Hello, in my home lab, I have a Cisco 871W named cants. I connected cants to my BT (ISP) router (BT.homeblahblah) using the wan link f 4, then I created a vlan 2 and assign it to por f1 on the 871 router. Im unable to ping from that vlan to router 192.168.1.254 which is my bt router.
Please see my config file:

Now when I try to ping from a laptop connected using a cable to f 1 I get request timed out. Also when I try to pring from the router, nothing:
cants#ping 192.168.1.254 source 172.18.0.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.254, timeout is 2 seconds:
Packet sent with a source address of 172.18.0.1
.....
Success rate is 0 percent (0/5)
I hope I have given enough information, but please let me know if you need more. I understand the the basics how vlan advertise themselves, I understand the basics of routing, thats why I created 192.168.1.254 (BT router) as my last resort default gateway, so that everything can go there if no other route given.
Many thanks in advance.
