There is discussion of network changes related to adding new subnets for Galaxy at bxa:Network/Galaxy which should be relevant should you need to add a new subnet.

Layer 2

Current network diagram in DIA format is located at /afs/bx.psu.edu/admin/documents/bx_network-l2-<DATE>.dia

When updating, be sure to work on a copy, and update the date in the box in the upper left-hand corner.

  • Broadcast: 172.18.2.255
  • Gateway: 172.18.2.1

  • DNS: dot1x-128-118-202-N.bx.psu.edu

PAT Address | 128.118.202.254

PAT = Port Address Translation. This is similar to how SNAT works with iptables. A single public ip. This is preferred to just straight NAT, which on the ASA is one-to-one with a set translation expiration time. After the global IP range is used up, further outbound connections are dropped. A single PAT address supports up to 65,536 outbound connections (TCP sessions).

NAT config on ASA: 

global (Outside) 1 128.118.202.254
nat (Bioinformatics) 1 192.168.2.0 255.255.255.0
nat (Bioinformatics) 1 192.168.4.0 255.255.255.0
nat (Bioinformatics) 1 10.1.0.0 255.255.0.0

Dynamically assigned with DHCP. 802.1x EAP-TTLS-PAP username/password login.

VLAN 120 | UNMANAGED | 128.118.202.0 /25, 2610:8:7800:29:: /64

  • VLAN: 120 (UNMANAGED)
  • Netmask: 255.255.255.128
  • Broadcast: 128.118.202.127
  • Gateway: 128.118.202.1
  • DNS: custom or 128-118-202-N.bx.psu.edu

Statically assgined with DHCP based on MAC. Radius attributes defined in LDAP for the DHCP host entry.


VLAN 130 | GUEST | ?

  • VLAN: 130 (GUEST)
  • DNS: guest-128-118-202-N.bx.psu.edu

DHCP entries static in LDAP. Web authorization form to allow changing of the MAC address, restricted to PIs and other persons of repute. These entries will be periodically expired. Or, tie into EDUROAM somehow?

Not sure what addresses GUEST will use, or if it will be NAT'd.

VLAN 140 | GALAXY_PUBLIC | 128.118.79.224 /27

  • VLAN: 140 (BX-WIRED)
  • Netmask: 255.255.255.224
  • Broadcast: 128.118.79.255
  • Gateway: 128.118.79.225

Galaxy public addresses. This network can route on the XSEDE network via switch-dell-powerconnect-1.

VLAN 500 | RCC_P2P | 10.128.255.240/29

  • VLAN: 500 (RCC_P2P)
  • Netmask 255.255.255.248

Point to point with RCC.

switch-dell-powerconnect-1: 

interface vlan 500

  • VLAN: 510 (CISCO_DELL_P2P)
  • Netmask 255.255.255.248

cisco vlan 510 : 10.1.7.1 dell vlan 510 : 10.1.7.2
