To expand the memory used a flash drive (in my case transcend jetflash 600), I broke the USB flash drive to 3Primary section :

• Linux EXT4 - 256 MB
  
• SWAP - 32 MB
  
• Linux EXT4 - everything else

I have all the necessary configs are found at the root FTP: Network, DHCP, DDNS, Firewall, Wireless, System,fstab . Used a small FTP server, for example Baby FTP Server .

So let's start

1. To start, I updated with firmware fromFrom Yohimba OpenWrt Attitude Adjustment 12.09 (R36088 V5), collected 07.02.2015on the firmware fromGWLIM OpenWrt Barrier Breaker 14.07 (R45620).
   
2. Made a reset of settings (you can do in two ways:
   
   • You can speaking through the terminal by speaking the firstboot command and then restart the router with the reboot command
     
   • You can via the Web interface System>Backup / Flash Firmware->Perform Reset)
   
   
3. An important point, without which you will not be able to enter the router through the SSH terminal,need to install administrator password .
   We go through the Web.http://192.168.1.1System->Administration We enter a password and a password confirmation and clickSave & Apply
   
4. Configure a router manually or in my case I restore the configs from FTP
   Go to the router through the terminalPuTTYAt 192.168.1.1, SSH protocol, port 22.
   We write alternate commands (FTP must be turned on and the configuration files must lie in its root, 192.168.1.100 in my case this address that I assigned a router)
   
   cd / etc / config
   RM Network DHCP DDNS Firewall Wireless
   Wget ftp://192.168.1.100/network
   Wget ftp://192.168.1.100/dhcp
   Wget ftp://192.168.1.100/ddns
   Wget ftp://192.168.1.100/firewall
   Wget ftp://192.168.1.100/wireless
   reboot
   
   
   
5. Restart the PUTTY terminal.
   
   opkg update
   Opkg Install CFDisk E2fsprogs
   mkdir / mnt / sda1
   MKDIR / MNT / SDA3
   Touch / MNT / SDA3 / USB_DISK_NOT_PRESENT
   
   
   
6. We connect the USB flash drive.
   
   
   
7. Connect the Swap section.
   
   mkswap / dev / sda2
   swapon / dev / sda2
   
   
   
8. We re-create the first section of the file system.
   
   MKE2FS -B 4096 -T EXT4 -V -L root / dev / sda1
   
   
   
9. Create a list of UUID sections of the flash drive, we are interested in SDA1 SDA3 sections.
   
   block info>/ etc / config / uuid
   
   
   
10. We go to the router through WinSCP and open / etc / config / uuid and see the following:
    
    
    / dev / mtdblock2: uuid = "59f9547c-70fb4fe1-49f88fc3-25207d37" version = "4.0" type = "SquashFS"
    / dev / mtdblock3: type = "jffs2"
    / dev /sda1 : Uuid = " 73001110-3CF4-4441-872E-C6711A903331. "Label =" root "name =" ext_journal "version =" 1.0 "type =" ext4 "
    / dev / sda2: version = "2" Type = "SWAP"
    / dev /sda3 : Uuid = " F8F7EDBE-1320-CF01-B0B2-EDBE1320CF01 "Label =" sda3 "name =" ext_journal "version =" 1.0 "type =" ext4 "
    
    
    
11. Swing the FSTAB file attached at the bottom, unpack it into the root of your FTP and replace the UUID-s on your SDA1 and SDA3, respectively.
    As a result, it should be like this:
    
    config global
    option anon_swap '0'
    option anon_mount '0'
    option auto_swap '1'
    option auto_mount '1'
    option delay_root '5'
    option check_fs '0'
    
    config mount
    Option UUID '73001110-3CF4-4441-872E-C6711A903331. '
    option enabled '1'
    option device '/ dev / sda1'
    option fstype 'ext4'
    Option Options 'RW, Sync, Noatime, Nodiratime'
    option target '/ overlay'
    
    config swap
    Option Device '/ Dev / SDA2'
    option enabled '1'
    
    config mount
    Option Target '/ MNT / SDA3'
    Option UUID 'F8F7EDBE-1320-CF01-B0B2-EDBE1320CF01 '
    option enabled '1'
    Option Options 'RW, Noatime, Nodiratime, Errors = Remount-Ro, Nouser_xattr, Commit = 100, Barrier = 0, Data = WriteBack'
    Option Device '/ Dev / SDA3'
    option fstype 'ext4'
    
