Cisco Firewall :: PIX 515e 2 ISPs Max Speed Is Slower With ISP
Apr 19, 2012
have a PIC 515e connected to two ISPs via 2 interfaces. ISP1 is a 3.5Mbps aDSL line, and ISP2 is a 30Mbps business cable. I've confirmed the speeds by connecting the cabled directly into a laptop and using wget to download very large files from known-fast sites.
For admin reasons, I need to access two specific subnets using the slower ISP1. The rest of internet traffic should go to the much faster ISP2.
So I configure ISP2 as the default gateway, static routes for the two subnets to ISP1, set up NAT (PAT) and it all works like a charm. I've confirmed that ISP1 is used for only the two subnets, and ISP2 for everything else. CAPTUREs on the pix also confirm this. So far, it all works great.
But for reasons I don't understand, my max. download speed is 3.5 Mbps (the slow DSL). Using various speed tests and wget, I simply cannot get a download speed faster than my 3.5 Mbps DSL line.
Here is my config:
interface ethernet0 100full
interface ethernet1 100full
interface ethernet2 100full
I have a Cisco PIx firewall that is connected to a cable modem with Time warner cable. I am supposed to have 35 down and 5 up for my speed on that modem. When I bypass the firewall and connect directly to the cable modem, I get download speeds in excess of 30 and upload speeds of about 5. However, when I connect via my workstation, which goes through the PIX, I am lucky to get speeds in the 1.2 for a download and 2-3.5 for the upload. I am using a laptop to test. We have gigabyte Cat5e cabling and gigabyte switches.
Below are statements from the config.The interface lines are per below:
interface ethernet0 100full interface ethernet1 100full interface ethernet2 auto shutdown MTU outside 1500
How can i adjust this so I can make use of the 30 speed of the modem?
I have ATT DSL Extreme service and I actually get about 8.0 service. There is a POTS splitter in my box that splits this line out to my office about 75 feet away. I recently moved the office back into the main residence and rather than move the 8 pair wire ATT put in, I jumped it with a new wire back to my new office. At the POTS, I didn't see where I could add a line so I spliced the pair I needed. Now it essentially feeds either building. But, now my speed tops out at just over 7.0. I have to believe the splice affected the speed but I don't understand why.
I was wondering why are upload speeds so much slower then download speeds with residential IPS. I know downloading is alot more common then uploading something. Does it cost more or something, for the ISP to send information out.
I am getting very slow download speeds on my wireless router (Linksys model#WRT160N). I measured it on speedtest.net. with my ASUS laptop, ASUS Transformer Prime tablet, and 2 Ipod touches. All similar speeds.
Download avg: 1.30 Mbps upload avg: 6.20 Mbps
I measured my desktop speed that is hardwired through the router to the modem.
Download avg: 30.00 Mbps upload ave: 6.20 Mbps
I have scanned all the wireless connection in my area and found them to occupy channels 1, 6, 11. I tried changing my channels one at a time for all 11 channels. Some did a little better than others but not a lot.Also, if I by a dual channel router, can all wireless devices pick up on the 5GHz spectrim and if some, could this alleviate some interference?Is it possible that my router is going bad and a new single channel 2.4 GHz router will be fine?
After changing name and password, the speed became much slower. Checking it with speed test, download is just 0.19 Mbps while upload is 3 Mbps. Wired speed is much better, download is 20 Mbps. So it is not the problem of I provider, comcast. How to solve this problem? I rebooted and reset it already.
Currently we have a T1 for data connected to a 1721 Router that is connected to an ASA 5510. We would like to add a FIOS line for dedicated online backup. Is it possible to connect the FIOS router to the ASA and route the IP from our backup server to use the FIOS line and everyone else continue to use the T1?
Looking to replace an "all-in-one" type firewall (UTM/Firewall, SSL VPN) with a cisco product - the issue i'm running into is that we have multiple ISPs plus WAN and DMZ - overall more than 5 ports on mid-range ASA devices - and from what i read, adding 4-port module precludes me from adding CSC module.
Is there an solution to that other than going for 5585-x model? (kind of over our budget, granted we need 2 for failover)
I have ASA5510 with PLUSE License.I have 2 Inside interfaces as STAFF and MAIL and two Outside interface OUT_STAFF and OUT_MAIL which is in separate ISP's.now i want to nat STAFF to OUT_STAFF and MAIL to OUT_MAILbecause I'm having two default routes it gets impossible to do.
I have a Cisco ASA 5510 and I am trying to set it up to be able to have it failover to the 2nd ISP connection if the 1st one ever went down. I think I need a nat statement that the "backup" connection will use when the 1st connection goes down, but I am unsure what the nat statement is supposed to be. I have added the commands that I am pretty sure that I need to add for the "backup" ISP connection. Attached are those commands, the interfaces that are set up, and the objects that are set up in the ASA.
I inherited a network redesign project mid implementation and ran across an issue that I was not 100% sure able to be resolved. Implementation is occurring in which the organization is changing over to a different ISP and we have some customers that will not be able to change their settings over to our new addresses from some time. I have seen a lot of posts about fail over and dual ISP configurations, but I could not relate them to this particular scenario.
What we are trying to accomplish here use two ISP's (one cable and one T1), use the Cable line for site-to-site VPN and use T1 line for all internet traffic. We currently use the following configuration: Cisco 2820 routers terminating the T1 -> HP switch -> Cisco AS 5510 port 0 -> port 1 to LAN switch (Nortel 5510)We want to force all VPN traffic (using 10.0.0.0/24 subnets - 10.0.1.0, 10.0.2.0, etc) through a cable connection, perhaps on port 2 of the ASA, then all non VPN traffic goes to the T1.
