PC Sending Packets To Random IP's From A Range Of Ports?
Aug 27, 2012
So this is somewhat of a strange issue. I have a program called PeerGuardian 2 and it allows me to simplistically see the packets being sent to and from devices on my home network. It's showing that my computer is sending packets to random IP addresses, some of them reoccur, on a massive range of ports all going in order.
(example)
From 192.168.1.253:6812 - To 74.120.148.2:80
From 192.168.1.253:6813 - To 74.120.148.2:80
From 192.168.1.253:6814 - To 74.120.148.2:80
From 192.168.1.253:6815 - To 74.120.148.2:80
From 192.168.1.253:6816 - To 74.120.148.2:80
From 192.168.1.253:6817 - To 74.120.148.2:80
This happens in spurts and it usually sends 20-40 to varying IP addresses in a matter of a few seconds. I asked my ISP if they understood what this was and it stumped the technician I spoke with. I also have run multiple virus/malware scans and everything comes up clean.
One Day the internet is fine the next day The Internet Stopped working. The problem is my pc is sending packets but not receiving any i though it was a bug or something so i restarted my pc after i restarted my pc the internet was working fine until a couple of minutes passed it stopped receiving packets again.i tried resetting the modem but nothing worked.I tried winsock fix or resetting TCP/IP and stuff but nothing workscause its starting to frustrate me.
Our computer is sending but not receiving packets. We've tried 3 different wi-fi adapters, and that wasn't the problem. We have no idea what's wrong? It won't pick up any wireless signals by the way, and it works fine while connected via Ethernet.
Alright, so we have about six computers on average all on at the same time, working just fine, last night one of the laptops just, stopped working, saying there is no internet access, With every attempt it doesn't send any information. When I disconnect it from the wireless, then reconnect it, it immediately receives packets but won't send any.
I have a laptop computer with windows 7 and im having trouble connecting to my wireless internet. It says that im receiving packets but not sending them. I have tried to troubleshoot the problem and it says that the default gateway is not available. I am not sure what is happening with it, it started having problems while at a starbucks, and now the wireless and the LAN is not working on it.
i have an acer aspire 5315 and im running windows vista home basic, My wireless has had no issues at all until i came to oklahoma yesterday and my internet will not connect to my dads wireless, but at my moms it had no issue, and at the airport i connected to there wifi with no issues also, is there some kind of setting that gets changed when you connect to the internet in the airports that wouldnt allow you to get on your internet at home?
Few systems on my LAN stops recieving packets but sending, this happened after i changed my switch, i run xp professional. i have tested cables, NICs,etc.
I can't connect to the internet. When I double click Local Area Network under Network connections it says it has both sent and received packets. It is set to automatically acquire an ip address. The computer is connected to a router. I can ping 192.168.1.1 but when I try to reach my router's settings it says page can't be loaded. I tried to hook the computer up directly to the modem and connect that way. It said it was connected and it was sending packets but I still couldn't do anything. I've turned off the windows firewall. The computer is Windows XP SP1

Have a Cat 4507 with Supervisor 7-E, setup configuration to send NetFLow information to an external server, everything worked great but after 2 weeks, the exporter is showing zero packets sent and the following error is at the console:
I've been having this problem on my desktop and it's really annoying when i try to play online games that need a constant connection.I have Windows XP and i'm using a wireless connection via a wireless USB adapter. The problem is that the internet is running fine but at random intervals it starts to not send or receive any packets. This will usually cause my to disconnecting during a game causing other players inconvenience. After I d/c the internet will usually take 5-30 seconds to start sending and receiving packets again and regain connection.
I just bought a SG200-18 in order to use LAG between a backup server and multiple computers and servers. Servers are supposed to all use 2 links and computers only 1.
As soon as I activate LAG on port 2 and 3, no matter what is connected on the switch I lose access to the switch interface (luckuly, it's still working on port 17 for a strange reason) and all computers / servers connected are randomly losing the network access. Everyrhing start to be slow but most servers and computers don't lose access to the internet. Browsing a web site will suddenly take ages but... it will work eventualy.
I already used LAG on other switch without a single issue.. The only uplink I have is to the router and I know that I don't have any issue with network cables....
So what am I doing wrong ??? I didn't even try to configure the TEAMING on the servers, just creating LAG on the switch will kill everything Oo.. I'm starting to think that my SG200 is dead out of the box.
I'm preparing myself for CCNA exam and i started doing a lot of different examples. I've got problem with Packet Tracer when i'm trying to apply some security settings for the range of switch ports in default VLAN 1. I might just demonstrate my commands so it will be easier do understand.
Using CCP I am trying to create a NAT entry for a range of ports. CCP window for a new NAT has only one entry for the port #. Is it possible to set uf port ranges in 877 router?
I've an ASA 5505 as my gateway for my internet at home. I've one public IP, so I use Port Address translatetion for my internal clients.
