A Windows Server 2008 r2 with 2 internet ports. One (IP: 10.0.96.132) connected to company intranet and one (192.168.10.1) as DHCP server connect to several PCs (192.168.10.**) through a switch.The problem is the PCs (192.168.10.**) can ping the DHCP server (192.168.10.1) , while DHCP server (192.168.10.1) can not ping (192.168.10.**).How to configure the server so that all these PCs can access the intranet?
I insert data from two clients.(1 window server 2003,2 XP clients ) the two client print paper and the printer is shared printer. At the same time two clients print paper and the printer stop working. So I restart my two clients and server. After restart the clients cannot ping to server.
I connects to the wireless box and has full signal but an exclamation mark is present.I have run some tests and the IPv4 and IPv6 say they have no internet access.I also run a full test and everything passed except the ping test which failed and it said: no response:default gateway response: dhcp server it suggested disabling security firewall but i'm not sure if that's the correct thing to do or even how to do that!
I have 2 units Cisco WLC 5508 running software version 7.0.220 with 70 over units Cisco AP 1262N and 1242AG. Some of wireless clients having problem to get the correct IP address from the DHCP server. There are 2 units of Microsoft DHCP. Both DHCP server ip have been configured on the Interface at the WLC. The core switch also being configured with ip helper. I've attached the debug output of one of the wireless client during the problem.
How to configure cisco 3560 to force the client only can get ip by dhcp-relay server ?
The company i am working in has 5 vlans which have been set an lay-3 switch(3560), uses the dhcp-relay server .(in svi configuration: ip helper-address X.X.X.X) well , that works ok~
Now , I got my problem: I need to force the client only can get ip by dhcp-relay server, that means if anyone set static IP manunally , he can't really access to anywhere (to provent anyone set static IP with malignancy )
I know if a h3c router , how to set this configuration n svi configuration : dhcp relay security address-check enable ) the how to configure on a cisco 3560 ?
I am trying to configure interface vlan1 to get an ip address from dhcp by entering the commnad ip address dhcp ios rejects the dhcp portion of my command as not recognised although it is referred to in Cisco manuals.my IOS version is c2950-i6k2l2q4-mz.121-22.EA14.bin.I get the same problem when I try to configure ip http secure-server on the switch. Is this a known bug or whether I have the correct IOS version for these commands?
Haveing issue with DHCP server handing out IP addresses to client connected to VLAN5 interface.ISP Router>Firewall -(WatchGuard Drop-in mode) I have several 3750 switches and one acting as a L3 switch. The L3 is configured as follow: [code]
If I connect a laptop to int fa1/0/10 I DO NOT get an IP address from the 10.100.0.8 scope. If I connect to another interface within the VLAN 1, I get an address from the 10.100.0.0 range.
Do the problem caused by the modems itself or it just sign of faulty Ethernet switch (using 20 port Allied Telesis ethernet switch). Sometimes I cannot connect to internet due to "unidentified network" buy i can resolve this problem by restarting my modem + switch.
I installed window server 2003 in a old Pentium III server as a standalone test server. Now I want to use it as a print server and connected it to the domain. I can ping workstations and other servers from that test svr. But i cannot ping that test server from the work stations.
My parents Windows 7 PC has suddenly stopped being able to connect to the Internet. Using the "Diagnose problem" feature in the Manage Network Interfaces panel results in a message claiming that it cannot reach the DNS server and that the connection needs to be reset. Doing so has no effect. It is connected to a DSL router via an ethernet cable.The NIC is set to dynamically receive its IP and DNS settings via DHCP which it obtains from the DSL router. Executing ipconfig from a DOS prompt shows that this is occurring as expected, with an assigned IP of 192.168.2.10. The gateway and dns are set to the IP address of the router, which is 192.168.2.1. Note that I can't even ping the router at 192.168.2.1.I also tried static settings in the available range and tried using open DNS IP addresses.
