I'm trying to configure my Cisco Router 2811 which is also acting as the DHCP server for my branch office for DHCP option 60 and 43 so Aruba AP's at my branch can discover it's master Controller? What is the command I need to enter in the Cisco router?
View 1 RepliesHave 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?
In one of our regional office I want to terminate 2 Internet links on a single 2811 Router and use both the links as primary and backup to enable site to site VPN. This also gives redundancy option if primary link fails. The Router has total 3 FE ports.
Current setup is terminating one internet link only on the router and establish site to site VPN to our HQ

I need DHCP Option 66 to be enabled my small business RV042 router, so the IP phones could know where is the TFTP server.
View 1 Replies View RelatedIs it possible to configure DHCP option 150 on the RV220? I have a Cisco 7940 IP phone that is trying to connect back to my office. The VPN is up and I can ping the relevant server but I can't see any way to configure the DHCP option.
View 5 Replies View RelatedI have a RV042 VPN Router with the latest firmware v4.2.1.02.This Router is connected to the main site by a VPN Tunnel.
Now, I like to configure some DHCP Option so I can put a IP Phone behind the RV042. The IP Phone should receive a IP by DHCP from the RV042 and of course, the IP of the Call Manager with the Option 150.
I can configure DHCP and it works fine but I can't find where I have or can configure Option 150.
I have sample lab dhcp-client ------- (vlan62) sg-300 switch (vlan62) ------ dhcp server
When I set on switch :
dhcp relay : enable
option 82 : enable
dhcp server address: ip of dhcp
When debug packets from client to server, there is no 82 option in dhcp discover packets. I mirror all traffic to mirror port with wireshark. I can see dhcp packets but without option 82.
Firmware version: 1.0.0.27
I have a very simple setup containing 3 C2960S switches:switch 1: central switch, acting as router between VLAN 1 en VLAN 2switch 2+3: edge switches, connected via 1 link to central switch, both on VLAN 2,Clients connect to switch 2 and 3 using dhcp, switch 1 uses dhcp relay to forward requests from VLAN 2 to the dhcp server on VLAN 1. So far so good.Now I want switch 1 to add option 82 to the dhcp requests so the dhcp server can see whether the request came through switch 2 or switch 3. I tried turning on dhcp option 82 support on switch 1 by doing.
View 2 Replies View RelatedIn RFC 951, the format of BOOTP packet was legislated, but the vendor information was not legislated in this document, so the authors of this document had described that :"If the 'vend' field is used, it is recommended that a 4 byte 'magic number' be the first item within 'vend'. This lets a server determine what kind of information it is seeing in this field. "
I think it meant that the format of vendor information wasn't fixed in RFC 951, and any vendor can legislate a new format of vendor information by itself. And the value in "magic cookie" can be set by any vendor.But in RFC 2131, the format of DHCP packet was legislated, and the "magic cooke" was fixed to values 99, 130, 83 and 99, I think it meant that the format of option information in DHCP packet was fixed absolutely and any vendor can't legislate a new format by itself.
Since the format of option information in DHCP packet was fixed absolutely, why the network device needs "magic cookie" to identify the mode in which the succeeding data is to be interpreted ? I think the magic cookie is not useful in DHCP packet because the format of option information is fixed. In other words, there is only one format of option information forever.
While configuring a 5500 wireless controller, i came across this option of DHCP proxy under Advanced tab of Controller Option.It asks for the dhcp option 82 remote id format & the dhcp timeout.
1. What is the significance of this & when do we use it?
2. Also, under each wlan ssid that we create, there is an option of dhcp address required under the advanced tab. Do we need to use this option, if we are defining a normal dhcp pool in our controller for that ssid.

I recently got a Motorola NVG510 (from AT&T, they changed our internet plan and sent a new router) and since then I've had problems with Skype. I think I've narrowed the problem down to there being no upnp on this router to enable, and Skype doesn't like that.So, is there any way I can make this option available, or some other way to 'simulate' upnp so Skype will play nice? I read somewhere else that "IP Passthrough" may be an option, but I'm unsure about that.
