PS4 Remote Play

Common Ways To Remote Play While Away Home

1. The official PS Remote Play app away home play feature
   I'm currently using v6プラス(based on MAP-E) option from my ISP. I have public IPv4/v6 addresses but I have only SOME IPv4 ports available. I failed to connect my PS4.

2. The official PS Remote Play app in-home play feature with a home VPN server
   This method works on OSI-layer 2 VPN but not on layer 3.
   WireGuard is layer 3. And I have no plan to start a OpenVPN TAP mode (layer 2) VPN.

The solution (the third way to remote play)

Prepare a layer 3 home VPN server.

Use Chiaki instead of official PS Remote Play. (I learned here)

Seems Chiaki don't wake PS4 on LAN. So I installed ps4-waker on my home Raspberry Pi.

Just follow the link and setup it.

The result

0. Set PS4 to Rest Mode before leave home. (Don't Power Off)
1. SSH into home Raspberry Pi.
2. Run ps4-waker command will wake up PS4.
3. Connect to home VPN (layer 3).
4. Open Chiaki any enjoy it.

Block Country IPs

Tutorial for how to boycott CN IPv4 on OpenWrt.
Script from here https://github.com/kravietz/blacklist-scripts
CIDR IP list from my project https://country-ip-blocks.hackinggate.com

OpenWrt Setup

Install

opkg install ipset curl
wget https://raw.githubusercontent.com/kravietz/blacklist-scripts/master/blacklist.sh
mv blacklist.sh /etc/firewall.user

Create /etc/ip-blacklist.conf

URLS="https://country-ip-blocks.hackinggate.com/CN_IPv4.txt"

Edit /etc/firewall.user

I don't have pppoe-wan and the blocklist don't work.
I replaced IN_OPT="-i $wan_iface" with IN_OPT="" and it works now. (kravietz/blacklist-scripts#6)

Activate

# Manual run
sh /etc/firewall.user
# Daily update
echo "01 01 * * * sh /etc/firewall.user" >>/etc/crontabs/root

Check & Test

ipset list -name

Two new sets are added

manual-blacklist
country-ip-blocks.hac

View blocked CN IPv4 entries

ipset list country-ip-blocks.hac

Here's how to use manual-blacklist.

ipset add manual-blacklist 8.8.8.8
ipset list manual-blacklist
ping 8.8.8.8
ipset del manual-blacklist 8.8.8.8
ping 8.8.8.8

Block Multi Lists

Example of /etc/ip-blacklist.conf

# Emerging Threats lists offensive IPs such as botnet command servers
URLS="https://rules.emergingthreats.net/fwrules/emerging-Block-IPs.txt"

# Blocklist.de collects reports from fail2ban probes, listing password brute-forces, scanners and other offenders
URLS="$URLS https://www.blocklist.de/downloads/export-ips_all.txt"

URLS="$URLS https://country-ip-blocks.hackinggate.com/CN_IPv4.txt"
URLS="$URLS https://country-ip-blocks.hackinggate.com/HK_IPv4.txt"
URLS="$URLS https://country-ip-blocks.hackinggate.com/MO_IPv4.txt"

All set will name country-ip-blocks.hac and override.

To fix it. Edit /etc/firewall.user. Insert script between the two lines. L116

# download the blocklist                                                                                            
set_name=$(echo "$url" | awk -F/ '{print substr($3,0,21);}') # set name is derived from source URL hostname         
curl -L -v -s ${COMPRESS_OPT} -k "$url" >"${unsorted_blocklist}" 2>"${headers}"     

Will be

# download the blocklist                                                                                            
set_name=$(echo "$url" | awk -F/ '{print substr($3,0,21);}') # set name is derived from source URL hostname         
# autodetect country-ip-blocks.hackinggate.com                                                                      
if echo "${url}" | grep -q 'country-ip-blocks.hackinggate.com'; then                                                
    set_name=$(echo "$url" | awk -F/ '{print substr($4,0,21);}')                                                    
fi                                                                                                                  
curl -L -v -s ${COMPRESS_OPT} -k "$url" >"${unsorted_blocklist}" 2>"${headers}"     

sh /etc/firewall.user and ipset list -name will be

manual-blacklist
rules.emergingthreats
www.blocklist.de
CN_IPv4.txt
HK_IPv4.txt
MO_IPv4.txt

Check if there's entries

ipset list CN_IPv4.txt | wc -l
