Cisco VPN :: Pix 515E - Replace With Another 3845 Router?
Nov 18, 2011
in my lab environment, I have a site-to-site VPN between a Pix515E and Cisco 3845 router, using AES-256/DH-5/SHA for isakmp and AES-256/SHA/PFS group5 for the site-to-site VPN, I can only push about 26Mbps IPSec traffics (tested with Iperf). CPU on the Pix515E is running at 96% utilization
Now if I replace the Pix515E with another Cisco 3845 router, I can push about 100bps. Why such a big difference between the data sheet and actual real world

I need to upgrade/ replace a Cisco 515 E firewall with a Cisco ASA. Not sure what model yet! The pix has about 80 lines of ACLs and I side and outside interfaces with No VPNs.. I was wondering of those lines of ACLs can be transferred over to ASA as is or there are things I need to watch for ?

Is there any physical or technical diferrences between PWR-3845 AC/2 and PWR-3845 AC? We are trying to order replacement parts and wondering if PWR-3845 AC is for one power supply and AC/2 means you get two with one order?

My home router is an aging D-Link DGL-4100 and I am looking to replace it.My max budget is ~$250 USD.
I use 2 Ubiquiti Unifi UAP-Pro APs in my home for WIFI access, so I have the WIFI aspect of my home network covered completely. All wiring in my home is either Cat5e or Cat6, my switch is a gigabit HP ProCurve 1810G-24, and my cable modem is a Motorola SB6120 (Comcast cable broadband). I have 7 IP cameras (security system), 4 streaming media players, several PCs, a server, and several other network connected devices. I am the only resident.
I am looking to maximize my WAN to LAN (& LAN to WAN) throughput while maintaining a very secure network. I also want the router to have reliable VPN. If it is a wireless router, I would most likely not utilize the WIFI feature, probably turning off the WIFI radios and just use the router functionality.
I don't have the time/patience to build a PFSense (or similar) box and learn the software, so am only considering an off-the-shelf solution. Yes I know that PFSense and Untangle are great, I simply don't have time to learn them presently or in the foreseeable future.So, which router for wired performance and security would you recommend?

We use a 3825 router to screen alot of the junk from the internet side or our firewall. Its worked well for the last 4 years buthas rebooted multiple times in the last month for no apparent reason.At this point I think I would prefer to replace it.Our current internet link is 100Mbps and this router handles that quite well. Is there an equivalent that I should replace it with, or should I just buy another 3825 ?One with an OOB management port would be nice.

I had an issue yesterday with no internet access on my desktop computer; the message said "Network cable unplugged" so I called AT&T tech support for assistance. I have 2 Dell computers; a desktop and a laptop which I use wirelessly in the house.After doing several things from disconnecting the router to try and determine if the problem was with my router or an ethernet cable AT&T determined a port on my router which is 6 years old could be going bad and recommended I replace my router.I contacted Linksys yesterday; spoke to tech support for my WRT54G router and was given 2 model recommendations. One was a Model E900 N300 and a more expensive model; an EA2700 N600. There is a price difference of $40.00 USD between the 2 models. I could probably get by with the E900 N300 for $49.99 but the guy at Linksys was putting the pressure on me to buy the more expensive one for $89.99. I told him I'd have to think about it.

I am in the process of trying to replace a modem/router,the switch does not work with the new modem/router although if I connect the modem/router directly to my computer it works fine,so its not a router issue.I suspect that the settings need to be changed in the switch to allow the new router to work ?

I have a Cisco 1921 to replace our current router which is constantly freezing. We have a couple inside servers, one is a web server and application server which needs to be RDP'd to by a couple of clients outside of our network. I cannot get this to work no matter what. I know it's not the server's setup as when I plug the network back into the old router, it works just fine.
All clients have access to the internet, and I can successfully ping/resolve hosts from both the router and a client computer connected. I cannot, however, rdp using neither our public IP, nor our hostname. The hostname does resolve to our ISP assigned IP, but the server cannot be contacted, leading me to belive this is a NAT issue.

