Why in some places I can not switch on my VPN ? The strange thing is when I use the VPN server of my office , this work OK and it is the same VPN client. So this means that I do something wrong in my private CISCO 1841 ROUTER.Here bellow what does not work and at the bottom the same computer same network.

I have a Cisco 2940 switch and a Cisco 1841 router. I want to build two different VLAN networks on the switch, which do not have to communicate one with each other, but those VLANS should communicate with the router.
I read a lot of articles, i tried to configure properly the switch and the router but i still don't get them work.
I set on the switch, the GigabitEthernet 0/1 port to Trunk port and i had to set it a native VLAN. The problem is that only from that native VLAN, i can ping the router.
We have a cisco 1941 with line t1 Symmetric, (Also have Cisco 1841 unused, but works) I would like to connect the Cisco 1841 to four Adsl Backup lines in case the T1 or the Main cisco 1941 go down I know a BGP is needed on our ISP site,
How can i connect four Adsl lines to The cisco 1841 (Backup) and make them work in a Load Balancing way.
I'm trying to configure my BRI interface in "network protocol-emulate network" and "layer1-emulate network" but i don't have this second command.Is someone have allready to that with this type of interface ?I've to configure this because the ISDN line of my telco is in user mode only.

View 2 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 got a cisco 1841 router. I am able to create different vlan in the cisco router and I have got only 2 ports, fa0/0 and fa0/1. Now, I need to create different network in the same router at least four networks. FA0/0 is used for external networks. Now I want to create 4 vlan in this router. Namely, 10. 10. 10.1, 10.10.11.1, 10.10.12.1 and 10.10.13.1. The FA0/1 is connected to a 48 port normal switch. In the switch I am going to connect the cable of all the 10. 10. networks. Is this possible to access creating four vlan and routing all of them to the external networks with the fa0/1 port only. Is dot1q possible with only the router and a normal switch or is there any other possibility for this case.

How to configure static nat on cisco 1841 so static nat will work and address will be translated in different IP when connection trough VPN.
I have address 192.168.235.1 and I want to translate to 192.168.100.1?This 1841 is border router, and all VLNAs and VLANs routing is on 3650.
I work at a small public library and we're trying to setup wireless internet for our patrons. I've been studying VLANs, trunking, etc and going through the Mike Meyers book trying to study and learn enough to prepare for the Network+ cert. We are using a Cisco 1841 router, a Linksys SRW224G4 switch, and we just purchased on recommendation the Cisco WRVS4400N Wireless N VPN Router.

I am using 1841 LAN router. Recently some broadcast is happening in our network when some users are connected. I need to block them automatically by detecting who are they.
I can block them manually but i want router to detect them and block.
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 ?
I am try to setup my office network to able to connect to one of my customer HQ via site to site VPN. I am using Cisco 1841 router to do the job.
The problem that I am facing now is no able to connect my other PC in office to the remote site.

View 2 Replies View RelatedThe company I work for has a system that our employees clock in on called UNIX (ancient program). I have an iSSH app on my iPhone that I can now log in to as long as I am on our wireless network here at our office. However, I have to travel alot and usually I'm gone during the day that all our time corrections have to be adjusted and turned in. I just log into my Unix program and adjust it...however if I'm out of town I have to do the entire thing over the phone with a lady in our book keeping department and it's incredibly annoying and time consuming. So we're looking for a way to be able to access our system through my iSSH app while on cellular network rather than being here at the office. My administrator wants me to find this out so that all our department heads can do this. I don't have any way of getting our internet provider to set up a port forward, so the only information I have to work with is our static IP address, our default gateway, our subnet mask, and the primary and secondary dns servers.

View 4 Replies View RelatedAll wires terminate in the basement as a RJ-45 plug, to be plugged into a switch housed in an old circuit breaker box. The first wire went off without a hitch, the jack works, the plug works, all is right with the world. The router for the home is currently plugged into that outlet so as to give the entire network as we build it internet. The second outlet is giving us problems though. I've fished the wire up the wall as before, and the length of wire is shorter than the first run. When I terminate the end upstairs as a jack, then plug in my laptop, it refuses to connect. It says the network cable is unplugged. If I terminate the cable as a plug, then plug it directly into the laptop, suddenly everything works. I have tried so far 3 different jacks, tested continuity on the jacks, and tested continuity on the wire to the jack pins to make sure the terminal block was working and everything came back green

View 19 Replies View RelatedI have two computers sharing files connected by a wired lan via an Ethernet card. Both are using XP home sp2 OS and neither of them had any Internet connection. I wanted to make one of them connect to a wireless printer so I added an Asus USB (wireless) dongle to that machine only.When first used the dongle sprang into life, connected to a wireless router in another part of the building (also mine, but nothing to do with this network) and downloaded a load of MS updates. Whilst an Internet connection was not really needed on that machine I thought 'all well and good', and proceeded to download MS Security Essentials onto that machine only. Once the printer software was installed on that computer it connected normally with the wireless printer and printed-out fine.It was only when I attempted to connect to the other computer via the hard-wired lan that I found that the connection between them was broken.
