Is there an easy way to allow specific websites access in cisco router 1841? I am trying to allow a website through access list 102 but not working. I am using access-list 102 permit ip host 192.168.21.20 host www.website.comIf i allow all websites then it works fine.
View 1 Replies View RelatedHere's my setup:
- Cisco 1841 connected to the internet on fa0/1
- LAN connected to fa0/0/1 (switch port, connected to Vlan1)
On my LAN I have a web server that houses different websites. Those websites have DNS records that point to my public IP address, located on fa0/1. From the outside I can reach the websites perfectly, but I can't reach them from the inside. So it looks like I can't seem to connect from my local LAN address to the public ip address on the Cisco (who then should NAT it to the correct server)
Here is a snippet from my config:
--NAT--
ip nat inside source static tcp 192.168.0.3 80 interface FastEthernet0/1 80
ip nat inside source route-map Internet interface FastEthernet0/1 overload

I loaded in Qwest wireless software for their internet and now I can not open half the pages I use to be able to.

- I can only access to Facebook, Spotify, but nothing else.
- It sometimes randomly comes back and everything works but then it only lasts for a few minutes-hours and it goes off and won't work again. I've tried resetting the modem, router, and I even tried creating a new network but nothing worked out so far.I currently own a mac and a windows 7 laptop.
url...Yesterday all of a sudden my computer wouldn't load up a lot of websites. A lot of my favorite sites to visit now for whatever reason only load to a certain point than stop. The first picture is from Steam, the second is from a browser. It doesn't matter the browser, because it doesn't load on any I've tested.

View 14 Replies View RelatedI've been having a really annoying issue with my computer not connecting to the internet wirelessly I start the computer, and a connection is there via my router for about 30secs-2mins. After this, I can't access any websites. The full five bars remain white and the router is still seen by the computer, but there is a small yellow exclamation sign in front of it, and a mouse-over says "no internet access". I can still access when wired to the router through a cable, so I thought it might be an issue with my wireless card, but wireless USB adapters don't make a difference, even when I've disabled the wireless card. My drivers are all up to date, and I've even tried a full reformat and reinstall of Windows 7, to no avail. Other devices (a couple of computers and phones) can connect to the router fine, and the network even tried a new router, with no success. I have experienced this immediately after the reinstall, before either firewall (I use ZoneAlarm Free) or AV (I use Avast! Free) were installed, and I'm completely stuck.

But once i upgraded it wouldn't allow me to connect. my other computers are able to but not my main one. My ISP told me to bring it in to the shop cause they said something was blocking my connection. I ran some basic things i saw on the internet. i am able to get to web pages through ip address but not through the [URL] type ones.

View 6 Replies View RelatedI have an SMC2804WBR router. It runs slowly and refuses to even load some web sites. If I unplug it for half an hour, it works fine for three or four minutes and then slows right down again. SMC support told me to reset and reconfigure the settings. I tried it twice. It made no difference at all. It works fine for a few minutes after it has been unplugged but then slows right down. I have the cable connection plugged into a PC running Windows 2000 and that is where I have the router plugged in as well. This is not the machine I use on a daily basis. I use a MacBook Pro via wireless. If I purchase a new router that says the operating system can be OS X or at least XP, can I configure it from the MacBook and will it still work with the PC running on Windows 2000? I was thinking of scrapping the SMC and getting a Linksys E1200-CA.

The Dell will connect to the internet and I can see it's working because some of my programs can use the internet to function but when I try to use the internet it just stops loading at 5 bars on IE but then stops. I have tried a system restore but this has not done anything and tried a different browser but the same thing has happend.
View 12 Replies View Related My company has a peer to peer network of 10 personal computers without a server. Operating systems from Windows XP to Vista. I've recently installed a Cisco RV120W Wireless-N VPN Firewall. It's configured in DHCP Server Mode with printers/copiers that have static IPs below the DHCP range.
I'm having a problem with certain stations being used for personal networking, shopping, etc. during business hours. Consequently I would like to limit internet access on these stations. However, some internet access is required because of online database software that's an integral part of our business. I've been reading in the Administration Guide about URL Blocking. Would it be possible to give static IPs to certain stations and then limit their internet access to 1 or 2 specific websites?
FYI, I've read about the Trusted Domains and Blocked Keywords but cannot quite understand how to parley this into the solution I need.
How does one configure the router so that Internet users can access internal company websites? The only thing that appears is the Cisco router login. Also I need to configure Terminal Services and its not on the list under Service.

