A user reports that they can access the internet but cannot reach a server on a different subnet (192.168.10.0/24). The user's IP is 192.168.1.50/24 with a default gateway of 192.168.1.1. You ping the gateway successfully, but ping to 192.168.10.10 fails. What should you check next?

The routing table on the default gateway.
