I have a branch office connected to the Head Office through a VPN Tunnel in cisco 1841 Router. If i enable Internet for any pc in Branch Office through cisco router i cannot access it remotely from Head Office. [code]
View 2 RepliesI 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.
Below is the current running config:

View 3 Replies View RelatedI 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 ?
The situation is I have a windows 2008 server with two nics, connected to two routers. The routers are connected together as well. This diagram might explain further:[url]....
Each router effectively defines a completely different network. The server nic connected to the internet facing router is configured with minimal properties (no ip6, no file sharing, no netBIOS over tcp etc), the nic connected to the internal router has mostly default properties. Both nics have static ip addresses. Both networks define a subnet of 255.255.255.0. The nics are not bridged in the server and it is not acting as a router or anything network related.
The problem is I cannot access the server when both nics are enabled. If I disable the nic for the internet facing router, then everything is fine. If I establish a connection to the server such as through remote desktop, then re-enable the nic it still works but I can't ping or make new connections.
Today i received FWSM from cisco (RMA), I need to configure it as standby unit for existing FWSM active/standby setup.
IOS on RMAed FWSM is 2.3.4 and cisco VSS supports FWSM IOS 4.0.4 and later.My issue is, I cannot access FWSM (IOS 2.3.4) via session command from cisco 6513 but could successfully consoled it without any problem. I have reloaded it twice and also tried to disable and enable power on it.

why I cannot access FWSM through session command ?Whether this is because of older IOS ? If yes then how to upgrade its IOS ?Is it possible to upgrade IOS via FWSM console ? if yes, Do i need to test on different slot ?
I have windows 7 PC. On the normal bases it has 3 internet connections 2 wireless and 1 hardwired. The 2 wireless are used for internet access and the hardwired is for my LAN through my router. The wireless connections are throught ATT mobile devices. I use my lan to share files through PC in my household and it has no internet access. The problem is that whenever I have all 3 of these connections connected windows always sees the hardwire connection as internet access so I can't use the internet even if my 2 other wireless connections are enabled. However, If I disable the Local area network connections and the leave 2 wireless connections enabled I have internet again.is there a way to just make windows use the hardwired connection as local and use the wireless connections for internet?

