A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

I have two questions on Viptela.
1.  client's edge router has two isp for internet without mpls. One is to verizon and other is ATT. do you think we can do SD-Wan?
2. if the above question is yes, are there difference between the following two cases? one is using two isp internet(verizon and att) and second is using internet and mpls?
Thank you

Working with an ER Pro8 ubiquiti edge router.

Have 13 public IP addresses, have added 3 to our WAN eth0 port.

One of them, 100.36.x.77 is the public IP for a new mail server I'm provisioning.

Port 80 requests inbound to that address are being mis-interpreted as "WAN Local" traffic and I get the login for the edgerouter instead of the debian 9 apache response from the internal server.

This is my first edgerouter and I'm at a loss after playing with this for several hours with no change in response.

I have two separate servers behind the router, both on eth1:
192.168.2.8  is my domain controller
192.168.2.2 is the new mail server I'm trying to provision.
192.168.2.0/25 is the subnet on eth1 (a 48 port ubiquiti switch)

192.168.2.128/25 is the subnet on eth2 (a separate 24 port ubiquiti switch)

Port 80 traffic seems to stop at the eth0 WAN interface.

External traffic to 100.36.x.77 is the destination that's being intercepted by the EdgeOS software.  There are Destination NAT entries to translate inbound traffic on 100.36.x.77 to 192.168.2.2.  I just created separate rules for ports 80 and 443 per this post:

https://help.ubnt.com/hc/en-us/articles/204952134-EdgeMAX-NAT-Hairpin-Nat-Inside-to-Inside-Loopback-Reflection-

This seems to imply that inbound traffic at the WAN port needs a separate NAT rule at the eth1 port to "catch" the traffic captured by the WAN eth0 port.

I am modifying a configuration that started with the WAN+2LAN(2?) auto …

Working with an HP/Aruba 3810M switch in a stacked/mesh configuration.  We would like to set up Policy Based Routing so that we can send traffic from different VLANs out to different internet gateway routers.  The 3810M would be the "LAN Router" for all VLANs with multiple directly connected routers for forwarding traffic to the internet.  

For example:
VLAN 30 with 172.30.0.0/24 traffic would be default routed 0.0.0.0/0 to 172.30.0.10
VLAN 40 with 172.40.0.0/24 traffic would be default routed 0.0.0.0/0 to 172.40.0.10
The 3810M would have IP 172.30.0.1/24 on VLAN 30 Interface and 172.40.0.1/24 on VLAN 40 Interface
*both default routes would only be used when no other static or directly connected routes exist.

I have done this before with Linux based routers but I am not sure how to do this with HP/Aruba.  Can anyone tell me how to configure this?

Thank you,
Jay

Hi,
What to adjust on server, as port 993 is not responding, like

182.173.77.220 is responding on port 80 (http).

182.173.77.220 isn't responding on port 993 (imaps).
while I already opened TCP & UDP Inbound & Outbound Firewall rules on 993 port.

How to force internet traffic from 2 x specific 'Guest' VLans on an Aruba Wireless Controller to forward to the DMZ VLan?

I thought about setting up a static route 0.0.0.0 / 0.0.0.0  to point to the DMZ Gateway IP address.

But I do not want the other VLans (company / employee related) to have their internet traffic through the DMZ.  Is that possible?  Or must all Internet traffic be routed to the DMZ and then routed back?  I am sure there is a way to do this.  In the older wireless system the Wireless controller's default route was set to the DMZ gateway.  That is telling me that all unknown traffic is forwarded to the DMZ(internet).

On the older wireless controller there are static routes set for company specific network traffic to use the default Vlan Default Gateway (Internal IP address).  The only problem that I see for setting up 0.0.0.0 / 0.0.0.0 to the DMZ is that I will need to setup a static route on the DMZ to send traffic right back to the controller(s)?  Unless I can only forward 0.0.0.0 traffic from specific Vlans to the DMZ?  Is that possible?

How can I force Internet-only traffic for 2 specific IP based VLans to be routed to the DMZ VLan and to let eveythign else use the normal company routing?  

We are using Aruba 7030 controllers and we can assign an extra/available port to connect directly to the DMZ VLan if necessary.

