Re: Is there any way to choose an ISPs default gateway
The tunnel default gateway is needed to let the internal firewall and router handle the routing for all decrypted IPsec packets. Today, after a Cisco IOS? EasyVPN Client connects to a Cisco IOS EasyVPN Server, there is no simple way for the client to send the tunnel traffic to the internal corporate network (other than to have the entire routing table on the IPsec gateway). In this type of implementation, the Cisco IOS routers use the default gateway to route all packets toward the Internet that do not have a more specific route. The tunnel default gateway gives customers the flexibility to control how they handle IPsec tunneled traffic