I have a Cisco ASA5505 with Frontier ADSL. I broke into their crappy little modem and obtained the settings needed to replace their modem with a 2621 router with a WIC-1ADSL module. I have a static IP from Frontier which is on my ASA5505 and the Dialer interface on the 2621 gets its address from Frontier via DHCP. There are devices behind the ASA which I need access while in the field, IP Cameras, Seed Treater, etc., so I have Anyconnect running on the ASA and can access everything from my laptop, iPhone and iPad from whereever. The issue arises when my laptop is in house and communicating with my parent company and I try to make a cell phone call off the network extender. The call is choppy since there is no QoS and the data is strangling the voice. Since I have control over the 2621, I added another network and NAT it into Frontier without them knowing. I have since placed the network extender on this network as well as a WAP200 that is wide open for my customers when they are in the office. Doesn't fix the problem but...
I have now added Evertek Wireless internet with a static IP also but they use a reservation based on the MAC Address of my interface of the ASA. This plugs directly intot the ASA via ethernet (I would assume their antenna is just a wireless bridge). I set route tracking on the Evertek side and use the Frontier as a backup and all devices on my NAT network still funcion on Frontier DSL and all my nornal data traffic is out Evertek. The issue is that the Evertek Wireless is not very fast or reliable (today in during a snow storm, it could barely keep an internet connection). And I had a problem with Anyconnect using either connection. I got that working. But think that the "ip address x.x.x.x y.y.y.y dhcp setroute" on the Evertek side messed things up from a routing standpoint when I would connect from the outside on the Frontier side. For testing, I switched the tracking around and now the connection on the Frontier side does not work but that is besides the point.
Frontier is going to try out an ADSL/2 connection next week which brings up another issue; all Frontier connections come into my buidling on a single 4-pair wire so if they go down, all my internet except the Evertek goes down. I have a Raven Slingshot coming for installation shortly that cannot go down; it will provide RTK (sub-inch accuracy GPS) to my customers that have auto-steer and auto-shutoff capabilities in their tractors via cellular data modem. So, while they are planting their crops in the field, if my connection goes down, their tractor will not function.
I also had a Cisco UC320W but it died a few days after it went off warranty so I replaced it with a Dell Server running 3CX IP PBX that supports Cisco SPA525G2 and SPA501G IP Phones. There is a 3CX iPhone app that allows me to receive calls while in the field, it uses a proprietary tunnel that I have open on the ASA. With 4-pair coming into my building, I will be left with a single 1-pair for phones so I am considering a SIP provider instead.
Can/should I move the Evertek ethernet to the third ethernet interface on the 2621 and track the Frontier DSL against the Evertek (backup) on the 2621 side and use the ASA to track the ADSL/2 against the 2621? Should I acquire an 1841 (or some other device that suppports the HWIC) with a ADSL/2 card and use HSRP between the 2621 and 1841? Is that even possible?

I have a 2651 that has an adsl1-wic that I am using as my DSL router. I recently acquired a 2801 that I want to replace the 2651 with. I configured the 2801 the same way as the 2651 but on a reload I get the statement that says
Setup: New interface NVIO placed in shutdown state
When I do a show interface all of the interfaces show up except the NVIO and I don't have any connectivity to the outside world. I am using Nat since I have a /29 and using nat pool overload. What am I missing? I am running IPVOICEK9-M 12.4.25c on the 2651 and adventerprise 12.4.24.T on the 2801

install a new N600 Wireless Dual Band Gigabit ADSL2+ Modem Router - Model DGND3700, to replace a Thompson Speedtouch USB Modem.
PC Windows XP Home Premium Media addition - Main PC X2 Laptops Win7 & Vista - fully working on wireless no issues.
I have managed to get two laptops working wirelessly with no problems, my main problem is the master pc needs to be able to use this router as well, but I cannot get it to work via the Ethernet cable!! I can get to to the Routers config page, I have done the following:
unplugged and removed the speedtouch modem, the old dial up connection is still available on the pc along with the speedtouch software and driver, I left this in place just in case the pc needs to revert back to the speedtouch modem, if I am unable to resolve this issue.
I have set the ip address on the PC to static and input the relavent Subnet and Gateway I can ping the Routers address 192.168.0.1 even though I have reserved the PC's Mac address and IP Adress I am unable to get to the internet. I have tried setting up a new internet connection via windows wizard.
when i look into the nework connections section in windows the local area connection is 100mb and there seems to be another connection which looks like another internet connection this indicates I am connected however I still cannot get an actual google session running.

