I have a remote site on a 2811 IOS 12.4(15). Interface FA 0/0 faces the ISP and is set for DHCP. What command can I run to see all of the information given out with the IP lease from the ISP? I need to find out what the IP address of the DNS servers are.
View 3 RepliesI own a Nanostation5 Loco, and I have a router behind it.I would like to add a DHCP Lease to that router and do a port forward to the router.I can not find the DHCP Lease option in Nanostation settings, but if I choose to see DHCP Leases in "Extra info" on main page I can see some MAC and IP addresses there.When it comes to port forwarding, I fill the form slots with info, and when I press OK to save it a pop-up comes saying "Please fill out this field", a field for another forward rule.

View 2 Replies View Relatedmy Laptop is about nine years old, HP Pavillion Pentium 4. I run Windows XP Home Edition Version 2002 SP3. I use a broadband card from Verizon that I just put in my USB (no router, etc) I'm getting a System Error Source DHCP Event ID 1002. When this happens, my computer, I believe, is going into sleep mode and I have to reboot the system. When I turn it back on and go back on the internet, all my websites that I was in are still there. The error says: The IP address lease 10.170.223.48 for the Network Card with Network address 2c3068c16ED1 has been denied by the DHCP Server 10.173.229.86 (The DHCP Server sent a DHCPNACK message)The DHCP Server Service did not extend the lease on your computer's IP address, so your computer temporarily lost its connection with the Network. I tried the ipconfig /release and ipconfig /renew. I tried going in services.msc and going under DHCP and keeping it automatic but stopping it. I called Verizon and I believe he refreshed my Network settings (I think I knew more about the topic than he did) He said it was my computer, whatever. I just tried the static IP but it didn't seem to take. I restarted and it jumped back to automatic. My last guess is it's something to do with the time frame of when it automatically obtains the address and when it expires. When I do the ipconfig /all it shows only a two hour time frame before it expires. Today I noticed that my computer shut down/sleepmode at the exact time the ipaddress was obtained. So, is there a way to increase this time between obtaining and expiring?
View 7 Replies View RelatedI've been having this issue for about 3 months now, off and on, never seemed to be predictable but started happening more and more, which prompted me to look into it.
Currently, the DSL Modem is configured in bridge mode with the ASA handling PPPoE. The WAN address is being assigned via DHCP. The ASA is running 8.2(1). The WAN interface will drop it's DHCP lease and will not renew it without power cycling the DSL modem. I did a little bit of googling and found mention of setting "dhcp-client client-id interface outside", specifically this was an issue pre 7.2(22), but doesn't seem to affect my situation. Originally, I had the MTU on the outside interface configured as 1500, changing it to 1492 has not resolved my issue either.
I've enabled PPPoE and DHCPC debugging and posted the results below when the event occurs, I'm thinking this is moreso a PPPoE issue than it is a DHCP/DHCP Lease issue as I am not seeing any debug messages from DHCPC.

I have several Cisco WAP4410N access points. They are configured to automatically obtain an IP address through DHCP. This works fine, but I've discovered when the DHCP lease expires, the access point doesn't renew it. It continues to use the same IP address but does not renew the lease. If I reboot the access point, it will renew the lease again.Is this a known issue with the WAP4410N? Is there any way to work around this, other than setting a static IP address or rebooting regularly?
View 9 Replies View RelatedIs there a way on the security appliance SA520 to remove someone from the DHCP lease client manually rather than setting the DHCP lease time to expire in less time like 4 hours or 2 hours. I was able to do this on other routers by highlighting the connected device and click remove. If not any recommendations on how to handle the device that are attached via DHCP and the person is no longer here, but the lease time is not up. I have set DHCP lease time to 4 hours.

