PIX behind Cisco 1841 - need SSH access

Hello, trying to enable SSH access to PIX for some external host clinets.

What are the correct Acl I need?

Exactly correct...

1 - on the router, you must allow incoming TCP 22 (ssh) to your PIX on the external interface of the router and also allow the flow back of the PIX inside interface of the router.

2. - to the PIX you must generate rsa keys and save them.

CA generates the key rsa 1024

CA save all

3 - on the pix you will need to allow ssh acccess to you outside of the interface

SSH outdoors

Write it down if you find it useful

  • SSH access to PIX

    Hello

    I have a PIX 515. I set up SSH access to the external interface. But if I access denied with connection error.

    Invalid message type

    I set up a user name with privileg password all. Siftware is Version 6.2.

    Access with PDM works very well.

    someone an idea?

    Thank you

    First of all you have todo the foillowing

    hostname XXXXXXXX

    Domain XXXXXXXX

    passwd XXXXXXX (this is the password used to authenticate Telnet / SSH)

    Then, you create a pair of RSA keys

    CA generates the key rsa 512 (check this command you can have fun with levels of encryption, that is to say 512 or 1204)

    Allow ssh hosts/networks to your PIX

    SSH #ip address or network # #subnet mask # #interface #.

    FOR EXAMPLE

    If my external IP address my 1.1.1.1 and I needed to access your pix, you will need to enter the following command

    SSH 1.1.1.1 255.255.255.255 outside

    If you get the prompt for a user name try pix, I use software very good LSVCCs of terminal.

    Thank you

  • WRVS4400n (SSH access) port forwarding

    I have a WRVS4400n and a Server CentOS that I need to access SSH from WAN.

    I've created a single port rule to forward to open port 22 and pass to the server (whose address is 192.168.41.3)

    However ssh connect can't, 'ssh user@{external_IP}' command times out after 20 seconds.

    I was wondering why...

    If I connect to my server directly to the modem through the external interface - I have a problem to connect to it. Once, it is behind the router - no luck.

    I even added same rule for UDP, don't know if it's necessary, but it did not really hepl.

    The router is on the version of the firmware 2.0.1.3, on a background version is 2.

    Any suggestions?

    Centre,

    The server does not respond to the front port is because if the traffic is unknown to this subnet it is not sent to the address 41.1 looks. If you can not ping any what other subnet, then the local LAN subnet on the server you will not be able to communicate with a public IP or even a PC via a VPN tunnel, address because the destination IP address is outside the LAN subnet. The reason to ask if the server can ping internet.

    Is it possible to remove the default gateway on the eth0 interface, just in case it is causing problems with the statements of the route on the server.

    What is a linux server?  If yes you can run the command-line - n to see what looks like your routing table?

    Yes, you need a VPN site-to site. Start with this link which gives a number of examples to set up a VPN S2S between 2 routers Cisco.

But if I try this address outside the local access network, then it works fine?

    My other problem I have is that I would like to setup 7 vpn which all dial for this router. They are configured to use ipsec with a preshared key ike. The dial of the router are vigor 2600-2820 series and I was going to use the following configuration to the cisco but it crashes card crypto cm-cryptomap.

    Cryptography works fine it seems.

    The error you receive is I think because that side vigor is able to encrypt a subnet ip (range) that is not defined by Cisco.

    The force he sends down to Cisco and after decrypting the Security Association IPSEC is a fall because it does not part of interesting traffic.

    But, I guess you're already running.

  • L2l VPN with NAT static to hide the IP internal on Cisco 1841 ISR

    I configured a VPN L2L on a Cisco 1841 ISR.  I'm statically from some of my internal hosts to IPS that are included in encrypted traffic.  Please note that not all internal hosts are underway using a NAT.  I am doing this for hidden some of the actual IP addresses on the inside network.  I confirmed that the VPN works as well as natives of VPN traffic.  I configured VPN L2L traditionally on the Cisco ASA 5500 Series devices, and this is my first attempt with HIA of 1841.  I want just the other to take a glance to see if I missed something, or could I effectively part of the configuration.  All comments are welcome.

  • SRW2048 and a Cisco 1841

    I am trying to Setup VLAN between a 2 and a Cisco 1841 router SRW2048 switches. I have ports that connect the 2 switches to the other and the port that connect to router as junction ports. I set 2 VLANS. VLAN 1 is just the vlan by default everyone runs and vlan will be the area demilitarized. I have no configuration of access control lists to block traffic, but when I assign vlan 2 on the port that the server is, I can not ping to the gateway. I don't know what is happening, see below for the cleaned configs.

    SRW2048 #1:

    Port 1: Trunk (to the router)

    Port 2: Trunk (SRW2048 #2)

    Prot 24: VLAN 2

    SRW2048 #2:

    Port 1: Trunk (of SRW2048 #1)

    Any ideas?

    Because the SRW is now part of Cisco Small Business, it would probably be best to ask the Cisco Small Business support community. You find people from Cisco over there.

    For SRW configuration, you added the two VLANS to your trunk ports? Configuration of a port in trunk mode adds automatically that all configured VLAN to the trunk.

    The server has a static IP address in the DMZ LAN?

  • -Cisco 1841

    Howdy,

    I have a Cisco 1841 with two WAN ports to use 0/FE0 FE 0/1

    First FE 0/0 has an MPLS connection with my internet provider. 2MB / 2MB DL/UL

    Second FE 0/1 has a MPLS internal with one of our server's storage providers. 1 MB / 1 MB DL/UL

    The thing is, I have a second Wired internet connection in a router low cost for emergencies. I want to centralize all services in the 1841.

