# Allow Web Traffic

If your outbound traffic is restricted and you need to allow outbound `ICMP
ECHO REPLY` traffic, you can achieve this by adding a specific outbound rule to
your Exoscale Security Group. This guide will help you configure the rule to
permit `ICMP Type ECHO REPLY (type 0)` with no code, ensuring proper ping
functionality.

## Steps to Allow Outbound Reply

1. **Access the Exoscale Portal**
  - Log in to your Exoscale account.
  - Navigate to the **Compute** section and access your instance.

2. **Select Security Group**
  - From your instance details, locate the **Security Group** settings.
  - Choose the relevant security group to which your instance is attached. This is the group where you'll add the outbound rule.

3. **Configure Outbound Rule**
  - Within the selected Security Group, go to the **Outbound Rules** section.
  - Click on the **Add Rule** button to begin creating a new outbound rule.

4. **Specify ICMP Protocol**
  - In the protocol selection, choose `ICMP`.
  - Set the Type to `ECHO REPLY (type 0)`.
  - Leave the code field as `NO CODE` since no specific code is required for this ICMP type.

5. **Restrict Destination (Optional)**
  - If desired, specify a destination IP address or network range to restrict which IPs can receive outbound ECHO REPLY messages. By default, this will be open to all.

6. **Save the Rule**
  - After configuring the rule parameters, click on **ADD** to save the changes.
  - Allow some time for the changes to take effect and propagate through your instance setup.

7. **Verification**
  - Test your configuration by performing a ping operation from an internal service or monitoring tool. The outbound ICMP ECHO REPLY responses should now be successful.
