Open BGP port on bastion node SG - #83975
Conversation
when running the BGP and EVPN workloads we need the BGP port 179 needs to be opened in the Bastion node to make the connection from worker to BGP server running on the Bastion, this PR enables the port 179
WalkthroughThe bastion provisioning commands now allow inbound TCP traffic on port 179 for both IPv4 and IPv6 security groups. ChangesBastion BGP ingress
Estimated code review effort: 1 (Trivial) | ~3 minutes Merge Risk: 🟡 Moderate · up to The change opens BGP port 179 to all IPv4 and IPv6 sources instead of limiting access to worker nodes, unnecessarily expanding the bastion’s attack surface. Restrict the rule to the required worker sources, or obtain explicit security-owner acceptance before merging. 🚥 Pre-merge checks | ✅ 15✅ Passed checks (15 passed)

Restrict TCP port 179 to worker-node sources.
The security groups allow all IPv4 and IPv6 sources through TCP port 179. If only worker nodes require BGP access, use worker-node CIDRs or the appropriate source security group for both address families.

Summary by CodeRabbit
The bastion host security group now allows inbound TCP traffic on port 179 for IPv4 and IPv6. This enables worker nodes running BGP and EVPN workloads to connect to the bastion host’s BGP server.
