NAT Router configuration

• NAT Router is Ubiquiti Networks "Edge Router 4"

• NAT Router has been configured (by Larry@LIGO GC) through the GUI interface, which is only available from the martian network. To launch the GUI interface, simply access to the martian IP of the router (192.168.113.2) with a web browser. You can find the user name and password at the usual secret place. User Name: 40Mubnt Password: ll@cit_admin_ubnt

• Open ports:

  • 22 (ssh) - port forwarded to nodus
  • 873 (rsync) - port forwarded to nodus
  • 8080/8081 (elogd) - port forwarded to nodus
  • 30889 (apache) - port forwarded to nodus
  • 31200 (NDS) - port forwarded to megatron
  • 22220 (ssh) - port forwarded to port 22 on c1teststand for direct ssh access.

• Along with the NAT router installation, firewall rule of the shorewall on nodus was turned off as it is no longer necessary. We still neet to keep shorewall itself running to open the specified ports. The WAN (GC net) side cable of nodus was removed. NodusShorewallSetting