View 11 Replies View RelatedI have a Cisco 1841 router that is connected to a switch. I have WAN/LAN configured on the router and the switch is handing out internal IP's. The issus that none of the client machines can access the Internet. From within the router console, I am able to ping external domain names, my ISP DNS servers.
Once the client machines picks up an IP they are unable to ping any external domain names or IP's and not even the ISP DNS servers, but they can ping the Cisco router IP. As a note I have tried my ISP DNS servers and as a test Google's DNS servers, but neither will allow access to the Internet.

I am in trouble with my cisco 1841 configuration.The "what I want to" schema: very external IP ( AAA.AAA.AAA.AAA ) in the internet cloud => | cisco 1841 external IP BBB.BBB.BBB.BBB | => internal computer IP CCC.CCC.CCC.CCC

Steps (this what I think should be done):
1. Find all packets from A by acl
2. Route finded packets throught cisco1841 directly to internal ip address
It should be easy but it doesn't.
I used the GRE tunnel site to site VPN with 2 cisco 1841 routers. Behind one of the router R1, I used cisco ASA 5510, now my vpn is connect between two routers, but from R2 other site cannot access to LAN behind the firewall. From R1, also cannot route to local network, from local network can access to R1, I think cause of NAT . So how to configure to route internal network from R1 & R2 with VPN.

Fa0/1 is conncted to the switch using a 192.168.3.0 /24 network. DHCP is correctly assaigning ip addresses to the switch.
I connected the Fa0/0 port to the wall and used the following command to obtain an ip on the Fa0/0 port: ip adress dhcp. I used the following route command: ip route dhcp. That didn't work so I used the ip route 0.0.0.0 0.0.0.0 Fa0/0.When I run the sh cdp neighbors command I see a multilayer switch that show me connected to the Ga2/26 port with ip:192.168.179.254.I also see that the default vlan is 200 and the voice vlan is 800.
A linksys router is about to let us access the internet. I am able to ping the 192.168.179.254 address from the 1841 router.What am I missing to connect to the internet.I forgot to mention that I successfully receive an ip from the wall. The latest ip I received was 192.168.179.100 /24.
i have router 1841 have 2 interface.i make routing between vlan by subinterface in router and in switch trunk but vlan 5 cannot access internet

I configure for our office site to site VPN project. Now I configured already Site to site vpn between ASA 5510 and 1841 router.
HQ LAN
Branch LAN 10.2.1.0/24 >>> ASA 5510>>>>> 1841 >>> INTERNET <<<<<< 1841 <<<<<< 10.30.3.0/24 ^^^^ Call Manager 2851
Now can access from Branch LAN to HQ LAN each other. I face the problems that are
1) In branch LAN , they can access HQ LAN & resource , but cannot access internet. I didn't configure NAT on PH Router
2) Can I access internet from BRANCH LAN through HQ LAN to INTERNET. Or Can I access Internet from Branch LAN from PH Router directly while access to VPN to HQ LAN ?
3) In Branch Site , hard phone cannot work but soft phone on PC can call to HQ. Hard phone IP are same in Remote Network (172.16.1.0/24 ) . Is it problem ? how can I configure separately ?
We have 2mbps leased line and have Cisco 1841 which is managed by our ISP. I have hooked up another 1841 (please find basic config below, it will get more complex lateron) Now when I connect my laptop I am able to browse Internet. But when I conect VOIP phone, it is not able to contact it's Hosted Server on Internet.
VOIP phone is Polycom SoundPoint 550 and I get URL call disabed message. If I try netgear Firewall everything seems to work.that the voip provider needs following ports UDP Range 16384 - 32766, TCP 5060 & UDP 5060. But in my config all outbound traffic is allowed. [code]
I want to know is it possible to check Internet speed directly in the cisco router thru any command or activating any service in the cisco router?.As it is seen most of the times internet speed offer by ISP is different as compared to clients.and Clients most oftenly not satisfied with internet speed The problem is that our ISP has given us 100MB leaased line.But when we deployed in production network the speed is same as DSL.We have reported this issue to ISP they then carried out Iperf test by connecting laptop directly with the ISP router.They have tested the speed and it shows about 94-96 Mbps and argu that it is up to the mark and there is problem at your side(i.e our internal network).Now our internal network has cisco 1841 router connected directly to ISP 3825 cisco router.Our router has minimum configuration as required to pass traffic out and in.Our internal 1841 router is connected to switch to which different clients are connected.We have performed some online tests using different speed checking websites and also perform real time tests by uploading and downloading files.The speed is much low as compared to 100Mbps and it is nearly or slightly higher then as DSL connection. how can we check internet speed in the specified scenario?Is there any command or service available in cisco router to check internet speed as we want to check ISP connection speed directly thru 1841 router?what about authenticity of online speed checking websites?Any specialize software/tool you recommend to check Internet speed in specified scenario?
