hello everyone I am setting up a network I had two mikrotik routers one is the main(mikrotik 1) and secondary router (mikrotik 2). Mikrotik 1 is having dhcp client ether 3 taking everyone information from dhcp. both routers are connected to each other on ether 1 and with the ip address of 192.168.199.1/24 on mikrotik 1 and 192.168.199.2/24 on mikrotik 2. I am trying to run pppoe on mikrotik ethernet 2 but I cannot ping mikrotik 1 default gateway that is acting as default gateway for the network.
I tried creating static routes everything I know of I tried but it did not work
All replies are appreciated!!
Thanks
This config always works good. And for [mikrotik2]> ping 192.168.199.1 will work too.
[mikrotik2]> ping mikrotik1_default_gateway will work only if nat enabled. Don't forget reset configuration after last test.

I have two routers:
Router A
Router B
Router A is the primary router and B is the one with lowest priority in HSRP.
What I did was to configure 3 subinterfaces with encapsulation dot1 to assign them to a VLAN.
Everything is clear to me up to this point:
I want to have a DHCP pool for each VLAN, I used the HSRP virtual IP as the gateway, but I configured DHCP exactly the same on routers A and B. I have an itch that says me even tough it works on packet tracer, it is not a correct configuration, due to having 2 DHCP servers on the same network. Is my itch correct or this is how is supposed to work?
Thank you for your answers!
I'm writing to you because I can't solve a problem with a client.
My client has an infrastructure with the following characteristics:
2 ISP routers
1 fortigate firewall
1 dedicated router that broadcasts a UCOPIA US250 guest portal
65 Zyxel switches (1900 - 24) and one 4600 switch (4x 24 ports for the core network)
250 WIFI LIGOWAZE NFT terminals
80 VLANs
I do not manage the first 3 equipments, it is another provider.
Today, I have to pass the VLAN dedicated to the guests.
The other provider has set up the FORTIGATE to broadcast the DHCP and the associated VLAN on the DMZ port to the OUT port of the UCOPIA.
I have to broadcast VLAN 420 from the IN port to the ZYXEL switch and to the LIGOWAVE terminals.
However, when I am connected to the UCOPIA on the IN port, I manage to get the desired IP and to reach the portal, but when I test on the ZYXEL switch, it is impossible to get the dedicated VLAN.
I put myself on another port of the ZYXEL, I TAG the VLAN in question. I have modified the ID of my VLAN on my computer in DHCP that does not work. I tried to use static IP but still nothing. I can't even ping the gateway.
The ZYXEL port to which the UCOPIA is connected is TAGGED on the dedicated VLAN. I have also tried Untagged and excluding all the other VLANs but it is impossible to get this network.
Do you have any other ideas for me?
Here, you can see my diagram network:
MyNetwork
I resolved my problem.
I configured Switch like that:
Untagged dedicated VLAN
But i forgot to change the PVID VLAN.
I changed it and that work !
Hello Everyone!
I want to know that is there any way to access a photocopier machine which is connected to a computer through Ethernet wire and that computer is connected to my WiFi network?
P.S: What if I don't know the IP assigned to that Photocopier machine?
If the wireless network is part of the wired network you should have any problem reaching the photocopier.
If you don't know the IP address, you can reach it by host name if the DHCP and DNS are working properly. If you are on an Active Directory infrastructure and DHCP and DNS are integrated it should be transparent.
If you are on your home with a "home" router they usually do the hostname to IP resolve (DNS).
You can nslookup hostname in your machine to see if your dns is resolving the ip address. you can also ping hostname or ping ip address to test that you can reach the desired host. Some hosts block ping (ICMP) requests, please note that ping is ping does not respond is not a definitive solution.
Please note that in your home router you should use your router or default gateway to be the DNS also, and then add the google public DNS or your ISP.
Also when connecting the access point to an existing network you may have 2 DHCP servers providing IP addresses to hosts, you should disable DHCP on the Access Point and connect the AP to the network using the switch port and not the WAN port (the WAN port will try to do NAT and assign a different set of IP addresses).
This is an easy solution, I just don't have it, so please help!
I have 6 Ruckus R500 WAP, connected into 2 Cisco SG300's, which are then connected to FortiGate 200D.
On the WAP, I have 5 SSID, one of which is set to VLAN 2.
The ports which the WAP connect to on the SG300's have VLAN 2 added to them, trunk mode.
In the FortiGate200D:
All ports are in LAN HW Switch.
IP: 10.3.7.210/255.255.252.0
DHCP 10.3.4.1-10.3.5.254
I have a VLAN sub created on the LAN, with an Id of 2.
IP: 10.3.9.1/255.255.255.0
DHCP 10.3.9.2-254
There are "auto" routes created for 10.3.9.0/24 --> 0.0.0.0
When I connect to the VLAN 2 SSID, I am unable to pull an IP. If I set static IP, I am unable to ping. Where am I messed up? Is it because my LAN HW Switch subnet does not contain 10.3.9.xxx ? What would the best way to overcome this be, perhaps change LAN HW Switch to 10.3.0.0/21?
Basically the end goal is 10.3.4.0 and 10.3.5.0 for normal connections. And then a separate subnet for VLAN2, could be 10.3.8.0 or 10.3.9.0 or whatever, even 192.168.1.0.
This was solved by Zac67. I had to correct tagging, then open up traffic to WAN and DHCP kicked in just fine. Thanks Zac67
we have a few problems trying to setup a network, we will try to explain what we got.
These are the devices that we have:
-ISP #1 modem
-ISP #2 modem
-Cisco Router 4331
-Cisco Firewall 5508
-Some switches
-An internal DNS Server and a few PC’s
Network topology
You can see the network diagram (the diagram is just to illustrate the topology).
Actual status
-The ISP #1 modem and the ISP #2 modem assign DHCP as show in images
-The Router can ping to ISP #1 modem and ISP #2 modem
-The Router can ping to google.com through ISP #1 modem and through ISP #2 modem
-The Firewall can’t ping to any ISP modem or google.com
-The PC’s can’t ping any ISP modem or google.com
-This link contains a shared folder with attached files (https://1drv.ms/f/s!AqkJyrRRfKHigetLlyGFtQ8RX_RpKg)
Edit:
Everything was solved by deleting the default network option!
Are you sure the firewall the default gateway set to the router (192.168.4.247)?
It looks like PCs have the firewall as default gateway, which is correct. Also, the router has default routes as part of the DHCP negotiation with ISP#1 and ISP#2 modems. But nothing shows that the firewall knows where to send non-local packets.
Hope it helps!
