Adding new subnet

[Kahlaoui1980]

Hello everyb ,
I have a network with addressing 10.142.0.0 , and i have one new proxy to connect to my network with the following parameters
new subnet 10.70.25.176 /30
* Proxy eth With address 10.70.25.178
* the interface in the swith must have the address 10.70.25.177

Here is what i did in the switch and Router

SWITCH 3560

interface FastEthernet1/0/41
switchport access vlan 1070
switchport mode access

ROUTER CONFIGURATION
interface GigabitEthernet0/1.1070
encapsulation dot1Q 1070
ip address 10.70.25.177 255.255.255.240

network 10.70.25.176 0.0.0.15 area 0

but no connexion , we can ping the switch interface (10.70.25.177 ) but not the proxy lan (10.70.25.178 )
does any one have an idea

1) your config looks like you want to use a /28 and not a /30 as you state. double-check your masks all around and make sure they are correct
2) make sure that the proxy is using .177 as its gateway

can you detail the topology?? it is a 3560 plugging into a router and you're using a router-on-a-stick config??

You can ping the subinterface...from where? What is the status of the interface in the 3560 that the proxy is plugged into (sh int)? Post a complete config of the router and switch, including where things are plugged into (router plugged into what port of the switch, proxy plugged into what port of the switch, and the sh int results from al these ports).

Also, post a sh ip route
