eth0 and eth1 config not working

[blunt]

I have two ethernet cards, both connected to the same router. I wanted one of the cards to have IP 192.168.1.10 (eth0) and the other to have 192.168.2.10 (eth1). I can access the server through ssh with both IPs, but if I turn off my eth0 (ifdown) I cannot access the server even with the IP of eth1. I don't understand why...

I will leave my ifconfig output as well as my route output.

Any hel is appreciated...

thank you

I guess it's a routing problem because eth0 and eth1 are in different subnets.
In what subnet is your client PC?

[blunt]

my client PC has subnet 255.255.0.0

[falko]

That's the netmask. What IP address does your client PC have?

[blunt]

sorry i didn't understand your question right.
my client PC address is 192.168.1.236

[falko]

eth1 has 192.168.2.10 which is in a different subnet; that's why you can't connect to it when you disconnect eth0.

[blunt]

is there a way of getting it to work? the problem is that I had eth0 with ip 192.168.1.10 and eth1 with 192.168.1.20.

Then I noticed that even with the eth1 cable unplugged, I could access the server through eth0 with IP 192.168.1.20...when I posted this on another forum, someone told me to give an ip to eth1 from another subnet...

is there another way?
