Firewall rules for port 9080

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 9080

Allow TCP 9080 (WebSphere HTTP). Replace <source> with the network/host that should reach it.

sudo ufw allow proto udp from <source> to any port 9080

Allow UDP 9080 (WebSphere HTTP). 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="9080" protocol="tcp" accept'

Allow TCP 9080 (WebSphere HTTP) from <source>. Run 'firewall-cmd --reload' afterwards.

sudo firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="<source>" port port="9080" protocol="udp" accept'

Allow UDP 9080 (WebSphere HTTP) from <source>. Run 'firewall-cmd --reload' afterwards.

nftables

nft add rule inet filter input ip saddr <source> tcp dport 9080 accept

Allow TCP 9080 (WebSphere HTTP). Assumes table 'inet filter' with an 'input' chain.

nft add rule inet filter input ip saddr <source> udp dport 9080 accept

Allow UDP 9080 (WebSphere HTTP). Assumes table 'inet filter' with an 'input' chain.

iptables

sudo iptables -A INPUT -p tcp -s <source> --dport 9080 -j ACCEPT

Allow TCP 9080 (WebSphere HTTP). Persist with iptables-save/netfilter-persistent.

sudo iptables -A INPUT -p udp -s <source> --dport 9080 -j ACCEPT

Allow UDP 9080 (WebSphere HTTP). Persist with iptables-save/netfilter-persistent.

Azure NSG

az network nsg rule create -g <resource-group> --nsg-name <nsg> -n Allow-webspherehttp-9080 --priority 1000 --access Allow --direction Inbound --protocol "*" --source-address-prefixes <source> --destination-port-ranges 9080

Inbound rule for 9080 (WebSphere HTTP). 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=9080,ToPort=9080,IpRanges="[{CidrIp=<source-cidr>}]"

Inbound TCP 9080 (WebSphere HTTP). Replace <source-cidr> (e.g. 10.0.0.0/16).

aws ec2 authorize-security-group-ingress --group-id <sg-id> --ip-permissions IpProtocol=udp,FromPort=9080,ToPort=9080,IpRanges="[{CidrIp=<source-cidr>}]"

Inbound UDP 9080 (WebSphere HTTP). Replace <source-cidr> (e.g. 10.0.0.0/16).

GCP firewall

gcloud compute firewall-rules create allow-webspherehttp-9080 --direction=INGRESS --action=ALLOW --rules=tcp:9080,udp:9080 --source-ranges=<source-cidr> --network=<network>

Ingress rule for 9080 (WebSphere HTTP). Scope with --source-ranges and optionally --target-tags.

Windows netsh

netsh advfirewall firewall add rule name="Allow WebSphere HTTP 9080/TCP" dir=in action=allow protocol=TCP localport=9080 remoteip=<source>

Inbound TCP 9080 (WebSphere HTTP). Set remoteip to a host/subnet; 'any' is discouraged.

netsh advfirewall firewall add rule name="Allow WebSphere HTTP 9080/UDP" dir=in action=allow protocol=UDP localport=9080 remoteip=<source>

Inbound UDP 9080 (WebSphere HTTP). Set remoteip to a host/subnet; 'any' is discouraged.

Windows PowerShell

Inbound TCP 9080 (WebSphere HTTP). Replace <source> with a host or subnet.

New-NetFirewallRule -DisplayName "Allow WebSphere HTTP 9080/UDP" -Direction Inbound -Action Allow -Protocol UDP -LocalPort 9080 -RemoteAddress <source>

Inbound UDP 9080 (WebSphere HTTP). 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.