Now i wanna setup a FTP server, on a internal client. I will use Filezilla FTP server. I'm running the FTP server in passive mode, since the FTP server would be behind my ASA firewall/nat device.
I need 50 ports for the passive mode to be running.
I will use port range 50000-50050. I can easy make a firewall rule (access-list) that permit that port range.
But how do I PAT(NAT) a port-range on the ASA device? I can only figure out how to NAT one port at the time.
I have a network with multiple servers behind a PIX with 6.3 on it. I have one public IP address, and I'm using NAT. I'm currently trying to port my Exchange server to a cloud host, and the vendor is requiring I open up a wide range of ports for MAPI, basically ports 1024 on. What would be the command to forward all of the trafic cominto/from that broad range? if I could simply route all trafic to and from their two IP addresses to my email server, that would accomplish the same end goal.
I am new to the RV180W. I am running the most recent firmware--version 1.0.1.9.
I am having trouble getting FTP to work with my QNAP NAS.
QNAP indicates that I should forward ports 55536-56559 to my NAS. I created a custom service to accomplish this, and then, under port forwarding, I selected the service and forwarded it to the private IP that corresponds with the NAS.
However, the port forwarding configuration only allows me to specify *ONE* internal port. With other routers I have always specified the same private port *RANGE* that corresponds with the public ports that I have opened up.
I am trying to add a couple VOIP phone units that do not have their own router. They are designed to run of the existing router and have three ranges of UDP ports opened up. They also do not advise using internal (private) statics on the phones. So what they are asking for is three different ranges of UDP ports to be opened up to all behind the router?
I cannot figure out how to do this (or if it is possible) with a RV016.
I have an ASA 5505 running 8.4(1), and I'm configuring it with ASDM 6.4(1). The outside interface is configured with a single static address. I have a few services port forwarded sucessfully to three different servers on the inside network.
I need to make a media proxy on a SIP server available to the outside. It requires a large range of forwarded UDP ports for the media channels.
I tried adding a network object NAT rule like the others I'm already using to forward HTTP and RDP. I entered a range of ports for the real port and the mapped port using the syntax 60000-60999. ASDM accepted it, but the NAT rule list displays "Any" in the service column. When I apply the change, I get the following error:
nat (inside,outside) static interface service tcp 60000-60999 60000-60999 ^ ERROR: % Invalid input detected at '^' marker.
How do I forward a large range of UDP ports from the outside interface to a single server on my inside network? I'd like to use ASDM, but I can switch to the CLI if that works better.
Network running about 60 computers, most of which are running windows 7 professional. Some are on a domain, some are not.At (seemingly) random times, some computer on the network will lose the ability to browse websites (including the web interfaces of networked devices). I can't identify what circumstances cause this to occur. I only find out about it when someone calls me.From the affected computer:I can ping sites I can ping our Cyberoam UTM (which acts as our DNS, DHCP, and firewall)disabling/enabling connection doesn't fix the problem releasing/renewing ip doesn't fix the problem flushing dns doesnt fix the problem uninstalled antivirus on two test machines, problem still randomly manifests.replaced the Cyberoam with newer model users have claimed that if they wait a long period of time (40+ minutes) the problem sometimes resolves.rebooting the computer resolves the issue until it randomly occurs again changing the computer's mac address also resolves the issue until it randomly occurs again.
We have an ASA 5505. 5505 comes with two default vlans 1&2 with each of them marked as inside & outside respectively.My query is , if i do not want to use vlans on 5505 and only want to use the Ethernet ports as pure physical layer 3 ports, is it possible?i.e. i want to assign a layer 3 ip address on eth0/0 and eth0/1 and make them as the inside & outside interfaces rather than vlans. is it possible to do away with vlans in 5505 & will it work otherwise?
Is there a way to associate spare firewall ports with another port that is being used..For example...int gi 0/2 is being used currently for my web dmz. Its ip is 192.168.10.1..Is there a way for me to associate gi 0/3 with the same layer 2 as gi 0/2 ?
In my webdmz I use 2 ACE 4710 proxys in FT mode. I used a layer 2 switch to connect firewall and proxys together.
I would like to eliminate this switch if possible..and connect both 4710's (layer 2) direct to firewall.If I could make gi0/2 - 4 part of the same vlan, then I would be good to go.
How many of the 881 switch interface ports can be used as router ports, have used the 877 etc where i can use 2 but need a low cost router that supports 3 for routing. (needs to be physical ports)
One of techs accidentally connected two access ports from different switches together. Since then, LMS is alerting them as being Link ports down. I tried to default the config and set them to access ports without any success. what I should do in LMS to recognize them as access ports?
No School havn't own email server, Just we want email within the Lab. (There are 20 PCs on all PCs Windows XP (Service Pack 2) & MS Office 2003 installed.Now tell me how can we send/receive email via using outlook.
