Increasing Bandwidth For Internal Network Not Internet?
Dec 4, 2012
ok i have setup a subnet on my uncles network on which i am running a domain with server 2008. i am using a dlink di 624 router and wanted to know if i upgraded to a 300mbps router would this increase the bandwidth within my network?i know i am limited to what i am receiving from my uncle who is also limited to what he is receiving from the ISP. im not worried about internet speed. i want to increase client to server speed for both lan and wireless.

Even without Open vSwitch, and using the stock, Linux bonding module with 802.3ad mode I had the same problem.
From what I have read about bonding, it seems like if you bond (for example) 2x 1Gbit Ethernet connections on two servers (ie so both have two ports bonded), then if using something like 802.3ad, a file transfer should utilize both ports, and you should see a throughput of 2 Gbit/s. So this would be an increase in throughput and bandwidth, right?
But, what I generally see, is for any single TCP connection, only one port is ever utilized at a time.So for example if I'm SCPing a large file from server1 to server2, I generally see that the scp session is only using one interface, at 1 Gbit/s. I can then also run a second SCP session which will use the second port, and also move at 1 Gbit/s.
This would be increasing the bandwidth, but not the throughput, correct?Which of these behaviors is what I should be seeing with 802.3ad? I guess it depends on the hashing method? Is there a hashing method which will allow a single connection to be spread over two interfaces, allowing 2Gbit/s transfers?

In the bottom floor there are three computers, an iMac computer that receives an average wireless Internet signal, desktop computer and a laptop.I want to take care of the desktop computer and buy a network card, the next card:TP-Link TL-WN951NNow it has three antennas, each of its reception range is 2 dbiI should buy three of the 10 dbi antennas and connect them to the network card?It will give a good solution strong wireless signal and good speed?

The infrastructure has PIX515E as the Firewall and few Web Servers and Database Servers inside. Is it possible to retreieve information regarding the bandwidth available at the outside interface of PIX (Internet link utilization ) utilized by each of the nodes seperately? I could use SNMP to get the overall data transfer at the Outside interface of PIX but isit possible to get utilization details of individual nodes ? Is Netflow an option ?

My router just dropped the internet. I checked with ISP and confirmed that their modem is fine - I can connect direct into that - but the DIR-655 won't connect externally. I've tried wireless and wired and can connect fine to the router, but it is like the firewall has reset itself or something. at the moment I'm surviving because of a 30m long ethernet cable to the modem going out the window and round the house!

I purchased a WAP4410n for our small office to provide wireless access to our internal network to laptop users. I have configured the device as simplistically as is possible, but although I can get my laptop to connect to the AP (verified by managing the device wirelessly as well as by pinging the IP address) I can not get to any other IP address on my internal network nor the internet.I gave the device a static IP address - 192.168.1.50 subnet 255.255.255.0 with a default gateway of 192.168.1.254 which is my 2811 router. I set up a WPA-secured SSID.
A second problem I have is that if I set up my laptop wireless card to get its' IP settings form a DHCP server, it picks up a 169.xx.xx.xx ip address - it is as if the AP is not passing my DHCP broadcast / response through.

I have an ASA 5510 configured 3 interface Internet_AAPT, Internal_Network and Server_Network. The server network works fine as is able to connect to the internet and services like port 80 work from the internet in. But from the Internal_Network can only get to the server network but not internet (6May 13 201214:17:4030201310.153.111.21253663199.47.216.14880Built outbound TCP connection 42508 for Internet_AAPT:199.47.216.148/80 (199.47.216.148/80) to Server_Network:10.153.111.212/53663 (10.153.111.212/53663).

I'm wondering if there is an easy way to monitor how much bandwidth is being consumed at any given moment for a home network.specifically, for the incoming/outgoing internet connection.My network is as thus:
DSL Modem -> Wifi Router (Linksys E4200v1 - PPPoE enabled here) -> Gigabit switch -> 2nd Wifi router (D-Link DIR-815 - DHCP disabled, repeats same SSID and password)
Most devices are connected directly into the switch, with one computer hard-plugged into the DIR-815 (I will eventually change this, as the 815 only has 10/100 ports).Basically, I want to easily be able to check how much up/down data is being sent for my internet connection. This means that I cannot use a program on a computer (I've used DL Meter before. Works great, but limited to a single computer).
The Linksys E4200v1 is using standard firmware, but I'm not opposed to loading DD-WRT onto it (was the original plan anyway, just never got around to it), if DD-WRT has this capability.Nice to have feature: Ability to see which devices are consuming what part of the bandwidth. Not necessary, but would be a cool feature.Alternatively, if there is a cheap (like $100 or less deal) box that can interface, say, between the E4200 and the switch, that can do this, that would work as well.

What is the best way to monitor an Internet Edge router from the Internal network behind the Firewall?We want to pull more information from the edge router like netflow. We can use SNMPv3 and ACLs to keep the router secure.
But I am looking for the best config to keep both the router and firewall as secure as possible while still allowing us to monitor performance and faults.I am running an ASA and a 2821.

I am having a very strange issue with connecting new machines to reach the internet.We have a ASA 5505 which the previous tech configured the DHCP pool to 192.168.1.60 - 192.168.1.110
We ended up reaching our limit which I changed it to: 192.168.1.60 - 192.168.187
Then next day when I arrived to work, our DC was hung from windows updates. Once we got everything back up, every computer currently on the network can reach the internet/VPN tunnels etc. So (continuing with my day) I created a new server in a VM (Hyper-V)I can ping everything internally (even the router) 192.168.1.1, but I cannot resolve DNS. I have configured a static IP, tried Dynamic IP.I have looked for any ACL indicating to block outside the range of the old DHCP pool but no luck.On my local maching I can ping the DNS addresses, but just not on the new server.