View 5 Replies View Relatedi have come across this solution to dual internet connections, c2950-i6k2l2q4-mz.121-22.EA14.bin is the IOS and the router is a 2950 Dual Wan model. I don't know alot about this stuff I'll admit, but it is on the default configuration with IP 192.168.27.7 255.255.255.0, gateway at 192.168.27.8. The hostname below is something I don't know exactly what it means but my guess is its the line at the command prompt with the name.
It has VLAN1 with fa0/1-24, gi0/1 - 2.
This is the script but I don't know why its not taking the commands as at ip sla monitor 1 I get invalid command error. What do the ! mean are they comments and not entered?
I have a laptop that is running windows 7 premium and a desk top that is running xp pro. The laptop is connected to the internet but the desktop is not. I have them set up in a ethernet network through an RJ-45, and both are connected, but I can't seem to share the laptop's internet connection with the desk top. I've enabled internet sharing with the wireless network, but my desktop still cannot connect.
View 1 Replies View RelatedOk, so I recently upgraded to a Linksys E3200. I am trying to get the QoS to work properly. I know that it is supposed to prioritize network traffic, so that if I have busy traffic but I am playing an online game, it should keep my gaming from stuttering while slowing other traffic down.
The problem is that every time I enable QoS everything slows down dramatically. I had a 200MB download that was going to take 5hrs with QoS enabled, that took 10min with QoS disabled. And with QoS enabled I can't even watch a youtube video without it pausing to buffer every 10 seconds. And that was the only PC/device using the network at the time. Again turning off the QoS WMM option solved the problem. I have noticed this problem with multiple routers and brands and usually just disable QoS as soon as I set up a router, however I heard that I won't get the full benefit of 300Mbps without QoS enabled.
I don't have any special Voice over IP needs, or video streaming etc. and I rarely am using multiple network devices at the same time. Is there really any reason I should enable QoS? Also I never really play with the settings for QoS, I just figure that since it comes enabled by default it should work for the average consumer.
I have both the WRT54G and a E1000 wireless routers and this problem is occurring for both of them.I use AT&T DSL and the speeds are fine when it is :
1. Not plugged into router
2. Wireless Network Mode is disabled through the router configuration page, having all devices wired.
However when wireless network mode is enabled, speeds drop significantly, 15~17 ms ping goes to 250~800 ping, and download speeds are way lower also. When the router is reset, the regular speeds will return for maybe 30 seconds to 1 minute, then it'll drop back down. I'm positive there's no outsiders connected to my network and this problem still occurs, only when the router is giving out wireless signals. Sometimes the problem randomly goes away for a while but it will always come back. I've tried many things, firmware upgrades, factory restore, none of them seem to work, the only solution so far has been to disabling it, but I need it to be on as there are other devices in other rooms of the house that need WiFi to connect to the internet.
E3200 works great until I enable QoS. The device uses QoS and works find until reboot. If QoS is enabled and the device is rebooted, its stops routing from LAN side to Internet side. Administration-->Diagnostics allow me to ping/trace route to Internet sites and local LAN clients but cannot reach Internet from local LAN.
Windows networking icon indicates "No Internet access". I can ping other devices on local LAN.
Disabling QoS restores routing and you can re-enable QoS after that and all is well. Unfortunately, if there is a power failure when I', not there to disable/re-enable QoS afterward, other household members can't use the Internet till I get home.
Wondering if any other QoS users have observed the same problem.
I have new DIA Internet service coming in and unlike the last vendor who provided a router, I am configuring my own. This is my first full Cisco config - I've been looking at this for 3 days now. I have SIP signalling, rtp and default traffic on a (3) t1 multilink (4.5mb). My lan and firewall uses dscp tags and passes them to the 1841 for outbound. The ISP only prioritizes by destination address so I just need the 1841 to respect the tags internally. Inbound, I have only port numbers to go by to differentiate voice traffic and I want to tag EF and CS3 accordingly for use by the 1841 and the rest of my network.
Below is part of my proposed config. I have read tons of Cisco docs and looked at all the queuing methods and this one I understand the best. I am getting the error: "CBWFQ : Can be enabled as an output feature only", so I presume that something is wrong on an input definition somewhere. For now all the firewall functions are done at the actual firewall (Sonicwall NSA) so other than limiting ports to the PBX everything else is just pass-through. Any changes required. IOS is 12.4(4)T1.

I was able to configure the cisco to accept VPN connections from clients. But when i am connected i can not access the VPN LAN. My cisco VPN client shows all the time Packet Decrypted: 0 when connected. I tried the split tunneling configuration based on the example on cisco.com for split tunneling.

