Response to DANM on CISCO ASA 5510 configuration
Step1: Configure a privileged level password (enable password)
By default there is no password for accessing the ASA firewall, so the first step before doing anything else is to configure a privileged level password, which will be needed to allow subsequent access to the appliance. Configure this under Configuration Mode:
ASA5510(config)# enable password mysecretpassword
Step2: Configure the public outside interface
ASA5510(config)# interface Ethernet0/0
ASA5510(config-if)# nameif outside
ASA5510(config-if)# security-level 0
ASA5510(config-if)# ip address 100.100.100.1 255.255.255.252
ASA5510(config-if)# no shut
Step3: Configure the trusted internal interface
ASA5510(config)# interface Ethernet0/1
ASA5510(config-if)# nameif inside
ASA5510(config-if)# security-level 100
ASA5510(config-if)# ip address 192.168.10.1 255.255.255.0
ASA5510(config-if)# no shut
Step 4: Configure PAT on the outside interface
ASA5510(config)# global (outside) 1 interface
ASA5510(config)# nat (inside) 1 0.0.0.0 0.0.0.0
Step 5: Configure Default Route towards the ISP (assume default gateway is 100.100.100.2)
ASA5510(config)# route outside 0.0.0.0 0.0.0.0 100.100.100.2 1
Step 6: Configure the firewall to assign internal IP and DNS address to hosts using DHCP
ASA5510(config)# dhcpd dns 200.200.200.10
ASA5510(config)# dhcpd address 192.168.10.10-192.168.10.200 inside
ASA5510(config)# dhcpd enable inside
The above basic configuration is just the beginning for making the appliance operational. There are many more configuration features that you need to implement to increase the security of your network, such as Static and Dynamic NAT, Access Control Lists to control traffic flow, DMZ zones, VPN etc.
BTW I pulled this info from another site.. I was just toooo lazy to type it all out myself:-)

Thanks for the info. I will try it out and see if I can access the internet through the ASA.

With a good Wi-Fi router, there are several ways to control internet access, both at home and at the office. Not only can you control who can access the internet from your router, you can also block websites, limit the hours of access, throttle bandwidth and even block rogue access points from hijacking your network. Although the administrative options on a router vary with different models and manufacturers, usually, the best place to start is to look for the router's parental controls. Yes, even routers designed for small businesses have parental controls, so controlling internet access at home is often the same as controlling it at work.
Accessing Admin Controls
Router control is accessed using the Administrative Panel of your router, which is available through a web browser, or an app issued by the manufacturer. Some Netgear routers, for example, can only use a mobile app, while Linksys business routers can usually be accessed by typing 'http://business.linksys.com/' into a web browser connected to your network. Older routers can be accessed by typing the router's IP address in a web browser, such as '192.168.0.1' or something similar.
How to Control Wi-Fi Usage
The best way to stop someone from accessing the internet through your Wi-Fi is to prevent them from logging in through your router. This begins by setting a strong password (i.e. long, with no discernible words in it) and WPA2 encryption. You can also disable SSID Broadcast, which stops your router from announcing itself to anyone searching for a signal.
A more time-consuming, but very effective, method is to block access to all devices except those you list in the router's access control settings. Computers, tablets and smartphones all have a unique identifier, which is hardwired into the device by the manufacturer. It's called the physical address, or MAC address.
This can be time consuming, if you have a lot of computers or a high-turnover of employees in your office. To find the physical address of a Windows PC, open the Command Prompt, type 'ipconfig /all' and press Enter.
Enabling Guest Access
A common method of controlling use of your internet access is to first enable Guest access on the router. This is ideal for coffee shops or for any other business that may have many people using your Wi-Fi for short periods of time. Essentially, a guest network is a separate network that's made so you can set up restrictions for guests but that will not affect your employees.
For example, you can change the password daily or you can use other tools, such as throttling bandwidth to ensure that guests don't take advantage of your service. Employees, on their own network, would be unaffected. J s institute coaching bengaluru karnataka. An added security benefit is that a guest network keeps employee computers inaccessible to your guests.
Enabling Internet Filters
If employees are spending too many hours on social media and on YouTube, you may want to consider blocking these websites on your router, if that option is available. You should also review your security options and look for internet filters that prevent anyone on the internet from trying to probe weaknesses in your network. For example, a common filter is to block Port 133 on the router from outside queries.
Restricting Hours of Usage
Most routers with parental controls give you an option to limit internet access to specific hours. All playable races in d&d 5e. If your company is open only during business hours, you may want to consider blocking all internet access at night and on weekends.

Throttling Bandwidth Usage
Cisco Restricting Access To The Internet Speed
Throttling bandwidth usage doesn't prevent anyone from accessing the internet, but it does slow them down. If your router gives you this option, just drag the slider to an appropriate level. This may take some trial and error, so try the half-way mark and test it on a few websites and then adjust it, as needed. You should be able to access most websites quickly enough, but downloading movies or playing online video games will be much slower and more difficult to do.

Hello,
As you can see by these screenshots, the VPN connection to the remote network works. I have an address from the VPN pool and everything. The default gateway is set correctly. Yet, I cannot reach the internet and I cannot ssh/ping anything in the same subnet except the VPN adapter which is 10.0.0.231(first IP address in VPN pool). I don't have a default-gateway assigned for some reason.
I have no idea why this is happening. I am currently using my hotspot so I can make sure it works before trying to VPN from a network far away. I don't know how to assign a default gateway, I am looking at asdm.
