I see your internal networks are on .1x and 2x subnets. Try adding "route inside 192.168.0.0 255.255.0.0 Gateway" to see if that works. If that does not not work, pls. post your router and switch configs.

Do you have internal subnets 192.168.3.x, 192.168.5.x, 192.168.15.x? If you do, your VPN IP ranges are in conflict with the internal networks. Try reducing the range and ensure that you've proper routing in place for those subnets.
