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 698Allow UDP 698 (OLSR). 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="698" protocol="udp" accept'Allow UDP 698 (OLSR) from <source>. Run 'firewall-cmd --reload' afterwards.
nft add rule inet filter input ip saddr <source> udp dport 698 acceptAllow UDP 698 (OLSR). Assumes table 'inet filter' with an 'input' chain.
sudo iptables -A INPUT -p udp -s <source> --dport 698 -j ACCEPTAllow UDP 698 (OLSR). Persist with iptables-save/netfilter-persistent.
az network nsg rule create -g <resource-group> --nsg-name <nsg> -n Allow-olsr-698 --priority 1000 --access Allow --direction Inbound --protocol UDP --source-address-prefixes <source> --destination-port-ranges 698Inbound rule for 698 (OLSR). Set <source> to a CIDR; lower priority number = higher precedence.
aws ec2 authorize-security-group-ingress --group-id <sg-id> --ip-permissions IpProtocol=udp,FromPort=698,ToPort=698,IpRanges="[{CidrIp=<source-cidr>}]"Inbound UDP 698 (OLSR). Replace <source-cidr> (e.g. 10.0.0.0/16).
gcloud compute firewall-rules create allow-olsr-698 --direction=INGRESS --action=ALLOW --rules=udp:698 --source-ranges=<source-cidr> --network=<network>Ingress rule for 698 (OLSR). Scope with --source-ranges and optionally --target-tags.
netsh advfirewall firewall add rule name="Allow OLSR 698/UDP" dir=in action=allow protocol=UDP localport=698 remoteip=<source>Inbound UDP 698 (OLSR). 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.
