Routing between two subnets
Posted: Fri Jan 06, 2012 3:04 pm
Hallo together,
here is my current situation:
Subnet 1 - 192.168.0.0/24 connected to RB750GL via ether2 with IP 192.168.0.254
Subnet 1 has an Gigabit Switch with other clients, this Switch is connected to RB750GL with ether2.
Subnet 1 has a DSL Router for Internet access (IP 192.168.0.240) by ISP 1.
Subnet 1 gateway is 192.168.0.254.
Subnet 2 - 192.168.128.0/24 connected to RB750GL via ether3 with IP 192.168.128.254. The subnets includes only one VM connected to ether3.
Subnet 2 has no switch therefore ether4 is configured as a switch port for the master port ether3.
Subnet 2 has also an DSL Router for internet access (IP 192.168.128.240) by ISP 2. The DSL Router is connected on ether4.
Subnet 2 gateway is 192.168.128.254.
Subnet 1 has internet access via ISP 1. Subnet 2 should use the same ISP.
At the moment I cannot ping between the different subnets.
Ping VM 192.168.128.90 ---> 192.168.128.254 OK connected directly
Ping VM 192.168.128.90 ---> 192.168.128.240 OK connected via ether3/4 switch
Ping VM 192.168.128.90 ---> 192.168.0.254 OK both interfaces are part of same routerboard
Ping VM 192.168.128.90 ---> 192.168.0.240 FAILS!
Ping VM 192.168.128.90 ---> google.de FAILS! but DNS can be resolved to IP
Tracerout sends all packets to the correct gateway 192.168.128.254 but from there nothing is going on.
Is there missing any route between the subnets?
Here is the /ip route print output:
0 A S 0.0.0.0/0 192.168.0.240 1
1 ADC 192.168.0.0/24 192.168.0.254 ether2-local-ma... 0
2 ADC 192.168.128.0/24 192.168.128.254 ether3-local-ma... 0
No firewalls are set.
Any advices? Thanks, toby
