TCP Yes
UDP
SCTP
DCCP

What it is

Internet Small Computer Systems Interface storage protocol (RFC 3720).

When / why

Block storage over IP. Commonly seen on 3260 in practice; isolate on a storage network.

Protocol status detail

TransportStatusMeaning
TCP Yes Assigned by IANA and standardized, specified, or widely used on this port.
UDP Not applicable for this transport.
SCTP Not applicable for this transport.
DCCP Not applicable for this transport.

Port range

Well-known (0–1023). System port for a core service. On Unix-like systems, binding it requires superuser privileges.

Firewall rules for port 860

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 860

Allow TCP 860 (iSCSI). 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="860" protocol="tcp" accept'

Allow TCP 860 (iSCSI) from <source>. Run 'firewall-cmd --reload' afterwards.

nftables

nft add rule inet filter input ip saddr <source> tcp dport 860 accept

Allow TCP 860 (iSCSI). Assumes table 'inet filter' with an 'input' chain.

iptables

sudo iptables -A INPUT -p tcp -s <source> --dport 860 -j ACCEPT

Allow TCP 860 (iSCSI). Persist with iptables-save/netfilter-persistent.

Azure NSG

az network nsg rule create -g <resource-group> --nsg-name <nsg> -n Allow-iscsi-860 --priority 1000 --access Allow --direction Inbound --protocol TCP --source-address-prefixes <source> --destination-port-ranges 860

Inbound rule for 860 (iSCSI). 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=860,ToPort=860,IpRanges="[{CidrIp=<source-cidr>}]"

Inbound TCP 860 (iSCSI). Replace <source-cidr> (e.g. 10.0.0.0/16).

GCP firewall

gcloud compute firewall-rules create allow-iscsi-860 --direction=INGRESS --action=ALLOW --rules=tcp:860 --source-ranges=<source-cidr> --network=<network>

Ingress rule for 860 (iSCSI). Scope with --source-ranges and optionally --target-tags.

Windows netsh

netsh advfirewall firewall add rule name="Allow iSCSI 860/TCP" dir=in action=allow protocol=TCP localport=860 remoteip=<source>

Inbound TCP 860 (iSCSI). Set remoteip to a host/subnet; 'any' is discouraged.

Windows PowerShell

New-NetFirewallRule -DisplayName "Allow iSCSI 860/TCP" -Direction Inbound -Action Allow -Protocol TCP -LocalPort 860 -RemoteAddress <source>

Inbound TCP 860 (iSCSI). 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.
