D-Link DIR-601 :: Constant Blocked Incoming TCP Ack Packet Messages In Log?
Nov 27, 2011
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.

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.

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?

I am constantly getting a few errors in my ASA 5510 and 5505 from the same IP. The IP of my NMS server, which has also stopped recieving SNMP data from these two VPNs.
Syslog Id: 713048 Error process payload: Payload ID: 1
Syslog ID: 713902 Removing peer from peer table failed. No Match.
Syslog ID: 713903 Error: Unable to remove PeertblEntry
I have tried to configure ACL to let traffic through. SNMP traffic to be more precise, but since I am fairly new to cisco firewalls and SNMP in general this has proven very difficult.

I have 2 sites connected by a site-to-site IPSec VPN link using ASAs. (ASA5505 and ASA5510 at sites A and B respectively.) There is a UDP data stream that feeds into a Site A server from the internet (packets arrive on the Site A outside interface and NAT is applied to forward to Server A). I need the Site A ASA to redirect these UDP packets over the VPN link to a Site B server instead of to the Site A server.
The source devices can not be reprogrammed with the Site B outside IP. The VPN tunnel is working, Server A can communicate with Server B.

we have a L2L tunnel between ASA 8.2.5 to Cisco Router. Recently we see tunnel is going down and shows messages in ASA about ESP packet discard. Below is the message.%ASA-7-710006: ESP request discarded from x.x.x.x to outside_int:x.x.x.At the same time from router the tunnel shows up but ASA not. We see CSCso 50226 which matches exactly with our issue.As a workaround we were resetting tunnel from router. It comes up and runs for a week.

I've been fighting with my E2500 since I got it back in June with lag, dropped connections, etc. It's a bit intermittent but can hang around for hours at a time when it kicks in. Restarts but the issue always comes back. Most noticeable while gaming online or on a VOIP program such as Team Speak. Generally when it happens If I'm monitoring my Team Speak connection the incoming packet loss shoots up between 20-30%, starting to drop out every other word or so. No out going packet loss. The connection drops are random between computers (I have one mac and one pc in the house) where one will be fine and the other wont, or when the whole system will stay connected and drop all transfer. In the case of this last one it's not my ISP's connection as any streaming happening between one computer and an Apple TV device will also cease. I've also swapped back to my old router (an older model linksys) and all problems have stopped. Fully rebooted and reconfigured the router about 3 or 4 times and am on the latest version of firmware (1.0.003). It was much worse on 1.0.002 but still very noticeable on 003. Also no difference with a different wireless adapter. I've tried the chat technical support but all they did was take 45 minutes to tell me how to reboot my router after telling them I already had.

My router was working fine. Then 1 day I started having slow internet. My ping in games would jump up from ~60 to about 400-800. Did some troubleshooting with my ISP. Seemed like my modem was to blame. So I bought a Netgear one from BestBuy.
Everything was fine. Then 1 day the internet stated disconnecting. None of the computers could see the router in the wireless networks. I found the only way to solve the problem is to unplug the power and plug it back in. Strangely it seems to happen a lot late at night like around 11PM or 12 midnight EST.
Before with my old modem I just had automatic settings and DHCP. With the new modem it wouldn't work so I called DLink and the tech guy walked me through some steps, one of which was changing the ip address from 192.256.0.1 to 10.10.10.1. Whenever I reboot the router after a disconnect the computers say "there was an IP address conflict." Maybe this has something to do with it?
I saw in another topic someone said their router's time was wrong. Mine said it was 2010 so I updated it to automatically sync with ntp1.dlink.com and now it shows 2012. Let's see if it fixes now. My mom's laptop had a similar problem with Skype. For some reason the clock kept resetting to 2000 and Skype would not work (everything else did). When she resets the time to 2012 it starts working again.

I just got a DIR-655, and I got it working, with some effort. However, the wifi stops connecting to the internet every few hours and requires a reboot. Only a reboot of the wifi portion of the router's software, I go to Manual Wireless Connection Setup and save it without changing anything. LAN connections don't experience this.

I'm running a D-Link DIR-655 Hardware Version A3, Firmware Version 1.21. In the past, it has been flaky, and I considered updating to the latest firmware (1.3+ something), but everywhere I read (mainly this forum) said it might be WORSE for the router and couldn't even be downgraded, so I decided to ride it out.
Eventually the problem disappeared and I forgot about it, but now it's back with a vengeance. Recently I opened up a Guest Zone so my neighbors could borrow wifi, and I occasionally run torrents. Torrenting seems to definitely crash the router overnight, while it also seems to randomly bug out, possibly when the neighbors are using the Guest Zone. The Guest Zone might be responsible, but I have no idea.
For what it's worth, I don't think my neighbors are terribly tech-savvy, so I doubt they're filesharing or doing anything risky. They might have malware installed, but I don't know.
Is there a way I can diagnosis my precise issue, should I go ahead and update to the latest firmware to try?

