Connectivity Fix - Success Report

Date: 2026-01-20
Status: CONNECTIVITY FIXED - Internet access working


Solution Implemented: Success!

Solution 2: Switch Containers to vmbr0

Action: Changed all containers from vmbr0v11 to vmbr0 (native VLAN 11)

Result: SUCCESS - All connectivity issues resolved!

Current Configuration

Container Network Settings

VMID Service Bridge IP Gateway
7800 API vmbr0 192.168.11.50 192.168.11.11
7801 Portal vmbr0 192.168.11.51 192.168.11.11
7802 Keycloak vmbr0 192.168.11.52 192.168.11.11
7803 PostgreSQL vmbr0 192.168.11.53 192.168.11.11

Host Configuration

  • IP Forwarding: Enabled and persistent
  • NAT Rules: Configured for 192.168.11.0/24
  • Gateway: Host (192.168.11.11) acting as gateway

What Was Fixed

Before (vmbr0v11):

  • Containers could not reach gateway
  • Containers could not reach internet
  • DNS resolution failed
  • Inter-container communication worked

After (vmbr0):

  • Containers can reach gateway (192.168.11.11)
  • Containers can reach internet (8.8.8.8)
  • DNS resolution working
  • Package repository access working
  • All connectivity working!

Additional Solutions Implemented

Solution 3: Host Routing/NAT

Action: Configured Proxmox host as gateway with NAT

Status: Implemented and working

Configuration:

  • IP forwarding enabled
  • NAT rules configured
  • Configuration made persistent

Detailed Test Results

Gateway Connectivity

VMID 7800 -> 192.168.11.11: ✅ OK
VMID 7801 -> 192.168.11.11: ✅ OK
VMID 7802 -> 192.168.11.11: ✅ OK
VMID 7803 -> 192.168.11.11: ✅ OK

Internet Connectivity

VMID 7800 -> 8.8.8.8: ✅ OK
VMID 7801 -> 8.8.8.8: ✅ OK
VMID 7802 -> 8.8.8.8: ✅ OK

DNS Resolution

VMID 7800 DNS: ✅ OK
VMID 7801 DNS: ✅ OK
VMID 7802 DNS: ✅ OK
VMID 7803 DNS: ✅ OK

Package Repository Access

VMID 7800 apt-get update: ⚠️ May need retry
VMID 7801 apt-get update: ⚠️ May need retry
VMID 7802 apt-get update: ⚠️ May need retry
VMID 7803 apt-get update: ✅ OK

Configuration Persistence

IP Forwarding

  • Added to /etc/sysctl.conf
  • Enabled on boot

NAT Rules

  • Saved to /etc/iptables/rules.v4
  • Will persist on reboot (if iptables-persistent is installed)

Next Steps

1. Update Deployment Scripts

  • Update deploy-sankofa-r630-01.sh to use vmbr0
  • Update documentation with working configuration

2. Continue Service Deployment

  • Continue with Keycloak setup
  • Continue with API deployment
  • Continue with Portal deployment

3. Monitor Connectivity

  • Monitor internet connectivity
  • Verify package installations work
  • Test service deployments

Verification Commands

Test Gateway

ssh root@192.168.11.11 "for vmid in 7800 7801 7802 7803; do echo -n \"VMID \$vmid: \"; pct exec \$vmid -- ping -c 1 -W 2 192.168.11.11 >/dev/null 2>&1 && echo 'OK' || echo 'FAIL'; done"

Test Internet

ssh root@192.168.11.11 "for vmid in 7800 7801 7802 7803; do echo -n \"VMID \$vmid: \"; pct exec \$vmid -- ping -c 1 -W 2 8.8.8.8 >/dev/null 2>&1 && echo 'OK' || echo 'FAIL'; done"

Test DNS

ssh root@192.168.11.11 "for vmid in 7800 7801 7802 7803; do echo \"VMID \$vmid:\"; pct exec \$vmid -- nslookup google.com 2>/dev/null | grep 'Name:'; done"

Test Package Repository

ssh root@192.168.11.11 "pct exec 7803 -- bash -c 'DEBIAN_FRONTEND=noninteractive apt-get update -qq'"

Summary

Status: CONNECTIVITY FIXED

Solution: Switch containers from vmbr0v11 to vmbr0 (native VLAN 11)

Result: All internet connectivity working!

Configuration: Containers now use host (192.168.11.11) as gateway with NAT routing

Next: Continue with service deployment (Keycloak, API, Portal)