    It is possible to configure the port for a third connection ADSL and load balancing between ADSL1 (FE 0/0) and ADSL2 (future port to THE) 2MB / 2 MB DL/UL

    ( ? )

    Or need another router?

    Thanks in advance,

    Kind regards

    Hi Miguel,.

    You will need the WIC-1ADSL for the WAN connection extra said.

    The port to THE is usually connected to an external modem for remote management.

  • Change of SG 200-18 - management - VLAN / telnet/ssh-access?

    Hello

    We have a switch SG200-18 that should be used as a switch of working group in our environment (SW

    Version 1.1.1.8). In collaboration with CLI on big and mid range Cisco gear during the past two decades, I have a hard time to understand what follows on the SG200:

    (o) I want to change the management VLAN by default '1' to the management - VLAN used in our environment. Of course, I created this vlan in SG200-config, however when it comes to assign the management IP and VLAN management interface in the advancement of the corresponding film under "Interface IPv4-> management VLAN" selectable is the default "1". see screenshots (closed)

    So, how to define a management VLAN 1 different?

    (o) how to enable telnet/ssh-access the SG200-18 - I'd be much more comfortable with a CLI environment ;-)

    Thank you very much in advance for your help,.

    -ewald

    Hello Ewald,

    Sx200 series switch does not currently offer a CLI option. Have this feature if the Sx300 and 500 series.

    What about chaning the vlan management, you have two options.

    (1) changes the vlan by default under management VLAN > Default vlan settings. This will change all the ports and the management vlan.

    (2) adds a port as a port untagged in the new VLAN. Once this is done, make sure that something is connected to this port, like a computer. Now you should be able to change the vlan management. (This is done to prevent locking)

  • How to use Layer 2 Ports on the Cisco 1841 router switch

    Hello

    I use the Cisco 1841 router with a single port layer 3 Fe0 and 8 Ports switched.

    I gave the IP on the Fe0 port which is connected to another router.

    Now I don't know how to use Layer 2 of the router switch ports.

    I tried to make one of the port as a Port of access by switchport mode access and connected my laptop and the same subnet given IP, but I can't ping my Fe0 IP port and vice versa, as I am also unable to ping my laptop router.

    Can someone explain to me how to use these ports on layer 2?

  • Client VPN Cisco ASA 5505 Cisco 1841 router

    Hello. I'm doing a connection during a cisco vpn client and a vpn on one server asa 5505 behind a 1841 router (internet adsl2 + and NAT router).

    My topology is almost as follows

    customer - tunnel - 1841 - ASA - PC

    ASA is the endpoint vpn (outside interface) device. I forward udp port 500 and 4500 on my router to the ASA and the tunnel rises. I exempt nat'ting on the asa and the router to the IP in dhcp vpn pool. I can connect to my tunnel but I can't "see" anything in the internal network. I allowed all traffic from the outside inwards buy from the ip vpn pool and I still send packets through the tunnel and I get nothing. I take a look at the statistics on the vpn client and I 2597 bytes (ping traffic) and there are no bytes. Any idea?

    Where you you logged in when you took the "crypto ipsec to show his"? If this isn't the case then try again, also this option allows IPSEC over UDP 4500 and it is disabled, enable it.

    ISAKMP nat-traversal crypto

    Just enter the command as it is, then try to connect again after activation of this option and get the same result to see the.

  • Cisco 1841 and a connection in fiber optics 400MbS

    Cisco 1841 is a router 100mbs.

    The building has a line of 400mbps.

    My question is can I connect Cisco 1841 to a line of 400mps directly without configuration or hardware changes for 400mps?  We only need a line 100mps output.  Trying to avoid a new router when not not required.

    Thank you

    Brendon

    The 1941 will be fine.  Note that a 891F is likely to be cheaper and will have almost identical performance and comes with all licenses (whereas licenses are an 'extra' for the 1941).

    I almost stopped sale of 1941 as a result.

  • Cisco 1841 match filter by string http requests

    I have a web server behind a Cisco 1841 router that receives a lot of requests like follows(DDOS Slowloris), which causes the resource consumption of bandwidth and the server:

    "POST/WP - login.php HTTP1.1".

    On the web server, I managed using Iptables to stop these requests, but now I want to move this task to the Cisco 1841 router so that such requests stops at the front door and don't go all the way to the web server.

    How can it be implemented in the Cisco firewall so that any request matching the string "POST/WP - login.php HTTP1.1" had to be abandoned?

    Hello

    Theres two ways to do that would work on a 1841 you can try anyway

  • How to Setup Cisco 1841 as a site to site VPN VPN server, with watch guard

    I would like to implement a cisco 1841 as a VPN server to establish s IP VPN (site to another) of a watch guard firewall,.

    I have looked through some examples of cisco config, but can't seem to get a lot.

    Can you please send me sample config steps I need o perform on the cisco router? and what credentials must be awarded to watch keeps establishing a permanent VPN?

    emergency assistance will be greatly appreciated.

    The cisco router is configured as a lan to lan normal IPSEC tunnel, there is no difference when configuration to create a tunnel to a watchguard/sonicwall or all that peer will use, you can use this link as a guide:

    Hello

    According to this output is more than clear that you do not have a k9 license applied to this router, this license will enable the security features on your IOS, in this case, you will need a permit of k9 with an activation key, and then you will be able to have available on your device encryption controls. Once you have that we can work on configuring site to site.
