Hosts connected to Vlan1 are not accessible.

[CherVa1941]

I have 877W router.

It is connected to ADSL to the IP-address 1.2.3.4.

To the same address is routed block of IP-adresses 5.6.7.128/15

I configure to Interface Vlan1

IP address 10.0.0.254 255.255.255.0

and

IP address 5.6.7.142 255.255.255.240 secondary

Now access from Internet to all hosts connected to block of IP address (5.6.7.x)are possible.

Access to Internet from network addresses 10.0.0.x and from WiFi are working.

But i cannot access from hosts 5.6.7.x to hosts 10.0.0.x.

Please help me to fix this problem.

Make sure the default gateway on devices with 10.0.0.x is 10.0.0.254

while

devices with 5.6.7.x, default gateway should be 5.6.7.142

Many thanks for your assistance.

I have connected 2 devices the 10.0.0.x network but they was configured for other router.

Unfortunately these devices cannot be configured and i have been compelled to reconfigure CISCO.

You can configure the other router to point to the Cisco router for packets destined to 10.0.0.x

In Cisco, you can accomplish this with:

ip route 10.0.0.x 255.255.255.0 [gateway].
