Copy-ready inbound rules for the active transports. Replace every <source> placeholder with the specific host, subnet, or CIDR that should reach this port.
sudo ufw allow proto udp from <source> to any port 434Allow UDP 434 (Mobile IP agent). Replace <source> with the network/host that should reach it.
sudo firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="<source>" port port="434" protocol="udp" accept'Allow UDP 434 (Mobile IP agent) from <source>. Run 'firewall-cmd --reload' afterwards.
nft add rule inet filter input ip saddr <source> udp dport 434 acceptAllow UDP 434 (Mobile IP agent). Assumes table 'inet filter' with an 'input' chain.
sudo iptables -A INPUT -p udp -s <source> --dport 434 -j ACCEPTAllow UDP 434 (Mobile IP agent). Persist with iptables-save/netfilter-persistent.

Set <source> to a CIDR; lower priority number = higher precedence.

gcloud compute firewall-rules create allow-mobileipagent-434 --direction=INGRESS --action=ALLOW --rules=udp:434 --source-ranges=<source-cidr> --network=<network>Ingress rule for 434 (Mobile IP agent). Scope with --source-ranges and optionally --target-tags.
netsh advfirewall firewall add rule name="Allow Mobile IP agent 434/UDP" dir=in action=allow protocol=UDP localport=434 remoteip=<source>Inbound UDP 434 (Mobile IP agent). Set remoteip to a host/subnet; 'any' is discouraged.

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.
