Telia network degredation / POC
by Jeremy Chadwick 02 Jun '06

02 Jun '06

Does anyone have a contact number/POC of any sort for Telia that's within the United States? Jared's NOC list only contains a contact number in Sweden. It seems their network has been falling apart both within Sweden and the US since the raid on TPB (ThePirateBay.org) earlier today. Sure, it's probably kiddies as usual, but this is pretty major. Can anyone confirm/deny?

Cisco ACL question
by Jon R. Kibler 01 Jun '06

01 Jun '06

Greetings All, Sorry for the slightly off-topic question, but I suspect that this is an issue that others have faced or may soon face as ISP continue to push out more PPP-oriented networks. One of our customer's ISP is converting from static IP assignments to PPP IP assignments for all customers' Internet facing routers. This is creating a security problem that I do not know how to fix and for which the ISP is no help. Problem: how to ACL on a dynamic IP? Assume that we have the following (partial) configuration on a Cisco 2801 and are assigned the static netblock 1.2.3.0/29. This was what worked before the ISP made the change. ! Old config example interface serial0/2/0 ip address 1.2.3.1 255.255.255.248 ip nat outside ip access-group 110 in ... interface fastethernet0/0 ip address 172.17.100.254 255.255.255.0 ip nat inside ... ip nat pool localstatic 1.2.3.2 1.2.3.2 prefix 29 ip nat inside source list 1 pool localstatic overload ip nat inside source static tcp 172.17.100.22 22 1.2.3.5 12322 ip nat inside source static ... access-list 1 permit 172.17.100.0 0.0.0.255 access-list 1 deny any log access-list 110 permit tcp any 1.2.3.0 0.0.0.7 established access-list 110 permit tcp host a.b.c.d host 1.2.3.5 eq 12322 access-list 110 deny tcp any any log access-list 110 permit udp host d.n.s.1 eq 53 host 1.2.3.2 access-list 110 permit udp host d.n.s.1 host 1.2.3.2 eq 53 access-list 110 permit udp host n.t.p.1 eq 123 1.2.3.2 access-list 110 deny udp any any log access-list 110 permit icmp any host 1.2.3.2 echo-reply access-list 110 permit icmp any host 1.2.3.2 unreachable access-list 110 permit icmp any host 1.2.3.2 time-exceeded access-list 110 deny icmp any any log access-list 110 deny ip any any log In the new configuration, the serial0/2/0 interface now has a dynamic IP. How can I put ACLs on that IP that will permit NTP, DNS, and ICMP originating from within the router to work? Everything behind the router works, but anything generated by the router itself breaks (because the external IP is not permitted in an ACL). In the new configuration, this is the only change I made (other than PPP stuff): ! New config example interface serial0/2/0 ip address negotiated ip nat outside ip access-group 110 in ... Everything from behind the router continues to work fine. However, the router is unable to do NS lookups, set time, etc. Basically, all traffic to the dynamic IP is blocked. Is there a SIMPLE way to fix this problem AND keep the router secured? I have searched the Cisco site, and Google, and cannot seem to find an answer that I can fully comprehend. I thought that maybe 'ip nat outside' was my fix, but I could not get it to do what I expected. Thanks in advance for your help! Jon Kibler -- Jon R. Kibler Chief Technical Officer A.S.E.T., Inc.

Control Plane Policing
by hjan 01 Jun '06

Hello, I have read cisco's doc about cpp and i've also read the good documentation written by John Kristoff about cpp in wich are included some implementation example. I do some test in our lab environment, a GSR 12410 with IOS 12.0(32)S2 but i'm not satisfied with the result. Suppose this sample conf: access-list 168 permit icmp any loopback0 0.0.0.0 access-list 169 permit any class-map cp-icmp match access-group 168 class-map cp-default match access-group 169 policy-map cp-traffic class cp-icmp police 8000 conform-action transmit exceed-action drop class cp-default priority control-plane service-policy input cp-traffic Then i ping from a host or a router the loopback0 and i noticed that only if i set an MTU or packet size > 1500, in fact 1480 so with the standar ip header is always 1500, the policy take effect. In fact if i issue the sh policy-map control-plane with small packet size all traffic seems to be matched by the cp-default class: Service-policy input: cp-traffic (225) Class-map: cp-icmp (match-all) (4925921/1) 0 packets, 0 bytes 5 minute offered rate 0 bps, drop rate 0 bps Match: access-group 168 (15210210) police: cir 8000 bps, bc 4470 bytes conformed 0 packets, 0 bytes; actions: transmit exceeded 0 packets, 0 bytes; actions: drop conformed 0 bps, exceed 0 bps Class-map: cp-default (match-all) (14530241/2) 151 packets, 11967 bytes 5 minute offered rate 2000 bps, drop rate 0 bps Match: access-group 3 (1872818) Class-map: class-default (match-any) (9318433/0) 3149 packets, 333931 bytes 5 minute offered rate 1000 bps, drop rate 0 bps Match: any (4397474) Instead with a greater size: Class-map: cp-icmp (match-all) (4925921/1) 22 packets, 16896 bytes 5 minute offered rate 2000 bps, drop rate 0 bps Match: access-group 168 (15210210) police: cir 8000 bps, bc 4470 bytes conformed 20 packets, 13888 bytes; actions: transmit exceeded 2 packets, 3008 bytes; actions: drop conformed 2000 bps, exceed 0 bps Is there anyone with some idea or anyone that can share experience with me ? Thanks Gianluca Italy
