CS network ACL summary

---

work in progress -- please send comments to trg

---

We've requested a summary (with regular ongoing updates and maintenance) of the ACLs applied to our networks by the constituency routers for our area. See our ST#90052, which refers to the IST RT UW-RT #302304 (which you probably won't be able to read). These are both stalled indefinitely (as of 2014-2-28).

In the interim, here is an informal and likely incomplete summary:

client networks

• outbound unrestricted
• off-campus inbound restricted, other that stateful return traffic
• networks affected:

IP adresses	Router	Vlan
129.97.84.0/24	dc-cs2	84
129.97.168.0/24	dc-cs2	168
129.97.169.0/24	dc-cs2	169
129.97.170.0/23	dc-cs2	170

Each of the above networks is restricted to "outbound" traffic only, with a couple of exceptions. The ACL is stateful with respect to established TCP connections -- ie the traffic that comes back as the result of an outbound TCP connection is allowed. The exceptions which allow inbound traffic are for:

• ssh
• RDP
• ident

For details, see the dc-cs2 configuration definition of the ACL set "170_client-untrust"

infrastructure LOM/IPMI networks

• outbound unrestricted (notwithstanding private IP limitations)
• off-campus inbound restricted
• intra-campus inbound restricted
• networks affected:

IP adresses	Router	Vlan
10.0.152.0/24	dc-cs2	525
10.0.153.0/24	cs-rt-dc-2303a	525
10.0.154.0/24	cs-rt-mc-3015a	525
10.0.155.0/24	cs-rt-m3-3101	525
10.15.2.0/24	dc-cs2	802
10.15.3.0/24	mc-cs2	806
10.15.16.0/24	dc-cs2	816
10.15.18.0/24	dc-cs2	812
10.15.28.0/24	mc-cs2	810

Each of the above networks can be reached only from the following networks/hosts:

IP adresses	Comment
10.15.152.4/32	Host: asgard.cscf.uwaterloo.ca
129.97.15.0/24	CSCF network
172.19.15.0/24	CSCF trusted UW-Intranet network -- not implement yet at of 2014-3-6
172.19.4.229/32	Host: cscf.cs.uwaterloo.ca

research LOM/IPMI

As at 2014-3-6, there is one dedicated research LOM network, namely 172.19.96.0/24. It is completely unrestricted. It it proposed to expand this to three separate network, as follows:

Network	vlan	Comment
172.19.96.0/24	1896	existing network, unrestricted access
172.19.97.0/24	1894	high-restricted LOMs, just from vlan 15 and cscf.cs.uwaterloo.ca; same as the infrastructure LOMs
172.19.98.0/24	1895	moderately-restricted, allows various client networks within CS, as follows:
		129.97.7.0/24	research servers
		129.97.15.0/24	CSCF staff network
		129.97.26.0/24	research servers
		129.97.84.0/24	client workstations
		129.97.105.0/24	Shoshin research group
		129.97.114.0/24	CGL research group
		129.97.167.128/25	CS public servers (contains linux.cs) (vlan dc:421)
		129.97.168.0/24	client workstations
		129.97.169.0/24	client workstations
		129.97.170.0/23	client workstations
		129.97.173.192/26	CSG research group (vlan dc:1732)
		129.97.186.0/24	PLG research group
		172.19.15.0/24	CSCF Staff network -- future

teaching-lab networks

• outbound unstricted
• off-campus inbound restricted (except for stateful TCP)
• some intra-campus inbound restricted, eg wireless and ResNet unless otherwise noted

IP adresses	Router	Vlan	Comment
129.97.51.0/24	mc-cs2	51	Mac labs in MC
129.97.173.64/26	mc-cs2	424	ugsters, allows ssh, RDP, ident; allows wireless

infrastructure general-purpose networks