I have an ASA 5505 current f/w & the security plus license (to get the 3 nameif interfaces). Can I split traffic between two ISPs, (VPN traffic to one destination on a T-1 on one VLAN, and all other traffic using DSL to another VLAN) and using a different nat policy on both? I know load balacing isn't supported, only failover. I was just wondering if there was a way to make this work.
I am in the process of configuring a ASA 5510 to replace an older PIX. This change is part of migrating to a new ISP, so the process is complicated by the existence of two outside interfaces. I have virtually everything working, but there is a requirement to be able to access hosts from the internal networks using both their private IPs and their public IPs. The older PIX took care of this silently with little configuration, but the ASA has me twisted on the details. Some of the hosts with public IPs are on the internal network and some are on a DMZ (not my design, inherited). For the internal ones I implemented hairpinning to take care of the requirement, but I am having trouble with the DMZ based hosts.. Since there are two external interfaces each internal host has two IPs and two static NAT rules to handle incoming traffic from each external interface.
The routins and dynamic NAT entries we have in place take care of accessing the hosts using their private IPs on the DMZ, but I cannot figure out how to get the public IPs to work from the internal network. It seems like a simple Static D-Nat shoudl do it, but when I add a Static D-Nat on the DMZ the public IP works, but the private IP breaks.. Is there a way to get them both to operate ?
Network layout looks like this (IP ranges altered):
DMZ 220.127.116.11.0 Class C INTERNAL 10.0.0.0 Class C Outside 18.104.22.168 Class C Outside2 22.214.171.124 Class C
After applying it I could access the public IP (126.96.36.199) from the internal network, but I could no longer access the DMZ IP (188.8.131.52) from the internal network. Is there any way to get this configuration to allow access to both IPs from the internal network ?
The problem here is that there are website links based on the public IP and the DNS is split so DNS returns the internal IP to users. As a result both need to be accessible from the internal network.. Not my favorite design, but the client (or in this case the boss) is always right so I need to get it working somehow.
Looking to have an ASA5510 with two internet feeds. Moreover, I would like to have my static nat translations continue to work on the backup feed. I have outbound nat working, however I cannot get the inbound nat to work. I had this all figured out in 7.x but now with 8.x I cannot seem to get it working. If anyone has a 8.x example config.
I am setting up an ASA550 ver 7.2(3) - does this need upgrading?I have my ISP interfaces setup as primary and backup I have a static route pointing out:route primary 0.0.0.0 0.0.0.0 184.108.40.206 1 Question:Do I put the next static route to be route secondary 0.0.0.0 0.0.0.0 220.127.116.11 254 Will this set a high metric on the secondary route that will only take effect if the primary route is down? I assume I will need to have 2 sets of NAT rules to accommodate the dual ISP's
I need to know if the cisco ASA next generation specially ASA 5515X support PBR or no ?how to implement it? Also if i have many internet connections and i need to dedicate 2 ISP’s ADSL internet lines to certain service (such as mail) if the 1st fail, so the 2nd line come up to make redundancy with it ----------- Is this available on cisco ASA next generation.
Ive got a problem with passing traffic through a Cisco 515e firewall.im trying to telnet to devices on the inside net, 172.16.x.x fom an outside net 10.x.x.x? ive configured a group called infrastructure and added the 10.x.x.x addresses.ive configured acl 101 inbound on the outside interface:
access-list 101 permit tcp object-group INFRASTRUCTURE any eq telnet
when i try and connect, using a packet capture I can see traffic from 10.4.4.34 to the inside device 172.x.x.x on the inside interface but i cant see the traffic leave the outside interface ive used the same group infrastructure group before to connect to VM machines on the 172.x.x.x net on RDP and this wrks ok. access-list 101 permit tcp object-group INFRASTRUCTURE object-group VMs eq 3389
I am trying to set the PIX firewall to transparent mode.After I set it to transparent firewall, I allowed all icmp, tcp, udp traffics.Currently, any devices in the inside network can get the ip automatically from DHCP server in the outside network but cannot ping to any servers in the outside network either access the internet.Do I need additional confiration on the firewall?
Here's the configuration:
PIX Version 7.0(1) firewall transparent names ! interface Ethernet0 [Code]....
I have a PIX 515 Ewhich does authentication for SSH via RADIUS protocol and fails over to the local database if radius server goes offline. But when the radius server comes back online, authentication still takes place through LOCAL and not the radius server. Following are the commands:
\I just configure my PIX 515E with version 7.0(4) and having problems to get traffic out on eth0 (if name outside). There is no problems between different VLAN ,all VLANs are configure on eth1. It is also possible to accass services on VLAN 10 (DMZ) from outside. The only thing I see in syslog is "Built Outbound" and "Teardown".
I have a Pix 515E running PixOS version 8.0.4 with two interfaces, inside and outside.On the inside interface, I have a Redhat Enterprise Linux 5.4 64 bits machine as an NFS server version 4 (NFSv4).On the outside interface, I have three (3) Redhat Enterprise Linux 5.4 64 bits as NFS clients.I am looking for the exact UDP and TCP ports to be added to the ACL in order to accomplish
I need ot upgrade a Cisco PIX 515 E to A Cisco ASA (not sure what type and modle yet!). the PIX currently has about 80 lines of ACLs and no VPNs. So only inside and outside interfaces and 80 lines of ACLs to be transferred over to the ASA.I was wondering if the ACLs can be transferred over to ASA as is?is there anything that I need ot watch for?
