typical ADSL configuration. My ISP only sends out DNS information automatically (PPP) - no static entries. I need to capture this information and relay it to users via DHCP. Currently when I do "ipconfig/ all" all DNS entries are empty.

Main site have 8 departments and each department have 60 pc's,remaining sites each have 6 departments and in each department have 40 pc's and in the design of WAN connection you use frame relays and that is the 100% growng hosptals and clock speed is 64000 bits/sec and security must don't access the unautheraised users from out side....how can I do this?

I have an old WRT54GS v6 that's sitting around collecting dust. I wondered if it's possible to plug it into the wired hub ( I have in my basement where the wireless is somewhat weak) to get the signal a bit stronger down here?I guess the operative terminology is 'wireless access point' I've found some instructions but they all say to connect the access point directly to the gateway via cat-5.. hoping I can do so with a hub. If not.. could I just switch the hub and the access point in the setup?

View 8 Replies View RelatedHave 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?
I'm having a problem getting DHCP working with an ASR9k as shown in this document. I've successfully implemented very similar setups with some Cisco IOS routers, but the IOS XR on the ASR seems to be defeating me. Router A (happens to be a 3750)A DHCP/BOOTP/TFTP server, connected to router ARouter B - this is the ASR, running software version 4.0.3.Router A and B are connected by a layer-3 link.Router C (happens to be a Broadcom embedded router). It's connected to Router B by a VLAN trunk link.Device 1, this one needs to get its configuration by DHCP/BOOTP/TFTP. It's connected to Router C by a VLAN trunk link.Device 2, this one doesn't need any DHCP/BOOTP/TFTP. It's connected to Router C by a VLAN trunk link (its port is the same as Device 1's) Device 2 works great - it can ping the DHCP/BOOTP/TFTP server (and vice versa) and everything else it needs.

View 4 Replies View RelatedI have a firewall that I want acting as a DHCP relay. This firewall has a number of VLAN interfaces serving clients. The DHCP relay destination is the IP address of a Windows 2012 Server running Microsoft DHCP which has multiple scopes configured, one for each client VLAN.What I'm finding confusing is how the DHCP will identify the client. Does the DHCP relay insert an identifier of some sort (opt. 54?) based on which VLAN the DHCPREQUEST comes from and then this identifier can be configured to be recognized on the DHCP server?

View 15 Replies View RelatedI've a home lab which consists of three 2610xm routers and I have configured two routers back to back with FR subinterfaces. The commands are used are;
R1
frame relay switching
int s0/0
encap FR

frame-relay intf-type dce
[code].....
Everything works great with this config and I know how to configure without lmi too. My question is more for the CCNA exam and fill the gaps in so to speak. The question is when you configure FR with static mappings and inverse arp do you need actual frame relay switches on the other side of the link or can I configure on my home labs routers. I know I am gonna try and configure this as well, but can I configure multipoint on my third router with a different physical interface. Like R1 with s0/0 to R2 s0/0 and R1 s0/1 to R3 s0/0 with subinterfaces.
I have a data center with virtual desktops and other shared infrastructure serving remote sites, some of which are connected to the data center with GRE over IPsec.
IP address management including DHCP is centralized in my architecture, but I simply cannot figure out how to relay DHCP requests through GRE over IPsec to my DHCP server cluster. I am working with Cisco 800 series VPN peers, and the VPNs are terminated either on a 1841 or a Juniper SRX. Everything else is just fine and dandy, but DHCP is not forwarded across the GRE tunnel.
As a workaround I am forced to use local DHCP pools on the VPN peers, which is extra work from a management point of view, and also precludes static IP address assignment where a local DHCP pool is in a VRF. My LAN devices are mostly thin clients, so I don't care if DHCP stops working when the WAN link fails. As such local pools have no upsides, they are only a tremendous hassle.
My config is very basic, public WAN in global routing table and WAN + GRE tunnel in a VRF. NAT is not used. Here are the DHCP-related configs I have tried:ip helper-address on the LAN gateway, both with and without ip forward-protocol udp bootpcip dhcp pool with relay options configured
In every case, I can see the UDP broadcasts hit the LAN gateway, but relayed packets never arrive at the other GRE tunnel endpoint let alone the DHCP server.
I have defined several V LAN's and the corresponding IP Addresses on the SGE2000. The static routing works fine. On one V LAN there is a Windows 2003 DHCP Server which I have defined as DHCP Relay Server (Option 82), but no packets are relayed. Has anyone a functional setup, with dhcp relay?

View 1 Replies View RelatedI am trying to get an understanding of some behaviour I am seeing on my N7Ks regarding DHCP relay.I have two identically configured Vlans interfaces both configured with the same two dhcp relay servers in the same order. The only difference between the two vlans is that one is HSRP active on the A side switch and the other is active on B side switch. All clients in Vlan136 (active on B side) are getting DHCP leases from the first of the two dhcp relay servers configured while all clients on Vlan 137 (active on A side) are getting DHCP leases from the second of the two dhcp relay servers. I would expect that all clients on both vlans would get leases from the first relay server configured unless that device was unavailable.

Here's what I'm trying to figure out:
My network is set up such that I have a Wireless Network in VLAN 1, which is the primary network that we use. The subnet is 10.5.1.x.
My goal is to set up a completely isolated Guest Wireless Network, however it would work best. What I am trying to do now is I created a seperate VLAN (VLAN 2, IP range 10.5.2.x) and turned on DHCP on the WRVS4400N. However, in the Guest Network, it is always picking up a 10.5.1.x IP which is handed out by the DHCP server (10.5.1.5, Win 2003) and still routing all of the traffic to/from our private network.
Here's What I have set:
Wireless>Security Settings>Guest Network (SSID 2)
Wireless Isolation (between SSID w/o VLAN): EnabledWireless Isolation (within SSID): EnabledSetup>LAN>VLAN 1
Router IP 10.5.1.1, WLAN IP 10.5.1.3DHCP Relay for 10.5.1.5Setup>LAN>VLAN 2
Router IP 10.5.2.1DHCP Enabled for 10.5.2.x subnetDHCP Relay option is grayed out (not sure why)Setup>Advanced Routing
Inter-VLAN Routing: Disabled
Any way to solve this would be fine. I just do not want traffic routing through our internal network. Ideally, if I could get the Windows server to hand out 10.5.2.x addresses, that would be perfect, but I'm not sure how to configure it for such.
