I'm trying to setup an 877 to sit in front of a firewall. As the firewall has a public IP I do not want to use NAT. The problem I'm having is I can't seem to route through the 877. From the 877 i can ping 8.8.8.8 From the internal network I can ping the dialer0 interface of the 877 but cannot ping 8.8.8.8
View 2 RepliesI've enabled antispoof on all interfaces on asa 5510.If you start a traceroute to a network on the default route, everything works, since replies comes to an interface with route 0.0.0.0/0 defined.If you start a tracer route to a network that is NOT on the default route (let's assume coporate MPLS), you only get response from first carrier router, the other are discarded because of anti spoof violation.
I have ICMP inspection and icmp-error inspection enabled.
I have a NAT/Port Forwarding going on for which I need to deny all traffic except the one mentioned in my ACL/route-map, So, port forwarding from host A to host B, all else, deny. The port forwarding works, but for some reason.

I have two routers and an ASA, all of which are in area 0, it's a pretty simple config. The two routers are connected to some other devices (also in area 0) that pass of an external route to a particular subnet, let's call it 192.168.4.0. The routers are getting it just fine, but the ASA is not:
I have a Cisco 819 router and it's the first time I've configured any Cisco product. Starting from scratch, I have managed to get 3G working and the VPN to connect but so far no packets can route down the VPN tunnel (the other side is openswan/shorewall on CentOS5).I've been pawing over lots of guides and forum discussions but seem to be a bit lost. I suspect I'm missing some access-list definitions but don't really know how to go about it. I want the network behind the Cisco 819 (10.x.x.0/20) to be able to access the internet through the interface Cellular 0 but also the VPN remote network (192.y.y.0/24)When I ping from the other (non-cisco) end I see on the Cisco 819.

I will add that after I get the routing working.

View 6 Replies View Relateda) one router with two ethernet interfaces (LANs) and a serial interface. The serial interface is connected to the internet, dynamic nat is used for hosts in the two lans. A web server has a private address of 172.168.50.10 and it is being translated to the internet with serial's interface 68.32.x.x (public ip) with static nat. Clients in the internet type the public address to access the web server.
b)Problem: clients inside the LANs cannot access the web server by typing the public address, they use the server's private address instead, this create a problem with DNS static entries in the HOSTS file in the OS. It is a test server and is only available to authenticated users (lock and key ACLs), so no need to make a real DNS record. The entry in the HOSTS file points to the public address.
c)Question: how can a create a route map to change the public address in the HOST file to the private address of the test web server everytime a user in the LANs type the domain name.
I am advertising the 172.16.10.0 network from R5 to R1 via EBGP. The problem is that on the Router R1 I see the route 172.16.10.0 whith show ip bgp command but in the show ip route don't appear.I thinked that the problem was SYNCHRONIZATION,so that will activated synchronization on the routers R1 and R4 but don't work. Furthermore the routers R2 and R3 neither receive the route via OSPF.
View 11 Replies View RelatedI know RD is used to make an IPv4 address unique in an MPLS VPN system.I don't understand why a PE sends the RD when advertises a route via BGP.I thought RD were only local significant. But I made a packet capture and the RD is actually sended inside the MP_REACH_NRLI attribute:
(from packet capture)
Label Stack=19 (bottom) RD=12:1, IPv4=172.16.22.0/24
MP Reach NLRI Route Distinguisher: 12:1
Why the RD is sent? I suppose that the PE receiving the update checks the Route Target Extended Community to know to which VRF associate the update and not the RD.I made a test between PE1 with RD 12:1 and PE2 with RD 13:1 and there was full routes exchanges, the same when both PEs were using the same RD(all this configured in the correct VRFs). The only difference is that PE2 now shows in their corresponding VRF BPG table "Route Distinguisher 13:1".