I am looking to replace my current WAG54GS Gateway with the EA6500. Problem is the new one does not have a built in ADSL2+ modem (I am in the UK and my ISP is Demon Internet). I therefore need to purchase a separate Modem to connect to the router.

I need to replace a dying Netgear FWAG114 wireless router, and the E4200 gets good reviews so I've been looking into it. I'm a software developer running 6 servers plus 3 laptops and 5+ other devices (iPad, Wii, Droid phones, BluRay...). I prefer to use a trusted PC list (enter MACs for all trusted devices) rather than WEP or WPA - is this available with the E4200?
I don't need VPN, but I do run a number of web servers, app servers and databases, so port forwarding is important - I notice the E4200 provides port range forwarding and single port forwarding - I assume this replaces the Rules and Services feature in Netgear - right?
Do you see any potential problems, given my needs, in using the E4200?

I own an HP Pavilion dv6 Notebook PC and recently purchased a Cisco E1500 to replace my aging WRTG54 wireless router. Since installation of the new router I keep getting dropped from my LAN and the internet with "connectivity issues" ... this only occurs on my notebook PC and not the other wireless devices I have in my home. I’ve done some searching on the internet and this seems to be a generic problem with the Broadcom 802.11b/g/n card the notebook uses. I have 2 questions:
1) Is there an easy way to adjust either the card or the router to deal with these issues and if not then
2) what is the best notebook card to replace the Broadcom with to assure these issues go away.

We have set up a site to site IPSEC VPN between a Pix 515E running 8.0 (4) and an 1841 using static IP addresses at both ends. We used CCP on the router and ASDM on the pix to build the initial tunnels. Now the site with the router is changing to a Dynamic IP address from the ISP so we have set up Dynamic DNS to update the dynamic IP address.
The problem we have is that ASDM will not allow us to set a domain as the peer address, it will only accept an IP address. We think the solution will be to remove the static Crypto Map and replace with a Dynamic Crypto map on the Pix side. Our questions are simply; is this the best solution? can we edit the original static list or is it better to delete and make a new dynamic crypto map? Is there a short cut to change the config in command line? This is a live network so just want to check before we make changes on live kit.

Region : Malaysia
Model : TD-W8968
Hardware Version : V1
Firmware Version : 0.6.0 1.1 v0005.0 Build 120926 Rel.27100n
ISP : TM
I am having difficulty setting up the W8968 to replace the router given by TM for the Unifi connection.I tried updating the firmware of the modem router and used quick setup to configure the device as a wireless router using PPPoE, but still couldn't connect to the internet using the WAN port.I noticed there was a guide for TD-W8960N to set up TM Unifi but the web interface is too different from the W8968 interface.

I am installing Cisco blank CF upgrades (double the capacity of the CF that came with the router) in Cisco 3845 routers and I cannot get the IOS to load.
Network security requires tftp be disabled, so I am limited to xmodem. Slow, but it works. I know the IOS download is good, because I can load it on the CF that came with the router.
I can install, format and read the new flash. But the download locks up and bombs about 1/3 of the way through.
Note: CF that came with the router was "C" so I used the format flash: command. The new flash reads the same as the old, except that there is no file IOS loaded.
I've never had an issue upgrading an IOS, but this is my first shot at installing on a new CF.

1841 & 3845 router. We send 30 GB data on 100 Mbps link. First time we use 3845 router for sending the data and 47 Min are required to complete the data, during this link utilization was 100%. After that we send same data through 1841 router & 46 Min are required for the same. Only difference in data transfer is CPU Utilization of 1841 router goes 30% & 5 % of 3845 router Can we use 1841 router instead of 3845 router ? .
