How to assign NAT IP to server from Firewall
View 2 Replies View RelatedWe are trying to configure vrf aware GET VPN with COOP having primary and secondary key servers and also 3 GM routers. All GM routers we use are Cisco 888 and Key servers we use cisco 2911 routers. All GMs crypto maps have been applied into Vlan interface as there's no L3 interface on 888 routers.
Always members can form a tunnel with primary KS, we have configured redundancy with secondary key server and listed on each GM primary and secondary KS on GDOI group.
The issue we facing is that whenever we shutdown the primary or secondary servers the tunnel is not forming with available KS unless otherwise we mannually clear the crypto session. In another way when primary KS down it doest not fall back to secondary KS and no GM get registered. We have already played with all the timers such as DPD, SA lifetimes, GDOI rekey lifetime etc and also exchanging the keys (import/export) with KS and COOPs but there's no luck. We could see the following message was seen on both KS.
[code] 192.168.1.3 is the primary KS and 192.168.1.6 is the secondary KS.I captured attached debug output from 1 GM and secondary KS while I shutdonw the primary KS and also attached is our senario we were trying get work.
Also attached is the show output from both KSs when it form a tunnel with GM.

I have read how to configure the Virtual Servers - Forwarding url...and added two entries, one for port 44612 and one for 32680 , my pc ip is 192.168.0. 100.Before I installed the router (my pc was connected directly to the lan connection) all was working just fine.And I double checked that the ports are not being blocked by firewall.
I have a server windows 2008 that I would like to have a nic teaming configuration, the server has two nics, each nic is connected to a different switch. One is connected to cisco 2960 and the other is connected to cisco 2950. I have read here in forums about nic teaming but using the same switch. I have not found using different switch. Is this possible?

The purpose is that users in vlan 1 should get an IP address from DHCP server1, and users in vlan 2 should get an IP address from DHCP server2. Both DHCP servers are configured in a stack of C3750 switches, which acts a a L2 switch.