They also have a laptop which connects to the same router wirelessly using DHCP and it is working fine. Using this laptop, I can log into the router and see both it and the problem PC in the list of connected devices, each with the dynamically assigned IP addresses as seen using ipconfig on each. Unplugging the ethernet cable shows the connection status changing in the list of connected devices in the router. From the laptop, I can ping the router and running ipconfig shows that it obtains the same gateway and dns as the PC and the next available IP - 12220.127.116.11.So this leads me to believe the following:
1- The router, NIC and cat 5 ethernet cable are working fine at the hardware level.
2- The DNS settings in the router are fine, as the laptop works
Perhaps coincidentally, the same day it stopped working they received one of those bogus "This is Microsoft calling" calls claiming their PC was infected, but they had heard of the scam and hung up. Naturally, I started suspecting a virus, but a full system scan using McAffee produced nothing. If it was a DNS changing virus, would I not still be able to ping the router using the IP address?
I have a VPN client running on a laptop connected a DSL circuit. The VPN client is configured correctly for an external address on another firewall, this external firewall passes through ISAKMP / IPSEC to an ASA where it terminates. The client authenticates and gets an address from the client pool (VPNCLIENTS – 10.2.16.x / 24) and the tunnel completes with no problems. From the internal ASA I can ping any internal network behind the 10.0.3.240 interface (INSIDE) and I have a route on the inside network to get to the 10.2.16/0 clients to point to this address (10.0.3.240). All good so far.
Now the problems begin. I cant ping anything from the VPN clients (10.2.16.0) network to anywhere, I cant ping any interface on the ASA or any internal network. I also cant ping the client from the ASA and therefore not from the internal network either. This configuration is bare bones configuration so I don’t even have the NAT exception rules added. Network diagram attached too.
I have more than 10 PC om my Workgroup, using DHCP on network, but I have one PC alwaws got wrong IP (auto from dhcp), and can't connect even using static IP (status connect, but can't ping to gateway and other IP)Here "ipconfig /all" on one of PC that work. [code]
I am having a weird issue with my Cisco 7200 router. From the router i am able to ping and reach out to the internet but from the client i am able to reach out to the internet but unable to ping I am not sure where is the issue but when i traceroute to it my packets are dropped at my routers interface. All my pings from the client time out. I checked the Access list to make sure ICMP is not blocked. Following is my running conf
ip audit notify log ip audit po max-events 100 ip ssh break-string ~ ipv6 unicast-routing no ftp-server write-enable
I just setup my home network with Pix 515 acting as my router/firewall but I can't seem to ping my internal PC from my ASA. I can access the internet and ping my Pix 515 inside interface from my pc but I can't ping my pc from my Pix 515. I can also renew/release IP's from my PC. I also did a packet tracer and it says that it was dropped due to an access list but I have one in place. Also my switch has the default config. Below is my config
Internet <----> Comcast modem <-----> Pix 515 <-------> Cisco switch <-----> PC MYFIREWALL# sh run : Saved
I recently upgraded from a WRT54G and am having issues with a Win7 PC with wireless-N. Initially I had it configured static at 192.168.100.100 and everything worked, but the speeds were miserable (I followed all the forum posts and recommended settings). I noticed in the Status section of the router pages that the system showed up with the correct MAC address, but the IP showed as 192.168.100.10, which is the same as the router. Assuming this might be causing issues, I set a reservation for the system at .100 and set the client to use DHCP. However, now it won't pull an IP address at all. The status pages show the client with the correct MAC address, but an IP of 0.0.0.0. I've verified the MAC address a dozen times and rebooted the router and the client dozens of times with no change. Even when I removed the reservation, the system won't pick up an IP. I have a wireless-G client that's pulling an IP fine, so I know it's sort of working. The wired LAN is working fine, too. There are no IP conflicts, either. I changed DHCP to 'Always Broadcast (compatibility for some DHCP clients), but no change there, either. The client sees the network and still has a good signal, but just won't grab an IP.