View 1 Replies View Relatedmy RVS4000 is not renewing DHCP lease in Auto mode. Connection lost after 24 hours.
WAN Internet interface is physically connected to cable modem - Motorola SBV6120E. Setup as DHCP server. Cisco RVS4000 is obtaining DHCP public IP without any issue, the problem is that the connection drop every 24 hours and I need to release/renew DHCP each day to be able to communicate after 24 hours. After I loose connection I need to release DHCP, the WAN interface goes down and I need to renew DHCP then. I receive the same IP address and connection is againg UP and working.
tried to load new firmware and also setup the router with default configuration, but without any change. as there is no auto-reboot function, it is really annoying to log into managment interface each day. I also loose remote access after 24 hours, so I am not able to access the rotuer from outside. My local provider do not support static public IP on WAN, therefore I have to use DHCP.
I'm setting up a Cisco Aironet 1141 (standalone mode, AP) to handle wireless traffic in the office. It gives out 2 mbssids, one of which authenticates domain users through a RADIUS server and places them in an appropriate VLAN (RADIUS options 64, 65, and 81). The other is a guest ssid that uses WPA-PSK and places users in the restricted guest VLAN. Physically, the AP is connected to a 3750 PoE Catalyst, to which RADIUS and DHCP servers are also connected. AP, SSIDs, RADIUS and EAP authentication all work. The configuration given below is a working configuration. People do get authenticated and do get placed in the appropriate vlan. The problem is that, once authenticated, the "Obtaining IP Address" phase on the client hangs and most clients timeout without getting an IP address. Given that the DHCP server is on the same switch and a test simple ASUS Wi-Fi IP gives out the same scenario (except the multiple VLAN) at the speed of light, I don't think that it's a problem with the network connections between clients and the DHCP server. After reading some topics here, I realized that probably other communication will be extremely slow, as well, but haven't tested that for sure. Clients are all non-Cisco - smartphones, notebooks, etc. Most of them are 802.11G, not N.
View 4 Replies View Relateda couple days ago my BEFSR41 started making trouble, and so far I have not been able to get it working properly again. When I hook up my laptop directly to the cable modem everything works fine, and I get an IP address via DHCP. When I connect through the router, though, the router status shows 0.0.0.0 for all DNS, gateway, etc. addresses, and even pressing DHCP Release/Renew doesn't change that.Also, in the log I see these messages:
2012-08-08 20:30:41 warning DHCP RENEW WARNING - Field invalid in response
2012-08-08 08:30:52 notice TLV-11 - unrecognized OID
Since I can connect to the cable modem directly, it seems the cable modem is not at fault.My overall setup is:
- BEFCMU10 cable modem
- BEFSR41 (not sure which version, but I believe it's a 4.x)
- WAP54G
Could it be that my provider (Cox Communications) has changed some configuration in their DHCP server, and my laptop (MacBook Pro) can handle it, but the router cannot?

I just bought an e4200. I was using a LinkSys WRT54GS running DD-WRT alternative firmware.
One feature that I really liked in DD-WRT was the ability to assign static IP leases from the DHCP server. I liked having all of my devices running with a predictable, known IP address on my network. I have a Home Theater PC, and various controller applications that run on iPhones, etc. - some pretty homebrewed. Configuring the firewalls, etc. was much easier with IP address based controls.
Is there a way to achieve the same within the e4200's stock firmware?
we finally got my Cisco refurbished E2500 configured and working downstream from a UVerse 3801HGV box. We had to change the default IP address of the 3801 because it conflicted with the E2500's default. The E2500 is set up to get its Internet IP address using DHCP from the 3801. This is working fine for normal web browsing, etc. However, anything that requires extended connections (downloads, streaming, etc) freezes after a couple of minutes, forcing me to refresh the action to get it started again. Extremely annoying to say the least.
I'm pretty sure that I've tracked it down to the E2500's configuration of the 3801's DHCP allocation. For some reason, the E2500 wants to set the DHCP Lease Time for the 3801's assigned IP address to 10 minutes regardless of the upstream settings from the 3801. The 3801's default is 24 Hours which I've changed to 168Hours (7 days), but the E2500 stays stuck at 10 Minutes. Specifically, I'm referring to the setting displayed on the E2500 under Status>Router>Internet Connection IPV4>DHCP Lease Time.
On the BEFSR41 v1 series and WRT54G series, what is the maximum value for the DHCP "Client Lease Time (in minutes)?" It seems that 2^16 -1 (65535) minutes is the max. This is about 45 days. has the max value changed with newer versions of these devices?

Have a client wanting to hand out public ip addresses to all clients from a PFSense Firewall terminating the internet connection.
How do I allow the Cisco Switches currently in place, configured with private ip addresses in the 10.10.x.x ranges and Vlans, where the main 3550 layer 3 has defined dhcp scopes for each vlan, to relay dhcp requests from all vlans to the PFSense firewall?
I assume I would take off the currently defined dhcp scopes for the vlans and configure each vlan/switch with the ip helper address and specify the PFSense firewall and that Nat would have to be disabled onthe firewall?