I work with quite a few small businesses who have been using commodity routers as their internet interface.  
Features vary of course.
Because many of these configurations are set by the owners before I've seen the system, there are many different devices in use.
I'd like to be able to recommend something sensible.  Thus these questions:
1) What small /low cost firewall would you recommend in place of a commodity NAT router and why?  (I'm not so much interested in simply testimonials, rather, rationale).
2) What real added features are there that you believe to be important?
I don't believe that dual WAN is a necessity here.  Redundant ISPs are almost never used - just like redundant telephone systems were rarely used.

Can you change the IP addressing on Netgear Jetpack-the DHCP uses the same IP address scheme as internal network so VPN won't connect

Packet can't flow between vlan 12 and 34 on cisco switch/router

I have a device on VLAN 12 (10.12.14.100), and it needs to communicate with a server on VLAN 34 (10.34.14.20).  A trace route to VLAN 34 from 12 gets to one hop on the gateway then stops.  How can I check why the router isn't routing to VLAN 34?

Thanks,

I have a voicemail server that is not communicating with the outside world, meaning it is not sending voicemail to email.  

I believe it is an issue with the router, but I am not sure what the actual problem is.  I used to have everything running through a Cisco router with this static route:
ip route 10.10.0.0 255.255.255.0 192.168.100.254

I now just use pfSense and I have a static route set up that says:

Network                                              Gateway                                     Interface      
10.10.0.0/24                                       ShoreTel - 192.168.100.254      LAN




Is there something else I need to do?  

If I ping from a host at 10.10.0.10 I can ping to 10.10.0.254 and 192.168.100.254, but not any further (for instance, the pfSense box at 192.168.100.1 is not reachable).  If I ping from 10.10.0.254 I can get anywhere (my network gateway, inside the 192.168.100.0 network, the next hop on the network, the internet).

We use auto qos for voip at switch interface. After entering command "auto qos voip" we can see the generated commands. One of them is "service-policy output ......

Cisco Nexus 7K: Can you create a policy map that NATs the source address of specified traffic
AND sets the ip next hop?

Current:
route-map gohere-or-pbr deny 10
  match ip address bypass-pbr
route-map gohere-or-pbr permit 20
  match ip address send-to-pbr
set ip next-hop 10.10.3.244

Imagined:
route-map gohere-or-pbr deny 10
  match ip address bypass-pbr
route-map gohere-or-pbr permit 20
  match ip address send-to-pbr
set source-ip-address 74.55.166.77
set ip next-hop 10.10.3.244

Or would that not be possible?

What do I need to do access the printer located at 172.17.10.201/24 (connected through LAN12 on VLAN 10) from VLAN 11?

A Cisco RV345 (Firmware Version: 1.0.01.20) is configured with multiple VLANs
VLAN 1 - 172.17.1.254/24
VLAN 10 - 172.17.10.254/24 - Parents
VLAN 11 - 172.17.11.254/24 - Boys

I have provided screenshots of the current settings. With those current settings, I cannot print (or even ping for that matter) 172.17.10.201/24 from my device (172.17.10.61/24).
If I set LAN12 on VLAN10 to 'untagged', I can print just fine from VLAN 10, but not from VLAN 11.

How do I proceed?
Thanks, Michael.

I am trying to implement a VPN using my Netgear Nighthawk.  The client is OpenVPN and the configuration files are downloaded from the router, this includes the client certificate which seems to be the problem.  When I try to connect I get the following error in the log

Looking around on the internet I don't find a clear explanation on how to correct the problem.

We have a user with a HP Officejet 6830 that we are trying to setup with HP EConnected/EPrint (print over Internet).  Everything goes smoothly throughout the setup, however, upon adding the printer the dot is orange not green on the HP EConnected site.  However, in checking the printer locally he have a green check mark for EPrinting.

The user has a basic home network with a AT&T UVerse (not sure of the exact manufacturer).  Do you need to open up certain ports for EPrint to work on one of these routers?  (In the past wet set one up on a home network with a Negear router and it was plug and play--green dot next to printer not orange.

I have Aruba Wireless Controller and HP Procurve core switch that connected and working with 4 different SSID. Each SSID setup with each VLAN. I have an issue connecting these two when I added new SSID with new vlan. For example, new vlan 88 with 192.168.88.1 / 24 on hp switch, and 192.168.88.2 /24 with vlan 88 on Aruba controller. I can't ping each other.
Other VLAN can ping each other just fine and these two devices connected directly.  What could that be wrong?
