Cisco Firewall :: Pix 515e V 6.3 Throughput Speed To Time Warner?

Aug 23, 2011

I have a Cisco PIx firewall that is connected to a cable modem with Time warner cable. I am supposed to have 35 down and 5 up for my speed on that modem. When I bypass the firewall and connect directly to the cable modem, I get download speeds in excess of 30 and upload speeds of about 5. However, when I connect via my workstation, which goes through the PIX, I am lucky to get speeds in the 1.2 for a download and 2-3.5 for the upload. I am using a laptop to test. We have gigabyte Cat5e cabling and gigabyte switches.

Below are statements from the config.The interface lines are per below:
 
interface ethernet0 100full
interface ethernet1 100full
interface ethernet2 auto shutdown
 MTU outside 1500
 
How can i adjust this so I can make use of the 30 speed of the modem?

Cisco Firewall :: PIX 515e 2 ISPs Max Speed Is Slower With ISP

Apr 19, 2012

have a PIC 515e connected to two ISPs via 2 interfaces.  ISP1 is a 3.5Mbps aDSL line, and ISP2 is a 30Mbps business cable.  I've confirmed the speeds by connecting the cabled directly into a laptop and using wget to download very large files from known-fast sites.
 
For admin reasons, I need to access two specific subnets using the slower ISP1.  The rest of internet traffic should go to the much faster ISP2.
 
So I configure ISP2 as the default gateway, static routes for the two subnets to ISP1, set up NAT (PAT) and it all works like a charm.  I've confirmed that ISP1 is used for only the two subnets, and ISP2 for everything else.  CAPTUREs on the pix also confirm this.  So far, it all works great.
 
But for reasons I don't understand, my max. download speed is 3.5 Mbps (the slow DSL).  Using various speed tests and wget, I simply cannot get a download speed faster than my 3.5 Mbps DSL line.
 
 
Here is my config:
interface ethernet0 100full
interface ethernet1 100full
interface ethernet2 100full

Linksys Wireless Router :: WRT54GS And RCA DCM 425 Time Warner Disconnections?

Jul 6, 2012

I have a 2 computer connected to the WRT54GS which is connected to the RCA DCM 425. It was initially  fine, however now the internet is disconnecting at an absurd rate, at least 3 within an hr, sometimes more, and the only way it would reestablish connection is by unplugging and replugging.I have called time warner's customer support  and they said it was because of the router. I have searched through various threads and saw and some had similar problems, but they were related to wireless instead of wired ( my case) so is there some settings i can change within the linksys to minimize the amount of disconnections? Becaused based on the log from the RCA,it seems that they are not reading  each other too well. Are there any other routers that may establish a connection better than the GS?

Belkin Routers :: N450 - Hardwired Time Warner Speeds

Without my N 450 router hooked up I am getting hardwired speeds of 50/5 mb, but with N 450 hardwired into my PC the speeds drop to 20/5 mb. I have checked DHCP and I am not getting piggy backed. Is it a bottlekneck, misconfigured or just not compatible with Time Warner?

Cisco Firewall :: Upgrade From 5505 To 5520 On Network - ASA Firewall Throughput

Feb 27, 2013

I'd like to see some REAL LIFE comparisons of ASA firewall throughput (a bit like this one for ISR G2 Routers - [URL].
 
The reason I ask is that I recently upgraded a firewall from an ASA5505 to an ASA5520 on a small network where the only outside connectivity was a single 10meg Internet circuit with an IPSEC VPN (not landed on the firewall but on a router) to another site.
 
When I swapped out the firewall the users noticed a big improvement. The firewall is not doing anything out of the ordinary - no IPS or VPN, just standard state full inspection.

Cisco Firewall :: PIX 515e MAC To IP?

Oct 6, 2012

I have the following network.2 WAN links termination on my PIX 515e and all internal users connected to third interface.
 
Problem I am facing is that I have assign manual IP to users with some have full access to Internet while others have limited.
 
The users are changing their IP address while others are offline and I want to restrict them.
 
The only way I can think off is by binding IP to MAC as e.g ( Active wall software). But can it be done on PIX 515e and if so how?

Cisco Firewall :: Only 30Mb/s Throughput On 881?

Mar 31, 2011

I have a Cisco 881 (without wifi model) connected to a 100Mb unmanaged switch and a cable modem with a 120Mb down, 10Mb up connection. When I connect the modem directly to my laptop, I can reach the 120Mb/s down and 10Mb/s upload speed. When I connect the modem to the 881, the max download is about 30Mb/s. Upstream 10Mb is no problem. I've been trying to change the duplex and speed settings on the FastEthernet4 interface, but this has only a worsening effect. I should be able to get about 100Mb/s (since switch is only 100) right?

Download Speed Varies On Two Systems At Same Time

Feb 19, 2012

I am using my normal Ethernet cable that I used on my old PC at the exact same location / circumstances, but when I plug the cable in my new PC, my download speed peaks at 81.5 kb/s and my upload speed peaks at 10 kb/s. Now when I put it back in my old pc I get 3mb/s download speed and 0.5 mb/s upload speed. I don't quite understand what the problem is. Do I need to update drivers/BIOS? I can't find any updates. This is a clean install of Windows 7 Ultimate 64 Bit with barely any programs installed as of yet. I have reinstalled Windows 7 aswell, to no avail.

Download Speed Degradation Over Time - SBN WR11N R2 Or ISP?

Mar 20, 2012

I'm having issues with my download speed lately and I need to know whether it's my router that's causing the problem or my ISP.When I leave the router on for a couple of days, without rebooting it, my download speed degrades to about 40-50% of what it usually is and when I reboot it the speed is back to normal.It's a 150Mbps Wireless N router, model SBN WR11N R2. I have no idea what brand it is, my ISP gave it to me a few years ago. Seems to be running some custom firmware installed by the ISP.
