VPN IPSEC traffic not routing to subnets/vlans outside of the firewall's network

[iamcx]

I have an IPSEC VPN setup between our data center and our AWS cloud network. The VPN connection is up and I can communicate from my AWS cloud computers to any devices on the subnet of the firewall (192.168.2.0/24). The firewall has a default gateway of 192.168.2.1 that routes traffic to/from our other networks (192.168.3.0, 192.168.4.0, etc.). Traffic from the VPN cannot talk to anything outside of the 192.168.2.0 network. I was assuming the VPN IPSEC traffic would follow the default gateway to get out, but it doesn't. I'm assuming I need to configure some other routes, but not sure how to get this done. Any help would be appreciated.
