Routing between /27 and /30 block (VLAN to Physical WAN)

Hello all,

Sorry if this is a mega simple question, but we need to setup something like this: WAN Configuration (generic).jpg

The physical connectivity between the ISP network and External Switch 1 i.e. the /30 network is on port GigabitEthernet 0/19. The /27 network is configured as VLAN100. How do we configure such that all hosts in the 192.168.1.64/27 network can access the Internet using the .66 HSRP IP. Then of course we can configure routing in the Firewall to allow hosts in the internal network to access the internet too. But that's another story.

Help please?

Thanks so much in Advance

If you can ping it after removing /30 block, then certainly it's an issue on your ISP side as you've already discovered.

Alas, nothing was wrong with our configuration. The ISP hadn't setup stuff at their end correctly. When they did, it all started to work fine.

Thanks for keeping company Roman
