hi guys
i want to ping via mikrotik box set as a router, but can’t work.
client ---------------- eth1 mikrotik eth2 ---------------------------- cisco
192.168.10.1/30 -------- 192.168.10.2/30 (eth1) 192.168.10.253/30 (eth2) ------------- 192.168.10.254 (cisco)
in mikrotik route : /ip route add gateway=192.168.10.254
the client can’t ping the cisco router via mikrotik. why ??
please help !!
Does the client have a default route to 192.168.10.2?
Does the Cisco also have a /30 netmask?
Best regards,
Christian Meis
What default Gateways have you put?
You dont have to tell the Mikrotik Router about the networks because its directly attched to both.
BUT,
the cisco router doesnt know the clients network and the client doesnt know the cisco network.
try add in the cisco, a route that points to the mikrotik for the client network whole slash /30
then add on the client either a default 0.0.0.0/0 to the mikrotik or a route to point to the mikrotik that shows the cisco network
BTW also check your firewall rules to make sure youare allowing ICMP packets
thanks for the fast replay
client ------ eth1 mikrotik eth2 -------- cisco
this is the configuration :
client : 192.168.10.1
netmask : 255.255.255.252
gateway : 192.168.10.2
mikrotik eth1
ip : 192.168.10.2
netmask : 255.255.255.252
eth2
ip : 192.168.10.253/30
netmask : 255.255.255.252
/ip route add gateway=192.168.10.254
cisco :
ip eth : 192.168.10.254
netmask : 255.255.255.252
ip serial : 192.168.100.2
netmask : 255.255.255.252
ip route 0.0.0.0 0.0.0.0 192.168.100.1
no firewall added in all the router and client.
client still can’t ping cisco via mikrotik, why …
Then it probably is the missing route on the Cisco…

i put this in the cisco router
ip route 0.0.0.0 0.0.0.0 192.168.100.1
but the client still can’t ping cisco
it’s look like mikrotik can not pass connection from client to cisco
Hai,
Gimana kopi lampungnya masih banyak ga', kalo masih kirim donk ke gue, karena udah lama kagak menikmatinya. tentang buat route anda bisa buat dengan single interface atau lebih, seingat gue kalo double interface sebaiknya IPnya bedakan saja satu dengan yang lainya. pasti ok.....
gue juga punya yang single interface[NIC] tapi bisa membuat banyak sesuai kebutuhan anda. dan sekarang saya sedang membangun yang baru dengan 3 pisik [NIC]. maklumlah gue disini juga masih perlu belajar banyak.... dan kondisi sekarang semuanya juga sedang running....untuk jaringan local dan luar local juga webserver.
in english plzz 
You need to configure a route in the Cisco telling it to reach the subnet 192.168.10.0/30 over gateway 192.168.10.253!

can u give me an example ?
Sorry, CMIT
can you continue to him... one focus point from you is better.
i will go to dinner now
Sorry, no Cisco guy 
Have thrown out the last Cisco years ago.
But should be something like
ip route 192.168.10.0 255.255.255.252 192.168.10.253
or the like…
Don’t you have a reference manual for the Cisco?

hi cmit
i ever expect like that too, i must put client route in cisco. but… it’s not work.
this problem makes me try other network configurations take the cisco off and put a ms wondows PC:
client 1 (MS windows) ----- eth1 mikrotik eth2 ------- client 2 (MS windows)
client 1 (MS windows)
ip : 192.168.10.1
netmask : 255.255.255.252
gateway 192.168.10.2
mikrotik
ip eth1 : 192.168.10.2
netmask : 255.255.255.252
ip eth2 : 192.168.10.253
netmask 255.255.255.252
/ip route add gateway=192.168.10.254
client 2 (ms windows)
ip : 192.168.10.254
netmask : 255.255.255.252
client 1 still can’t ping client 2
it’s look like it can’t passthough mikrotik box
So now your Windows client (replacing the Cisco) must have a route to the subnet of client1 (or its’ default route to the MikroTik)…

oh
i see… i’ll try it first… thanks
client 1 (MS windows) ----- eth1 mikrotik eth2 ------- client 2 (MS windows)
client 1 (MS windows)
ip : 192.168.10.1
netmask : 255.255.255.252
gateway 192.168.10.2
mikrotik
ip eth1 : 192.168.10.2
netmask : 255.255.255.252
ip eth2 : 192.168.10.253
netmask 255.255.255.252
/ip route add gateway=192.168.10.254
client 2 (ms windows)
ip : 192.168.10.254
netmask : 255.255.255.252
gateway : 192.168.10.253
can we make client 2 ping client 1 trough mikrotik box without adding an extra route to client 1 ?
i mean all route is handle by mikrotik.
client 1 using IP Private .
client 1 using IP private.
i think u need add nat (src nat) from client A in your MT box.
From client 1, can you ping mikrotik ip eth2 first?
I think this is a simple routing, all client have same gateway device with diferent ip.
Mikrotik can do it without adding any rule like Linux system with ip_forward = 1.