Now I have a 172.16.0.0/16 network with a def. gw. for internet where is a MS Forefront TMG 2010 with BSplitter for traffic shaping. I purchased an 2921, 2,5 GB RAM, security+data license and an EHWIC-D-8ESG.
I made 4 subnets in a test environment with some access-lists, nothing fancy yet. How can I use FF TMG for bandwidth management, where should I put it? For those 4 subnets the def. gw. is, normally, the 2921 router. TMG is splitting traffic by client IP.

I have a 1TB internal SATA HD that I want to turn into a network drive. Since the MB in the desktop I had this drive in fried, I'm looking for options to network this drive (that stores photos, music, utilities, etc). So far after brief research, looks like my most reliable option would be an external enclosure with USB and a router with a USB share port.
-what other options do I have?
-what would be a good wireless N/G router with a USB share port, great range or range extender option and can handle multiple devices online (xbox, ps3, wii, droid phones, 2x or more laptops, wifi Tv all not connected at once, but a few can be, so I need a router to handle the demand)
-a good reliable external enclosure
I need a router that has a good strong signal. The current G router I have (d-link di-524(?)) works ok, but the signal cuts out in the kitchen and virtually non-existent in my garage (to use Pandora on phone).

When i check the status of my Internet Connection I notice that the sent and received bytes keeps increasing. I'm sure there are no downloads taking place that I'm aware of. No torrent clients, no antivirus nothing. I checked my PC for malware but that didn't work. As a result of this, i keep getting high pings in online games and can't even watch videos in youtube anymore. like, some software to monitor all the programs that use the itnernet connection without my knowledge or something??My primary concern is gaming (Call of Duty 4) so I wouldn't mind this idle downloading (whatever it is) as long as the major chunk of my internet connection is directed towards Cod4!

This has been happening of late. When i check the status of my connection, i notice that the "sent" and "received" bytes keeps on increasing when i'm idle. I'm pretty much sure there's no downloading of any sort in progress that I'm aware of. As a result of this, I can't watch videos in Youtube or play online games due to high ping.

[code] just came out with a new package called Roadrunner Broadband Extreme ($10 extra). The claimed speeds are 30GB down and 5GB up. I have a friend in another area of town who is getting these speeds consistently, although i will admit he lives in a much more "technologically advanced" area where there are several big technology businesses like IBM. I just had the service installed last week, and have even had the cable techs to the house, but i am not even close to getting what i paid for.On average a normal day i would test at between 14-17GB down and maybe 2.2 up (using Time Warner's speed test, on tests from places like Speakeasy the speeds show much lower).So the question after the long winded description is this. Is there any program i can use that may be able to safely tweak my system and get closer to the speeds i should be getting? I know i may never reach 30 down and 5 up, but if i could at least be in the 20's down and maybe 3.5-4 up.

We have ASA5510s and I've configured an SSL VPN using AnyConnect.. The VPN address pool is 10.10.10.0/24 and our internal network is 10.10.20..0/24. After successful login, using LDAP. the client receives a 10.10.10.0/24 address from the pool, but cannot access anything on the internal 10.10.20.0/24 network. I've toyed with access lists and NAT exemption, but to no avail. What do I need to do?

I have a small request. I have a setup where the internal users within the corporate network need to remote VPN into the VPN concentrator.
The setup is as below
inside
(202.x.x.x)VPN ASA 5520 ---------------- FW ------------- intenal network
----------------
outside
The problem is that the 10.0.0.0/8 internetl network establishes the connection via the outside interface. However, the return path is via the inside interface. But the vpn concentrator keeps showing next-hop not reachable for USP 500. Why does it show that when it has a route via the inside interface.
6|Jan 29 2013 13:44:38|110003: Routing failed to locate next hop for udp from NP Identity Ifc:202.x.x.x..29/62465 to outside:10.163..x.x/5892
Also, since we are trying to send traffic from outside to the inside interface, I tried to NAT the source ip i.e 202.x.x.x and left the source unaltered. But it still doesnt work.
I am wondering why is the ASA not routing via the inside interface and looks for the return traffic via the same outside interface the traffic entered in. The outside has a security-level of 0 and the isnide has a sec-level of 100.

I was wondering if there is a way to monitor the total bandwidth available at any given time? My ISP claims and is charging me for a certain amount of bandwidth but I suspect that during the day I am getting much less.
I would like to track available bandwidth continuously (or every 5, 10, 15 minutes) and log that data so I can show them the results. I'm on a Mac 10.7 but can use Windows XP also.

-Taking all of the bandwidth.
-My computer is causing it.
-Our Internet providers are Comcast(cable) for default and Frontier(DSL) for backup; business class.
-Normal: 6Mbps down, 4Mbps up; Abnormal: 0.4Mbps down, 0.2 up; around those numbers.
-Possibly a virus.
-Task-manager shows as much internet use as usual, even if it is apparent that my computer is using allot during that time.
-Random times.
-Might have settings allowing it to take however much broadband it wants, I do not know if there is such a setting or not.I only have a day or so before my dad cuts me from the internet.

I'm not sure about my title, it;'s the best I could come up with. I have approximately 7 computers, two iPhone, and iPad, wireless printers and a network attached storage. Most are connected over via wifi, the exceptions being one pc, the nas and a printer. I plan to add six more devices plus some ip cams. The way the router or network is configured whenever a guest connects to our wifi they can "see" our computers. I haven't been able to tell if they can see the files or just the name of the computer. Question 1: How can I tell if the guests are able to access the data on our computers or networked drive? Question 2: If I add a switch will I need to do anything special with regard to security?