I just got a new 2011 Toshiba Satellite L755 laptop with Windows 7, I also have a 2006 Compaq Presario with the original Windows Vista. We use a DIR-615 router for WIFI connection on both. The old Compaq will keep a connection with no problem and never looses a connection. The new Toshiba will keep 3 bars of signal but will not keep a constant connection to the internet. Do I need to upgrade my router, which I bought the one I have about 3-4 years ago, or could it possibly be a problem with my new computer?

I would like to block incoming traffic from a specific ip on a specific port
This is what I have
source: interface: wan ip address range: 5.xxx.xxx.226 - second one is empty (valid ip instead of x's) protocol: tcp
dest: interface: lan ip address range: both fields empty port range: 139 - empty field
ON and DENY box is ticked name field has some text in it
I click save and get this pop-up: Incorrect source ip address. Invalid format of the start IP address. Current Firmware Version : 2.11 The ip is obviously valid, what should I do?

How to configure my DIR-615 (Hardware Version E1 - Firmware Version 5.00NA) to:
1. Assign/Reserve IP address for 2 machines.
2. Route a web browser to a server on the first machine (port 80) as a default when another computer or smart-phone or device joins my open wireless network.
I am hoping to eliminate any changes to the IP address of the first two computers so that the server's IP address and port are static. I would also like anyone who joins the network to merely open their browser and be presented with the http interface from my server.

I am trying to make my computer support incoming VPN connections. I am using Windows 7 Home Premium on the computer I want to make the connection on.I am also using Verizon FioS internet (comes with default router/modem combo) to which I have the DIR-655 router connected. I am able to connect to both WiFi's fine and they work correctly.I think the Verizon router is set to block incoming VPN connections and I think this is why I cannot get anyone to be able to access my computer / internet via VPN. How I can perhaps forward ports and which settings I would need to specifically change in both routers admin settings so that I can get VPN connections to forward to my computer and be accepted.

I need to block incoming traffic with Dlink DIR 600. I know how to create the rule source (WAN) to destination (LAN) to deny all protocols. But what IP will I put in WAN? IP address of my Internet? Or how can I enter the ALL IP range in source...format for the IP (it's not 0.0.0.0).
I want to do this because in the DIR log section I'm being PING Flooded. I already un-check "Enable WAN Ping Response" but still receiving the message.

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?

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.

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.

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 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.

I having a basic query in troubleshooting E1 link , here im facing packet drop in the link and we are testing by providing local loop and remote loop from the CSU/DSU at local point and at remote point . I have tried ping test while the loop is given at local point and remote point ie i have pinged my local serial interface IP address (eg 10.0.0.1 -local & 10.0.0.2 -remote ) in Remote Loop i could see no errors and drops and also the traffic on the interface output and input is the same(eg input rate 1000bps and output rate 1000bps) .My query is that when i am pinging the local interface IP does the icmp packet travels till the loop point and comes to the same interface(like a boomerang) .
ICMP packet

I have two routers, Cisco 3825 and 2811 connected via a p2p ethernet link. The two sides of the links have Huawei muxes with 100/ full duplex set on their interface. I am facing almost 40% packet loss but the supplier is unable to identify any issues at their end. We have tried setting different combinations of duplex and speed settings but no improvement. When set to auto/auto the interfaces are negotiating to half duplex and I am sure this is the cause of the packet loss. Also I heard of auto-negotiation on MUX ports but supplier confirmed no such settings but only 100 Full duplex. If the router iterface is negotiating to half duplex so I suppose there is some thing with the negotition problem with MUX and router port ?
On C3825 I have a Gig interface whileas C2811 has fastEthernet. I guess Gig interface should not negotiate ? Is there a way to pin point the exact fault to supplier ? Also is there work around for this?

I am not good at networking. My friend wanted me to set up his home network.because the modem is unable to supply a good wireless connection to the rest of the household when the door is closed, a second router was needed.I set both routers to run with DHCP as they have many devices that needs to connect to the router for internet. However, a few hours after setting it up, my friend's pc as well as all devices connected to the second router faced issues. The router's interface showed that it does not have connection to the internet. they are still facing this problem until now.
