Is there any way to choose an ISPs default gateway


I'm having problems whereby one of my ISPs "gateways" is congested. I'm using an 877 on an ADSL line and I was wondering if there is a way to specify (on the dialer0) interface what gateway to use?

If you look at the output below you will see that after I restart the router (and it picks up a different gateway) the ping times are much improved.

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