I have a 1841 router with two wan access from two different ISP:throught dialer with fixed ip obtained from dhcp - ATM interface,thought fastethernet 0/1 with fixed ip and a specific gateway - can be use for Internet traffic if dialer is down.I can't manage to make them accessible at the same time (ping and ssh).In a second time I would like to have a VPN client access on one wan and site to site VPN on the other, instead of having the two on one wan.
View 12 Replies View RelatedI'm working on setting up a couple of new WAN sites with 256K frame relay circuits back to our main building. Each new site has a new PVC, and both are pointing back to a PVC on a T1 at the main building. The main site has a 2801 with a single CSU/DSU WIC, and each new site has a 1841 with a 3560 connected to fa0/1. At both sites, I'm able to get the circuit up, and the serial interfaces at both new sites show up/up, and the subinterfaces at the main site also show up/up for both sites. Routing is being done by EIGRP, and both sites are able to establish the 2801 as an EIGRP neighbor, and I'm able to ping/tracert anywhere on our network by name or IP, so routing and DNS appear to be working. I can also ping both new routers from the main site. However, that's about all I can do. I'm not able to access any resources on our network (email/shares/internet/intranet/etc) from the two new sites. I can ping the new routers/switches from the main site, but can't ssh to them. I can ssh to them locally. There are no firewalls in the equation, and I don't think there are any ACL's in the picture either.
Can ping and tracert just fine anywhere on our network (from both the 1841, a PC plugged into the 3560, or a PC plugged directly into the fa0/1 port on the 1841), including out to the internet, by name or ip.Can ssh to local router, but not to anything that isn't localDNS is workingDHCP not working using ip helper pointing to DHCP scope on server at main site, have to use static IPCan't rdp to anythingCan't get emailCan't browse windows sharesCan't get to any websites, external or intranet. IE says "Website found, waiting for reply..." but eventually times out.
I did some testing for communication over certain port numbers using telnet and nmap, and found the following:
Can telnet to url.. and local intranet webserver on port 80 (http)Can telnet to two of our Exchange Servers on port 25 (SMTP)If I run an nmap scan on url...com, or our intranet webserver, it confirms that 80 and 443 are open, but the pages will not load. I am able to telnet (port 23) to a state mainframe via the internet that some of our employees use, and I do get the expected login screen. I tried erasing the config one of the new routers, and just added back the bare minimum config to get the circuits up (serial/ethernet interface configs, eigrp), but saw the same symptoms.
One other thing to note: the 2801 at the main site has three other frame relay sites connected to it on the same WIC as the new sites, all of which are working fine.
I just don't understand why I can ping everywhere I need to be able to ping, and port scans show that communication is open over needed ports, but the applications don't work.
I have setup a remote access on our 1841 device, with split tunnel.
now i am able to connect via the vpn tunnel, and even ping and telnet into the cisco device, but when i try to ping any device past the 1841, the ping fails and no traffic is even been encrypted to go over the vpn traffic (looking at the vpn client statistics).
From the ciscos side, pings to the vpn client is failing, yet i see the vpn client in the routing table.

View 1 Replies View RelatedI have an 1841 between my firewall and the ISP. Three interfaces - multilink to ISP, FA to my firewall, and FA to my inside network. I use the inside interface for configs aand snmp access, etc. Only my ISP-assigned fixed address block will get routed to the multilink by the ISP but I am nervous about the inside interface sitting on my LAN. I know I can remove it, but if I keep it there, how can I set up an ACL so that all traffic from the multilink interface is denied to the inside interface? I suppose another way to think about it that the inbound iface can only accept traffic from its own outside, not from the router.I think this is fairly simple but I don't want to knock down the traffic if I get it wrong.

I am not getting any hit on the deny statement of 102 when i try pinging to client ip address (10.0.0.10).
configured Ezvpn Server/client with client mode configuration on IOS router with ver advipservicesk9-mz.124-15.T3.bin of ISR 1841 routers. Only my main issue is that once the tunnel is up I cant access the server side local LAN. However I could each site my icmp traffic is encrypt or decrypt but not both at the same time. However I can ping from the server to the client ip address which is assigned by the pool (int loopback10000)
Also once the tunnel is up I could also see there's static route towards the client side via virtual-access interface and also static route on client side. I have already configure SPLIT ACL on server side allowing the required network access.Attached is the configuration of both server and client with all required show output.
I can ping across the tunnel from the pc's on either end of the tunnel, but I can't ping across the tunnel from the routers. If i ping using the source command using the LAN interface, the ping is successfull.
The reason i need this is for the remote router to be able to lookup the head office server for dns wins and ldap.

View 4 Replies View RelatedI have a 1841 deployed as my NAT device towards internet. NAT is setup so that internal addresses can access WWW. I also have some NAT translations opening speciic ports from outside to inside in the form: ip nat inside source static tcp A.B.C.D 443 A.B.C.D 443 extendable.
Now have an outside address/port setup with a public DNS reference and using NAT from outside to get access to the corresponding inside address. It works when being outside the LAN.
Now to the problem: From the LAN side of the router - i cannot access the public name. I can ping it - but my browser dont find the webserver behind the name. Someone told me it should be setup as "local firewall domain" - and i should set this up as "source NAT".
I have restricted access to users using TCP/IP using cisco 1841 router in my organization.
I need to permit some sites for users which are part of work..
The issue here is I cannot ping to the site but able to browse to that site when having internet access, i have permitted range the entire range of that IP's but still no luck..
url...is the site which is not pinging from internet.I have also checked the source code for the root IP but still no luck.
I need to allow only a few Internet websites from Cisco 1841 Router for my LAN users. What Access-List should be used for this.
