP IDLE ****s out because the server can't find the client (i.e. the connection has been closed). But it's not just on those ports or servers. ALL of my TCP sessions begin at a mere 120 seconds! Even for a home router, isn't this way too low?
confirm that their DIR-825, on the Internet Sessions page, shows initial timeout values of greater than 120 for a TCP connection? I would love to see a picture of that screen showing higher values. Does it start at 240? Do you ever see a connection start at a timeout of 7800?
I see no way of changing the timeout value. Is it possible to force connections on certain ports to begin at a higher timeout value?

So I just bought a D-link DIR-655. It's a B1 hardware with the 2.00NA firmware. After a few hours the DNS server in the DIR-655 stops responding. This happens on all of the PCs connected to it (both wired and wireless) who have their DNS server set to 192.168.1.1. The only way I've found to recover is to reboot the router, change something in router's the configuration causing the router to re-initialize, or to ping an external site from the ping test console. When this happens the external ISP DNS server are still working (confirmed by NS lookup testing manually setting them).

I've been running into an issue for the past week or so where my wireless adapter intermittently can't contact my router.When it occurs the network connection reads as having limited connectivity. I'm unable to send requests to load webpages, and videos and the like stop loading. Sometimes the network disconnects entirely. After this occurs, I can't connect again for a few minutes. My connection consistently reads as having 2-3 bars available. The issue tends to occur frequently, often every 15 minutes or so. Strangely enough, I have been able to play bf3 online for over 40 minutes without connection problems (I quit before any occurred - not sure if any would have). So far I've tried the windows troubleshooter, updating the driver to my wireless networking adapter, manually assigning my network address (tried 192.168.1.4, 192.168.1.5, etc), setting my 802.11b preamble to "Long only" and performing a system restore. I have rebooted my machine as well.
My technical specs are as follows:I'm running Windows 7 Ultimate N 64 bit edition with service pack 1. System has 8gb Ram, an i5-3570k processor and HD7850 graphics card. Motherboard is the Asrock Z77 extreme 4. My wireless network adapter is the TP-link TL-WN722N. The adapter was working fine for some time before this issue appeared.My router is an old U.S. Robotics Wireless MaxG Router. It seems to work fine with other computers in the household, although it does require fairly frequent power-cycling. Running ipconfig on the command prompt while the internet is working returns:

I'm trying to set up a website filter on my DIR-601. I created a policy for 2 MAC addresses, with a schedule from 10AM-6PM, selected "Block some websites", and disabled logging. Under website filter, I added some entries, and selected "DENY computers access to ONLY these sites". When the policy is enabled, and I try to access one of the blocked websites, it gets blocked correctly ("The URL access was denied by administrator.") However, for all other websites, I get "server unexpectedly dropped the connection" errors, eg "Safari can�t open the page [URL] because the server unexpectedly dropped the connection. This sometimes occurs when the server is busy. Wait for a few minutes, and then try again." or in Chrome "No data received. Unable to load the webpage because the server sent no data." This happens with ALL non-blocked websites. I'm using hardware version A1, firmware version 1.01NA.

For about a month or two now, I've not been able to connect to my router's admin page @ 192.168.1.1 I am using a D-Link DSL-2680 router.
Whenever I go to connect to 192.168.1.1 in my Web Browser, it just sits there trying to connect and does nothing. But eventually after some minutes I get the error: 'This web page is not available The web page at http://192.168.1.1/ might be temporarily down or it may have moved permanently to a new web address. Error 101 (net::ERR_CONNECTION_RESET): Unknown error.' Here is a screenshot:
I tried pressing the reset button on the back of my router, but it would just sit there with the green power LED and another green LED just flashing constantly (I assume this is the ethernet 1 cable LED) and this happens for more than 10 minutes.
All I want to do is just port forward my game servers again without the use of Hamachi or other programs

I bought a DIR-655 a less than a year ago on amazon, and it was working great up until about 4 weeks ago. Ive noticed that it has been dropping alot of packets while I am gaming on my computer. I would run about 95-98 ping usually and now it jitters every 5-10 mins or so from 95-98 to up to 500. It is really troublesome during games and I dont know what to do. Ive tried disabling QoS and still nothing. I run on wireless G and N with auto 20/40 mhz. Standard WPA(personal) and it was running absolutely great until now. I know its the wireless because I have hardwired it into my laptop, both from the router and just the modem itself with no problems whatsoever. I dont know what to do about it.