    
    
12. We replace the FSTAB config.
    
    cd / etc / config
    MV FSTAB FSTAB.ORIG.
    Wget ftp://192.168.1.100/fstab.
    /etc/init.d/fstab enable
    mount / dev / sda1 / mnt / sda1
    TAR -C / OVERLAY -CVF -. | TAR -C / MNT / SDA1 -XF -
    reboot
    
    
13. All, Extroot is ready, check, restart the PUTTY terminal.
    
    df -h

    # Select the SubNet topology, allows you to allocate the client / 32 network (in two words each client can be assigned any address from 10.0.0.2 and up to 10.0.0.255, if everything understood everything)
    TOPOLOGY SUNNET.
    
    # Redirect the default gateway to the VPN server
    PUSH "REDIRECT-GATEWAY DEF1"
    
    # We will ask the route that we pass the client and the subnet mask, so that he "saw" the OpenVPN server network
    Push "Route 192.168.1.0 255.255.255.0" # Change This To Your Network
    
    # Indicate the path where files are stored with the customer IP address settings

    Verb 3.
    
    
    
    This is the server configuration fi
    
    On this server settings are completed.
    We proceed to creating customer profiles. I will create a profile in * .ovpn format in which the key and certificates will be inscribed (by the fact that it is more convenient for me to transfer by mail only one client.ovpn file, and not to drag about yet ca.CRT, client.crt, client.key , client.ovpn).
    
    
11. Create keys for customers, depending on how much profiles you need
    
    PKITOOL USER1.
    PKITOOL User2.
    
    I need only 2
    
    
    
    
12. For convenience, a small script was found on the Internet which he himself creates * .OVPN profile
    Via WinSCP go through the way/ ETC / Easy-RSA / Keys And create a file with the name client.sh (create a file by pressing the SHIFT + F4 key) and insert the following lines in advance after the address of your server address under the asterisk:
    
    #! / bin / sh
    [$ # -ne 1] && EXIT 1
    CONF = $ 1.OVPN
    Test -R $ CONF && EXIT 1
    Echo "Client.

    </ key>
    persist tun
    persist-key
    Verb 3 ">$ Pwd / $ conf
    
    
    
    
13. We generate * .ovpn profiles for customers
    through the terminal Putty.
    
    CD / ETC / EASY-RSA / KEYS
    Sh Client.sh User1
    SH Client.sh User2.
    
    
14. Checking whether profiles were created
    
    LS -L * .OVPN
    
    
    
15. Create a CCD folder along the path / etc / openvpn / and the settings of each client will not be stored, in this case, the permanent IP addresses will be
    
    MKDIR -P / ETC / OpenVPN / CCD
    
    
    
    
16. Through WinSCP, create a text file User1 along the way/ ETC / OpenVPN / CCD
    
    IFCONFIG-PUSH 10.0.0.2 255.255.255.0
    
    
    
    
17. Through WinSCP, create a USER2 text file on the way/ ETC / OpenVPN / CCD
    
    IFCONFIG-PUSH 10.0.0.3 255.255.255.0
    
    
    
    
18. Turn on OpenVPN and put it in autoload.
    
    /etc/init.d/openvpn enable
    /etc/init.d/openvpn start
    
    
    If everything is fine, then through WinSCP on the way/ ETC / Easy-RSA / Keys Copy my user1.ovpn and user2.ovpn computer.
    Now, for example, copy one of the profiles on the Android phone, install the OpenVPN CONNECT client, import the profile and check.
