The setup: rb2011; routeros 7.3
2 ISPs (1 is turned on while another is turned off)
the router itself as a l2tp client
some static routes before l2tp
I want to be able to redirect all traffice from particular ip from lan to 1ISP before lwtp connection.
I have spent about 4 days of googling, tried it:
This is my answer:
Create Address list:
ip firewall>address-list> add comment="samme comment" address=192.168.0.50-192.168.0.51 list=list50-51
create mangle:
ip firewall mangle> add comment="same comment" chain=prerouting action=mark-routing new-routing-mark=INTERNET-50-51 src-address-list=list50-51
create route:
ip route> add comment="same comment" dst-address=0.0.0.0/0 routing-mark=INTERNET-50-51 gateway=IP of ISP1
create nat
ip firewall>nat> add comment="same comment" chain=srcnat action=masquerade src-address-list=list50-51 dst-address=0.0.0.0/0 out-interface=Interface of ISP1(PPPOE)
But when i put static route, i can't even ping my lan/gateway.
Want to solve this dumb situation.
I bought a second router and I set it up using LAN/WAN configs. From the secondary router clients, I can ping and access clients on primary router. But from the primary router, I cannot access any clients on secondary router. I cannot even ping the second router IP address.
Primary router IP: 192.168.100.1
Secondary router IP: 192.168.100.2 and 192.168.0.1
DHCP enabled on second router: 192.168.0.2-100
Ping from 192.168.100.1 to 192.168.100.2 passed only when I enabled "enable wan response" option.
But I cannot ping 192.168.0.1. I dont understand why clients from 192.168.0.0/24 network can access 192.168.100.0/24 network but the reverse cannot be achieved. Tried disabling firewall and security in router 2 but did not work.
Could you help me out?
If your pings are going through 192.168.0.1 (DHCP) you should add a route on the secondary router (assuming on Linux):
router2$ route add -net 192.168.100.0 netmask 255.255.255.0 gw 192.168.0.1
I have two IP schemes a) 10.0.1.0/24 and b) 10.0.2.0/24 on a single network with Mikrotik router and also have two WAN connections.
network a & network b communicate with each other very fine.
When I want to add routing mark from IP/firewall/mangel to both of the networks for their selected wan routing for WAN1 and WAN2.
Network a & network b stops communication with each other.
if you are going to add routing mark in prerouting. then before it just accept the destination address before marking the routing marks as under.
chain=prerouting action=accept dst-address=10.0.1.0/24
chain=prerouting action=accept dst-address=10.0.2.0/24
then add the marking routes
chain=prerouting action=mark-routing new-routing-mark=ISP1 passthrough=no src-address=10.0.2.0/24 dst-address-type=""
chain=prerouting action=mark-routing new-routing-mark=ISP1 passthrough=no src-address=10.0.1.0/24 dst-address-type=""
How can I configure neutron to allow routing between private networks in the same tenant? When I connect two private subnets with a router, I can't ping instances across the router.
The router isn't enough. You also need to specify a security group rule allowing incoming ICMP packets to the VMs.
It sounds like you need to set the host routes for each network or set the default gateway to be the router that connects the 2 networks.
Default Gateway is used when the host doesn't have any route information for a particular packet. So it will ask the default gateway.
Now for a router there will be lot of static routing information, but if the router is not able to find a routing information, it should take the route mentioned in 0.0.0.0 (which is called default route). Now is this called Default Gateway of a router?
I read few documentation, but i wasn't able to find an accurate definition for Default Gateway wrt router.
It is possible to have a default gateway (typically noted as a route to 0.0.0.0) for a router. It's also known as the "default route".
A typical case for this is where a router has an upstream ISP that it's using for transit to "the rest of the Internet". In this case, the route for 0.0.0.0 would be set to the IP address of the ISP side of your link to the Internet
For example, in the most basic case on a cisco router, if your side of the ISP link is 1.1.1.1 and the "far side" of the ISP link is 1.1.1.2 you'll use something like:
ip route 0.0.0.0 0.0.0.0 1.1.1.2
...to route traffic that doesn't match any other explicit routes in the routing table, out the ISP's interface. The active connection to your ISP installs a route in your routing table, so you know how to get to 1.1.1.2. So if you're trying to get to an external address (say 10.20.30.40), your router is effectively doing two lookups: first it looks up 10.20.30.40 and sees that it should use the default route, which points to 1.1.1.2. It then sees the connected route for 1.1.1.0\30 in the routing table (which contains 1.1.1.2), and then uses that to route the packet.
The default gateway used on on most routers, for the LAN, will be the private IP of the router itself, ex:
IP Address 192.168.5.100
Subnet Mask 255.255.255.0
Gateway 192.168.5.100
Local DNS 192.168.5.100
The default gateway assigned to the WAN port will be assigned by the ISP provider, if the public interface is connected to such. If not connected, you will probably see 0.0.0.0 assigned to the Gateway and other public ip settings.
yes it has, go to command prompt, type ipconfig/all for windows and for mac https://www.expressvpn.com/support/troubleshooting/find-default-gateway/
you can see the default gateway. in accessing it on browser, type https:// and the ip of your router
It's just a simple task:
Open your network and sharing center.
Click on "change adapter setting on your top right"
Right click on the ethernet adapter
Click on properties
Choose configuration
At your right in thee dialog box, there's an option "Enable". Change it to "Disable"
All done now ... Type 192.168.1.1 in your browser
Voila... It works!