View 1 Replies View RelatedI am working with a strange problem at the minute with HP's NIC Teaming with Transmision Load Balancing.We have a HP blade system the Server is connected to 2 cisco 3020's and then those 2 switches are connected to a 3750 Stack consisting of 2 Members.
Theres an LACP ether channel consisting of 4 Gigabit Ethernet Ports to each 3020 from the 3750 Stack.They both have exactly the same configuration and all ports are up and the channel looks healthy.
When setting the Preference order on the server if I set the NIC connected to the 1st Cisco 3020 as primary i.e. Tx/Rx then everything is fine.If I set the NIC Connected to the 2nd Cisco 3020 as primary then all seems fine i.e. I can ping it, it can access services outside its own vlan and the internet. It cannot however ping anything connected to the same subnet and VLAN on the 3750 Stack.
Doing a packet capture on a server connected to the VLAN on the 3750 stack I can see the Echo Requests coming in and the server sending an echo Reply but the echo reply never gets back to the server with the teamed NICs.
I did a Layer 2 traceroute and all looked fine, all the MAC Tables were good.I thought maybe it was a layer 2 loop causing the problems but I have checked and re-checked STP and can't find any problems. STP has picked up one intentional loop and blocked it.
I've raised a ticket with HP to see if they can point me in the right direction but I don't think it is a problem with there Drivers. It definately seems like a networking problem.
We have a Power Edge T310, sporting two Broadcom 5716C LOM's. We also have a Power Connect 5524 switch. Good opportunity to team the two network connections using 'Link Aggregation (802.3ad)'. Downloaded the most recent management software off the Broad com site. Installed BACS 3 on the Power Edge, running Windows SBS 2011, which has Windows Server 2008 r2 x64 as it's base.
Started BACS and tried to configure teaming. But there's no teaming-section in BACS. I removed, restarted the server and re-installed the Broad com software, but still no teaming section? How do I solve this?
I have a wap4410n. It was performing poorly. Only letting some computers on the wireless while not letting other. I was able to login into the device and I went through each of the settings pages to see if there was anything set wrong. I soon found there was a firmware upgrade available.
So over a wired connection I started the firmware upgrade after waiting 10+ minutes I was unable to reach the device and the web page said it was waiting for the ip address of the device. So I rebooted the device.
I can not ping the device. I can not see it on any subnet. I have tried the reset button multiple times.
The ethernet and power lights are on.
Having a design where an IBM bladecenter has two Nexus 4001i switches and each switch is connected to a Nexus 5k vPC pair, is it possible to configure active-active nic teaming on the hosts (blades) considering that the Nexus 4k switches are unaware of each other and blade has one connection to each 4k over either emulex or qlogic 10G CNA?
View 1 Replies View RelatedI'm trying to configure a SG300 to be reachable beyond its own subnet. Its IP address is configured by DHCP to 192.168.2.2/255.255.255.0. It is possible to ping the switch from the same subnet but not from outside. The switch is set to layer 2 mode. All routing should be done by the gateway.
Here's what I have checked so far: The default gateway and netmask are set correctlyThe gateway can ping the switchHosts in the 192.168.2.0/24 subnet have connectivity to other networks through the gateway (i.e. gateway configured correctly)Administrative interface > IPv4 interface shows the correct ip address, netmask, and gateway (greyed out because it is assigned by DHCP)the switch can ping other hosts within the same network
Is there some kind of firewall setting that prohibits the switch to respond to ip packets from outside the subnet?
I need to connect 10 branches to a datacenter using cisco 861 routers because the ethernet sollution the provider gave us can't assign more than 32 MAC addresses for whe whole network. So we have all our servers at the datacenter with a central firewall/router and all remote branches with a static route to this router. We would like to make all branches local networks available through NAT or another better solution so network devices at the datacenter network can communicate with all local devices accross all the brances.
I've tried to set up a dynamic NAT from outside to inside the network and didn't work, set up static ip routes for both datancenter and remote branchs and also didn't work. I just would like to make the routers work in a transparent way, no blocking of anything, passing all traffic in and out the network.
On my server I host several websites.Last Monday we got our FttH-connection and I'd set up my D-Link DIR 655 to manage our server and other computers.In the webconfig of my router I set up the Virtual Server for several applications (Telnet - 23, HTTP - 80, HTTPS - 443, FTP - 21, SMTP - 25, POP3 - 110, IMAP - 143 and also ports 20, 22 en 81) redirected to my server's IP address.For these items the private port and the public port of each item is the same port number; the protocol is TCP for these items. I didn't change the options Schedule ("Always") and Inbound Filter ("Allow All").
The DNS of my domains (samendienen.nl and some other domains) is set to my new IP-address.May be I forgot some other settings in my D-Link-router.what I have to do to make my websites reachable?
Need clarification on the VPC with 5k and 2248 Fabric Extenders. My question is can each fabric extender uplink to two different 5ks, and at the same time, have servers connected to two both fabric extenders with a VPC.So basically, the server NIC will team with two different fabric extenders, and each fabric extender will connect to two different 5k's.
View 3 Replies View RelatedThe aDSL circuit is up and connected and I can reach the internet, however not all sites on the internet are reachable. This is occurring on two seperate 887VA’s and the circuit has been tested with a netgear router and no issues occur. The router has been tried on 5 different ADSL connections and the same problem occurs although more websites can be reached on a home broadband connection (ADSL2+ Annex A) as opposed to the problem being more severe on an ADSL2+ Annex M circuit. The problem seems to affect websites that are full of adverts more than sites that have single domain landing pages.
The sites that I cannot reach are pingable. This happens on multiple machines behind the router. The same config is used on an cisco 877-M router with no issues.

I have one ASA with two tunnels. Each going to a different 3rd party Checkpoint firewall (site A, site B) Each site has two servers (A1, A2, B1, B2)I can only connect to A1 and B1. any connection to A2 and B2 fails. I have defined B2 and A2 in the crypto map to be protected.If I only have B2 or A2 in the crypto map ACL then the tunnel fails. Phase 1 does not come up. Its as if the ASA is ignoring the entries for B2 and A2.ASA running 8.4(2).I have also trashed the VPN and built via the wizard, same result.

When I run the ISE diag tool connectivity tests I am able successfully ping the devices from each other using both hostname and ip and the nslookup also works fine between both nodes. Ping and nslookups also work from different networks within the environment. The two nodes are in the same vlan on a 6500 vss pair but on different switches of the pair.
