We've just started with the ASA 5505. We do run a DHCP server on the inside interface, so it is in the same VLAN 1 as all of the clients. However, we cannot get it to work.We can't use DHCP Relay, as the ASA 5505 only allows to relay to DHCP servers in a different subnet.Or do we have to move the DHCP server to a different subnet. If so, how would we configure that scenario?
View 13 RepliesI have a Cisco 5512 x Firewall connected with Cisco Layer 3 switch 3750.I have two different WAN connections, one for Data and one for voice. Cisco Layer 3 switch is configured with 2 different VLAN's one for data & other is Voice Vlan. Switch is providing DHCP to computers and IP phones. Voice Pool 192.168.10.0/24 Vlan10 and Data pool 192.168.20.0/24 Vlan20.I need to route my data & voice traffic separately. Cisco ASA is connected with two different ISP's. So, how can I do this configuration so that Voice and Data traffic will route separately.
View 7 Replies View RelatedI have a Cisco ASA 5505 in our office. We are currently using Interface 0 for outside and 1 for inside. We only have 1 Vlan in our environment. We have two three switches behind the firewall. Today the uplink to Interface 1, to the firewall, on the switch went bad. I want to setup a second inside interface on the firewall and configure it as failover incase this happens again. I want to attach it to the other switch. Can I do this? If so, what do I need to do? would it only be a passive/standby interface?

I have an ASA 5505 that I'm trying to set up a guest network on. I've configured an interface as a trunk and allowed the 2 vlans but I'm not getting any layer 3 to it. The switch connected to it is a 3560 and port is configured as a trunk with the same vlans.
I can't ping the ASA inside interface but I see its MAC address in the swtich's table.

We already have a subnet defined to inside interface and is in produciton. the default gateway is this interface ip. In that setup now I have to add one more subnet and as the first subnet is been defined in ASA indside interface, I have to assign secondary Ip to the inside interface so that new subnet users can easily reach here and go outside.
View 1 Replies View RelatedWe have a Cisco ASA 5505 (v7.2(3)) with a "fairly" normal configuration yet we have a problem where it appears UDP/53 traffic is denied on our inside network.
here is output from our sys log:

To give some clarification:
172.18.22.3 is one of our DNS servers
172.18.22.156 is a device we're experimenting with.
We've bypassed the Cisco by using a 4G wireless router with this same device - and it works flawlessly.Here is a [scrubbed] copy of our config. It is what I inherited from the previous admin - I'm not sure of all its finer points (I'm not Cisco certified -- perhaps I'm just certifiable.)

Trying to add inside routes on an ASA 5505 to point traffic to another gateway for other connected networks is resulting in the following error 6Sep 16200 819:13:5810601510.184.236.1265003810.170.54.1823389Deny TCP (no connection) from 10.184.236.126/50038 to 10.170.54.182/3389 flags RST on interface insideI believe the problem is due to the Asymetric tcp connection and the ASA is dropping the connection because it only see one half of the traffic.Is there a way we can stop the firewall dropping the TCP connections on the inside interface? i've tried removing the threat managment which didnt work.Annoying thing is were putting the ASA 5505's in to replace old Watchguard soho firewalls only the watchguards forwarded the traffic no problem at all.

My internal network consists of Catalyst 3750 switches segmented into different VLANs. There is a default route on the layer 3 Catalyst switch sending all unknown traffice to the inside Internet of the ASA 5510. However, I'd like to have a separate VLAN for wifi guest access and send all of that traffic through one of the DMZ interfaces on the ASA 5510. I don't think you can have separate default routes based on VLANs on the 3750 switches so my only option is to make the ip address of the DMZ port the default gateway for all hosts on the wifi guest VLAN.
The problem I have is that I have a couple servers behind the inside interface that have services available to the public Internet via a NAT address on the outside interface. I want the guests on the wifi VLAN to have the ability to access the servers on the inside interface using the public address as well, but have not been able to come up with a solution yet.

I need to configure my ASA 5520 version 7.3 firewall to translate our SMTP server residing in local LAN to use different IP address from the outside interface which is used by all other computers to access Internet.
Under NAT section, i have NATted this internal SMTP server with different IP address(eg x.x.x.1) and also translated the remaining IP addresses in the LAN to the outside interface(eg x.x.x.2)
my problem is, Whenever i check the header for message coming from the smtp server it shows that, the SMTP server is also translated by using the same outside interface public ip address(i.e x.x.x.2) which is used by other client machine to access internet instead of the x.x.x.1.
how i can get my SMTP server to use separate IP and avoid to be blacklisted by some domain.
I've recently upgraded my old firewall from a PIX to an ASA5505 and have been trying to match up the configuration settings to no avail. I have is that I can't ping the new firewall on it's inside interface, despite having "icmp permit any inside" in the running config. Secondly, the server I have on there ("Sar") can't connect out to the internet.I've included the ASA's running config incase anybody can see if something stands out. I have a feeling it's either not letting anything onto the inside interface, or there is no nat going on. Lastly (and possibly relevant), the firewall is actually going at the end of a vlan, which is different to the firewall's inside vlan number. I don't know if this is actually the problem because the server can't connect out even if connected directly into the firewall.
View 32 Replies View RelatedI have an ASA 5505 configured to get a DHCP'd IP address from the ISP on it's outside interface. The problem I am seeing is when the ISP renews their IP address, the ASA 5505 is still holding on to the old IP address information. I have to either manually renew the IP or reload the ASA. I have the potential of rolling out hundreds of these devices and I would not like my customers to have to reboot their ASA everytime the ISP's DHCP lease experies.

I dont think it's the ISP since I have another device connected also using dhcp to the same ISP and it doesnt renew itself, it's just the ASA. Rebooting it, makes it pick up an adress straight away. The interface seems to be up, the GUI just reports "no ip adress" and then the ASA get's a new IP after about 10-15 min without one. Pressing the renew IP adress button in the GUI throws an error.