I have a fresh install of LMS 4.0 on Windows Server 2008 Standart SP2. I have one NIC with static IP configuration. I also disabled DHCP client.The problem is follows: when I go to Inventory - Device Administration - Add/Import/Manage Devices, I always get this error:Error in communicating with DCR Server. DCR Server may be down. Please start the DCR Server and then refresh the page.Reload server/ Daemon Manager dont solve this.I try to beat this problem 2 days already. Second uninstall also doesnt solve the problem..
About a week ago I tried to clear log files which was 270gb (syslog.log) and after that restarted the server. And all inventory devices suddenly disappear! I could find it from search menu but cant access - cisco works said that there is no such a device in Device Repository or I havent enough right to view it (but i logged as admin). And after this i failed to add any device in Inventory. So I reinstall Cisco Works and get that DCR error..
My old office uses Cisco 861 as a VPN router, with the WAN side setup to receive a dynamic IP assigned by Time Warner cable. Now we switched to a new office, with TowerStream which provide 4G SLA'ed 10Mbit service with static IP, and I get a Cat 5 ethernet down from it.
So all I did, was to go my "interface FastEthernet4", and typed ip address 18.104.22.168 255.255.255.252.Changed speed to "speed 100" and "full-duplex" (as instructed by the ISP).
I also did "ip default-gateway 22.214.171.124", which is the default gate way assigned by the ISP.I also typed "ip name-server 126.96.36.199" to setup the new DNS, am I doing anything wrong? I can't even use the router to ping google, but if I connect the laptop directly to the outside line, then it works, so I know the outside line is good.
Why can't I connect to the internet? I wasted several hours already trying everything in my book to trouble shoot a supposedly very simple configuration change. Do I need to change something related to NAT when changing to Static IP? My NAT was working just fine before when under DHCP.
The below is my full config (some IPs changed to preserve anonymity):
============================================= Building configuration... Current configuration : 16628 bytes ! version 12.4 no service pad service tcp-keepalives-in service tcp-keepalives-out
(Router is ISR 1921)This is doing my head in. I am not using NAT, there are no ACLs, there is no split horizon.Here is what I have. It is practically generated by CCP. When connected I cannot ping the loopback interface or the gig0/0 interface, (not to mention anything else).
version 15.0 service config service timestamps debug datetime msec service timestamps log datetime msec no service password-encryption ! hostname dcsgw1
I am trying to connect my 2800 Series CIsco Office router with VPN client software from home. I can successfully authenticate and get the IP address from the pool configured but couldnt ping any LAN Ips including default gateway. I am pasting my router's configuration.
IP Address Of LAN: 192.168.22.x/ 24 IP Addresses handed out to Clients: 10.10.10.5- 10.10.10.20 aaa new-model ! ! aaa authentication login default local
I have noticed that my virtual-access interface comes up but the line protocol of virtual-interface remains down as follows:
Virtual-Template100 x.x.x.x YES TFTP up down
Also The client PC picks up a random gateway of 10.10.10.1 which I never configured anywhere on the server.
I'm configuring ASA 5510 Remote Access VPN, I can connect from Cisco VPN Client to the ASA VPN. I obtain from ASA some routes to inside networks, but I can't do any ping to those inside hosts. I have got those error in ASDM log file: [code]
I have configured Remote Access VPN on an ASA5500 Firewall. I am able to login normally and Ping Internal servers on the LAN. However, The servers cannot ping my IP address that i am taking from the RAVPN Pool. So it is a one way communication.
I have a setup involving 3 clustered AP541 running off a sg300 switch. The wireless network setup VAP has one entry for vlan 1 with station isolation disabled. Is there anything more I need to do to allow one wireless client to ping another wireless client - am I missing something - i assume this is possible.Needless to say wireless clients can ping non wireless clients and vice versa quite happily. Everything is running with factory default settings more or less.