I have a 2801 with dual ISP connections, and I have configured route-maps to direct voice traffic over ISP1 (working just fine), and I'm attempting send all other traffic over ISP2 (traffic is load-balancing instead). The connection to ISP2 is DHCP, and I have configured a route-map to route this traffic using the 'ip next-hop dynamic dhcp' command, but when I look at the route-map, it states the following: ip next-hop dynamic dhcp - current value is UNKNOWN..Is there something that I need to enable in order to see the next-hop, and properly send traffic over the ISP2 connection?

We recently purchased a SF 300-48P to replace a Layer 3 3Com switch that died.

I posted also under Service Providers for my problem with MPLS/VPN. I just noticed I have the same issue with plain IPV4 BGP. [URL] I have two 7600 running on SRC3 and SRD6. Both acting as RRs.
I noticed that RR1 is reflecting the route to this other 7600 iBGP peer but not installing/importing the route. Other iBGP speakers are able to install and import the route. Is there any issue with 7600 SRC/SRD IOS for Route-reflection?
iBGP policy is similar to all but only the 7600 is unable to install the route. Other 7200 ibgp peers are successful.
I have a 3845 that will not let me ping to the internet from my PC.On interface g0/0 I have a connection to a internet connection (another router), using DHCP to get it's address (it gives g0/0 IP 192.168.0.3).On interface g0/1, I have a connection to my LAN (I assign the interface IP 10.10.1.1).
I can ping the router. The router can ping the internet, do DNS resolution, etc.I have ensured routing is enabled. The only route I have configured is a default static route: 0.0.0.0 0.0.0.0 192.168.0.1.Oddly, if I choose 0.0.0.0 0.0.0.0 g0/0, I cannot ping sites on the internet from the router.
I tried setting up ip nat inside for my LAN and ip nat outside for the WAN/internet uplink, but this did not work.
This was the issue, I missed finishing the NAT setup.I can make the router ping out all day, and have my PCs ping the router, but getting the connection between the two is not working.
The traffic flow on the network is fine, but we are not able to access our remote locations.Using the example in that thread:Let's use your example. If your Vlan interfaces are configured on the 3560:
interface Vlan10
description LAN A
ip address 10.20.102.1 255.255.255.0
interface Vlan 104
description LAN B
ip address 10.20.104.1 255.255.255.0
Device A has his default gateway set to 10.20.102.1 (interface Vlan10) and device B has his default gateway configured to 10.20.104.1 (interface Vlan104). If device A (10.20.102.55) wants to talk to device B (10.20.104.25), the traffic would have been routed on the 3560 between Vlans 102 and 104.
As for DHCP, if there is a server on a separate network (let's give the DHCP server an ip: 192.168.2.15) you would configure an 'ip helper-address' on each vlan, which will forward each DHCP Discover broadcast to the DHCP server as a unicast packet. This is done because by default the router (3560) will not forward broadcasts.
interface Vlan10
description LAN A
ip address 10.20.102.1 255.255.255.0
ip helper-address 192.168.2.15
interface Vlan 104
description LAN B
ip address 10.20.104.1 255.255.255.0
ip helper-address 192.168.2.15
Now lets say LAN A and LAN B are located in SITE1. A second site, SITE2, has the address of 10.20.128.1. I can't ping the Site2 location from the LAN B (10.20.104.x) segment in Site1. I think I should set a static route on our switch with something like this:
ip route 10.20.0.0 255.255.0.0 10.20.102.10
The address 10.20.102.10 would be a wan router in this example.
We have a 3845 router at one of our remote sites. We want to connect the router to our central office using the two gigabit ports. One link would be the primary and the other would be the secondary (backup).
The router is running EIGRP and the two ports would have different ip addresses. How can we set up the router to use gi0/0 as the primary port and gi0/1 as the secondary (backup) port? The backup port would only be used if there was congestion on the primary port or if the primary port went down. Is there a way to force the router to make the primary link the best route?
Remote Router Sample Config:!
int gi0/0
desc primary link to Central Office
ip addr 10.0.1.84 255.255.255.0
