sudo ufw allow proto tcp from <source> to any port 2427

Allow TCP 2427 (MGCP gateway). 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="2427" protocol="tcp" accept'

Allow TCP 2427 (MGCP gateway) from <source>. Run 'firewall-cmd --reload' afterwards.

nftables

nft add rule inet filter input ip saddr <source> tcp dport 2427 accept

Allow TCP 2427 (MGCP gateway). Assumes table 'inet filter' with an 'input' chain.

Azure NSG

az network nsg rule create -g <resource-group> --nsg-name <nsg> -n Allow-mgcpgateway-2427 --priority 1000 --access Allow --direction Inbound --protocol TCP --source-address-prefixes <source> --destination-port-ranges 2427

Inbound rule for 2427 (MGCP gateway). 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=2427,ToPort=2427,IpRanges="[{CidrIp=<source-cidr>}]"

Inbound TCP 2427 (MGCP gateway). Replace <source-cidr> (e.g. 10.0.0.0/16).

GCP firewall

gcloud compute firewall-rules create allow-mgcpgateway-2427 --direction=INGRESS --action=ALLOW --rules=tcp:2427 --source-ranges=<source-cidr> --network=<network>

Ingress rule for 2427 (MGCP gateway). Scope with --source-ranges and optionally --target-tags.

Windows netsh

netsh advfirewall firewall add rule name="Allow MGCP gateway 2427/TCP" dir=in action=allow protocol=TCP localport=2427 remoteip=<source>

Inbound TCP 2427 (MGCP gateway). Set remoteip to a host/subnet; 'any' is discouraged.

Windows PowerShell

New-NetFirewallRule -DisplayName "Allow MGCP gateway 2427/TCP" -Direction Inbound -Action Allow -Protocol TCP -LocalPort 2427 -RemoteAddress <source>

Inbound TCP 2427 (MGCP gateway). 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.
