Im have ASA firewall 5520, there outside and inside ports where im using private IP address on them. The traffic is directed to another external firewall (Firebox), means that im I have default route goes throughout outside:
#route outside 0.0.0.0 0.0.0.0 10.10.30.1 1
The problem is that I want to use one if the available ASA ports to make VPN connection, I attached this port (2) directly to my ISP router and assigned a public IP address, then I assumed this port needs default router/NAT/ACL to add.
When I add the default route it gives me this error:
#route vpn 0.0.0.0 0.0.0.0 41.x.x.x 1
#ERROR: Cannot add route entry, conflict with existing routes
Could anybody explain to me why im getting this error, and if my config is the right one for this scenario
