I'm having troubles routing from two VLANs on Cisco Router here is the config:
interface FastEthernet0/1.13
encapsulation dot1Q 13
ip address 192.168.13.254 255.255.255.0
ip nat inside
no ip virtual-reassembly
!
interface FastEthernet0/1.21
encapsulation dot1Q 21
ip address 10.10.10.29 255.255.255.0
ip nat outside
no ip virtual-reassembly
!
And the routing part:
ip forward-protocol nd
ip route 0.0.0.0 0.0.0.0 <ISP GW IP>
ip route 10.10.5.0 255.255.255.0 10.10.10.90
There are other things going one on the router, specially a big access list and also a lot of NAT's but nothing related with this VLANs.
If I'm on a VLAN 13 host and try to ping for instance a VLAN21 Address shouldn't it work?
EDIT #1
Result of sh ip route
Gateway of last resort is <ISP GW> to network 0.0.0.0
