Firewall rules for port 700

Copy-ready inbound rules for the active transports. Replace every <source> placeholder with the specific host, subnet, or CIDR that should reach this port.

ufw

sudo ufw allow proto tcp from <source> to any port 700

Allow TCP 700 (EPP). Replace <source> with the network/host that should reach it.

firewalld

sudo firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="<source>" port port="700" protocol="tcp" accept'

Allow TCP 700 (EPP) from <source>. Run 'firewall-cmd --reload' afterwards.

nftables

nft add rule inet filter input ip saddr <source> tcp dport 700 accept

Allow TCP 700 (EPP). Assumes table 'inet filter' with an 'input' chain.

iptables

sudo iptables -A INPUT -p tcp -s <source> --dport 700 -j ACCEPT

Allow TCP 700 (EPP). Persist with iptables-save/netfilter-persistent.

Azure NSG

az network nsg rule create -g <resource-group> --nsg-name <nsg> -n Allow-epp-700 --priority 1000 --access Allow --direction Inbound --protocol TCP --source-address-prefixes <source> --destination-port-ranges 700

Inbound rule for 700 (EPP). Set <source> to a CIDR; lower priority number = higher precedence.

AWS Security Group

aws ec2 authorize-security-group-ingress --group-id <sg-id> --ip-permissions IpProtocol=tcp,FromPort=700,ToPort=700,IpRanges="[{CidrIp=<source-cidr>}]"

Inbound TCP 700 (EPP). Replace <source-cidr> (e.g. 10.0.0.0/16).

GCP firewall

gcloud compute firewall-rules create allow-epp-700 --direction=INGRESS --action=ALLOW --rules=tcp:700 --source-ranges=<source-cidr> --network=<network>

Ingress rule for 700 (EPP). Scope with --source-ranges and optionally --target-tags.

Windows netsh

netsh advfirewall firewall add rule name="Allow EPP 700/TCP" dir=in action=allow protocol=TCP localport=700 remoteip=<source>

Inbound TCP 700 (EPP). Set remoteip to a host/subnet; 'any' is discouraged.

Windows PowerShell

New-NetFirewallRule -DisplayName "Allow EPP 700/TCP" -Direction Inbound -Action Allow -Protocol TCP -LocalPort 700 -RemoteAddress <source>

Inbound TCP 700 (EPP). Replace <source> with a host or subnet.

Rules are generated only for transports marked active for this port. They default to an inbound allow with an explicit source placeholder — never any. Review direction, scope, and rule precedence before applying in production.
