I have Cisco 871 acting as a VPN server behind another router in the same LAN. The problem is that I can't connect to the VPN from outside network using the public IP but I CAN connect to the VPN from inside the LAN using the internal IP. I've assigned a virtual server on the main router to forward the traffic (port 1723 and 47) to the VPN router but still doesn't work.
View 2 RepliesI have a 6506-E with 720 Sup. I am trying to connect a server with HP 550SFP Nic to my 6506.If I plug the SFP from my server into my 6506 it will not link. When I plug that very same SFP into a 3750 it links fine. Makes me think that there is something I am doing worng on the 6506 Config.But, If I plug another server using a IBM LAN Card into the same port on my 6506 it connects and works fine so now I am starting to wonder.

We want to connect server to switch through FC cable and both switch have SPF module. But when we connect server to switch, link do not establish even switch and server port light become off.
Then we have tested the following things:
1. Connect server to server through FC cable, it is okay.
2. Connect switch to switch through same FC cable, it is okay.
I don't understand why it is not working.

View 2 Replies View Relatedabout three months ago I set our 1751 router as the NTP server of our domain for both our AVVID phone system and our Microsoft Active Directory domain. Been working excellent up until last night. Our company's building had a power cycle and the router got rebooted. Not a huge issue, since it's actually been rebooted a couple of times since becoming the ntp server.
After it's reboot, the time somehow jumped ahead an hour according to all the devices that sync with it. Phone calls stopped working and Active Directory pretty much became useless.
I finally had to break all the devices off of syncing with the router and set them back to the way they were (phone servers sync with each other, active directory doesn't sync with anything externally). It took a few hours to get everything stable again, and I'm still working on parts this morning.
Here's what I've had setup now for three months, we're in Central Standard Time:
ntp clock-period 17179971
ntp master
ntp server 69.26.112.120
and I set the "clock timezone CDT -6" It's been like that for three months and everything was fine till last night when it went out of wack.

I am running into a DHCP problem on a Cisco 891 running 15.0(1)M2. I am running DHCP on the router and want to reserve an address for a printer. I have done this hundreds of times on hundreds of routers. Per Cisco recommendation, I let the printer lease an address to see whether it uses it's "hardware-address" or "client-id". This printer uses the "hardware-address" format. The printer has leased 10.0.0.102 right off the bat. I want it at 10.0.0.50.
I have a DHCP pool, like this:
ip dhcp pool CLIENT
network 10.0.0.0 255.255.255.0
domain-name chsinc.ds
default-router 10.0.0.1
dns-server 10.0.0.1
lease 2
I create a "reservation" like so:
ip dhcp pool HP_LaserJet_Printer
host 10.0.0.50 255.255.255.0
hardware abcd.ef12.3456
Now I do a "show running-config" to see what I've put in and it looks just like above. Now we reset the network settings or change any network setting on the printer to force it to renew it's lease. What should happen and what usually happens is that the printer should request an IP, be offered 10.0.0.50, accept that IP and come up on that IP address. What is happening with this particular printer is that the printer requests a specific IP (the same IP that it had initially = 10.0.0.102), the router says OK and does not enforce the reservation. Then the router actually deletes the hardware-address config line right out of the running config. A "show running-config" shows that the reservation config now looks like this:
ip dhcp pool HP_LaserJet_Printer
host 10.0.0.50 255.255.255.0
See the logs below. Notice the ones in bold.

Is there a way to make the router enforce the reservation and not let clients just bring their own IP and actually make changes to the running-config of the router?
I have a 3911 router with a 1242 AP. The problem that I have is that when the user is trying to connect, the user get the OS Ip address 169.254.168.154 and I see that when I do the "show dot11 association" command, but when I do sh ip dhcp binding on the router I see

The router is seeing as if the router gave the ip address to the user, but the reality the user was assigne the OS ip address 169. I did "debug ip dhcp server events" and I got the following:

I'm trying to view the logs from a Cisco 857W router to a workstation running the Kiwi Syslog server. what I've done is the following:
Config term
Logging on
Logging source-interface BVI1
Logging Facility Local7 (or any other facility you want to allocate for this router.)
Logging [IP Address or Hostname of machine running Kiwi Syslog Server]

I see noting on the syslog server. Although I can see the log information on the router Also is there a command to stop the logging from generating or is this on by default.
I am using Solawinds syslog and trying to get our Cisco routers send syslogs to our syslog server. I followed the procedure on Configuring Cisco Devices to Use a Syslog Server from [URL] Our Cisco swtches are all sending syslog messages but not the routers. I compared the config with our access switches but can't seem to find the problem:

View 2 Replies View RelatedI am with Virgin media and have a home lab (2611 routers, 3550 switches, 2950s etc) which i usually just use for testing things on and practicing.
Now I tried to connect it to the internet and got some weird things happening.
I got NAT and DHCP client all setup correctly on the router (or so I think!) along with DNS settings but I still can't get Internet access.
My network is all setup right so that through using OSPF the router is the gateway (0.0.0.0 route) for all devices. Doing a traceroute confirms this.
Yet I never get any further than the router? I see IP nat translations ticking up as I send more requests but never get a webpage or a reply from any of the machines in my network.
HOWEVER... The router itself does get some replies from Google.co.uk and bbc.co.uk but doesn't seem to want to give anything else on the "inside" a response?

I have and 880 W router. The LAN members can get out t o the internet. Now I want to configure NAT such that outside computers can access a couple of the machines using Remote Desktop (RDP). I am using Configuration Professional.
When I configure inside to outside, the remote computers can't connect to the target machines.When I configure outside to inside, the target machines acn't get to the internet.
When I try to use the advanced NAT definition wizard, I can't complete the task because the only inside pool (?) or LAN (?) is "designated" and not available to select. I can't free it up without deleting the one working NAT entry which is the one that enables all computers to reach the internet.

The 871 is setup as a VPN Server. now when clients connect to the VPN they can ping the VLan IP Address on the 871, but they can t ping any other hosts on the smae network. The hosts on the private network can ping the vlan on the 871.
View 7 Replies View RelatedI was so fed up of using the out of a box routers from PC World or the provided router from the host that I decided to splash out and buy a decent router.The Cisco 887 came highly recommended and seems to be a great purchase so far. Our down time and internet hangs vanished overnight.Having had this installed for several weeks now I thought it was time to look at my problems with it,I have 2 broadcom network cards, 1 for the LAN and 1 for the WAN, All machines connected to the LAN get full internet access but my server will not.
The router plugs directly into the Server (2008) with an IP address of 10.10.10.1 - this is listed under the LAN settings in Cisco CP Express.I have a fixed IP address which appears to be set up correctly and all my terminals / client pc's that are plugged through the switch. These all show IP's that look like 192.168.1.x / I am not an IT wizz kid but I know my way around a computer pretty well. I am guessing I need to move the router IP to within range. At present the Server sorts out the DHCP and we also have a VOIP phone system.
On our ISA server we have some publishing rules with the option "Requests appear to come from the ISA Server computer". This allows us to forward incoming external traffic to a network that is not directly connected to the ISA Server internal interface. We need this because our internal server does not know the route to the internet client but does know the route to our ISA Server, so the internal server sends his response to the ISA server and he sends it to the internet client.
