    Can We Fix It? - Server Room Upgrade Part 2

    If Linus wants to use Cisco equipment, I have already put together a topology they could use. LinusTechTips.pdf

    Domain Connection Issue

    what did you set the IP address on the domain controller?

    I only have one DSL outlet

    What happened to your RJ11 wall outlet?

    Small Business Netwroking System Help

    You can also set up a VPN server using a Cisco router like a 2911. They go for about $100 on eBay. All you have to do is type this config into the router. I know it is quite a handful of config, that is why I am doing the hard work for you so that all you have to do is modify the variables and copy and paste it into the router. To configure Cisco AnyConnect for the router, you can follow this guide as well. I also recommend Namecheap to get a domain name and an SSL certificate for the SSLVPN. http://www.firewall.cx/cisco-technical-knowledgebase/cisco-routers/904-cisco-router-anyconnect-webvpn.html enable configure terminal interface GigabitEthernet0/0 description LAN interface here. ip address 192.168.1.1 255.255.255.0 ip nat inside no shutdown interface GigabitEthernet0/1 description WAN here ip nat outside no shutdown if the company has a static address then it will be: ip address x.x.x.x x.x.x.x if the company only has a dynamic address then it will be ip address dhcp ip access-list standard NAT permit 192.168.1.0 0.0.0.255 if the company has a block of static IP addresses and is routed to the WAN facing interface then it will be ip nat pool NAT-POOL <start address here> <end address here> netmask <netmask here> ip nat inside source list NAT pool NAT-POOL if the company doesn't have a block of static IP addresses then it will just be ip nat inside source list NAT interface g0/1 overload username admin secret <your own password here for management> line con 0 login local line aux 0 login local line vty 0 4 login local hostname <hostname here> ip domain-name <domain name here> (if the company has a domain name) crypto key gen rsa modulus 1024 ip ssh version 2

    Change public ip address

    How is the page for the IETF just facts and not education materials? I beg to differ. I will post some links to the IETF for DHCP as well to take a look at. https://tools.ietf.org/html/rfc1541 https://tools.ietf.org/html/rfc2131 OP: All you need to do to release the IP address is just reboot the Xfinity Gateway.

    BGP + OSPF Failover

    I am doing OSPF and there are limitations with the equipment that I have. I have my routers connected to my Cisco ASAs, so that is where I resolved to use OSPF. I only have DHCP for my ISP connections as well, so I can't use VRRP or any other first hop redundancy protocols.

    BGP + OSPF Failover

    I figured it out last night, turns out the routers I am connecting to in LV.Net and at my friend's house that runs https://voiptek.info was misconfigured on BGP and then I did redistribute while modifying the metric for 100 being the primary and 105 being the backup. When I failover, I change the OSPF metric for the default-information originate to 110 and change the metric for redistributing the routes from BGP into OSPF to 110 so that the backup with the lower metric wins the routing decision.

    BGP + OSPF Failover

    Basically, what I do for failovers is: log into the Primary router. conf t router bgp 64512 neighbor EBGP route-map Failover in neighbor EBGP route-map Failover out router ospf 1 default-information originate metric 110 what is supposed to happen is the routes are supposed to go through my CenturyLink circuit with the OSPF metric of 105 and then it is supposed to change the metric for BGP to 10000 and then prepend 64512 about 7 times and the Failover route map gets prepended 9 times making the prepend of 7 times more desirable with the metric 10000.

    BGP + OSPF Failover

    My failover testing plan is to failover BGP using the Failover route-map and then going into OSPF and increase the metric for the default route on the primary edge router. When I execute the failover plan, I can't ping the tunnel addresses but I can ping the networks behind them.

    BGP + OSPF Failover

    Hello Everyone, I am having an issue with failing over to my backup internet connection. How I have my home network set up is 2 internet connections, going to 2 different routers. I have OSPF routing inside my home and then going to my friends I have BGP set up between me and them. Anyways, without further ado, here is my configuration. Please let me know if there is something wrong with them. I put the configuration into spoilers so that way it doesn't take up too much space. Router A: Router B:

    limit bandwidth per device with modem?

    You put the static address as the source address and then the destination IP it will be 0.0.0.0. I would recommend putting your device as DSCP EF so you have top priority in your network.

    limit bandwidth per device with modem?

    Oh, alright, I recommend setting static addresses on your devices and use source based addressing QoS on the modem.

    limit bandwidth per device with modem?

    Just out of curiousity, are there any faster plans with CenturyLink that you can upgrade to?

    Static IP Assignment

    I would get a standalone cable modem and if you want to go with enterprise equipment, I would recommend Cisco equipment. If not, then get a consumer router that can create static routes. How I have my network set up is Cable Modem -> Edge Router (Cisco 2951) -> Cisco ASA 5510 x2 -> Cisco Catalyst 3560-X -> Cisco Meraki MR33
