Hello! I have configured 1700 series router to forward workstation traffic through one port and the voice through another. The Configuration is pretty straight forward, but we experience a major problems. When the SIP phones plugged in to the switch with pass through to the computers, we loose connections to PBX or Internet and it's not consistent, it's flapping in uneven amount of time. I can work all day and then just stop working with no clear cause. It does happened when only phones are connected to integrated switch alone. Completely makes no sense. When this occurs i can go the router and can ping everhing but NAT translation is just stop working, which is the reson to lost connections. here is the config: service timestamps debug datetime msec service timestamps log datetime msec no service password-encryption ! hostname cartergeer ! boot-start-marker warm-reboot boot-end-marker ! no aaa new-model ! ! dot11 syslog ! ! ip cef no ip dhcp use vrf connected no ip dhcp conflict logging ip dhcp excluded-address 192.168.1.1 192.168.1.10 ! ip dhcp pool PC-SUBNET    import all    network 192.168.1.0 255.255.255.0    dns-server 7.228.35.42 7.228.37.195 8.8.8.8    domain-name greatbasin.net    default-router 192.168.1.1 ! ! ip domain name greatbasin.net ip name-server 7.228.35.42 ip name-server 7.228.37.195 ip name-server 8.8.8.8 ! multilink bundle-name authenticated ! ! ! ! archive   log config   hidekeys ! ! ! ! ! interface FastEthernet0 description WAN1 ip address 7.228.13.165 255.255.255.252 ip nat outside ip virtual-reassembly no ip mroute-cache duplex auto speed auto ! interface FastEthernet1 decription WAN2 ip address 7.228.13.169 255.255.255.252 ip nat outside ip virtual-reassembly no ip mroute-cache duplex auto speed auto ! interface FastEthernet2 ! interface FastEthernet3 ! interface FastEthernet4 ! interface FastEthernet5 ! interface FastEthernet6 ! interface FastEthernet7 ! interface FastEthernet8 ! interface FastEthernet9 ! interface Dot11Radio0 no ip address shutdown speed basic-1.0 basic-2.0 basic-5.5 6.0 9.0 basic-11.0 12.0 18.0 24.0 36.0 48.0 54.0 station-role root !         interface Dot11Radio1 no ip address shutdown speed basic-6.0 9.0 basic-12.0 18.0 basic-24.0 36.0 48.0 54.0 station-role root ! interface Vlan1 description LOCAL-LAN ip address 192.168.2.1 255.255.255.0 secondary ip address 192.168.1.1 255.255.255.0 ip nat inside ip virtual-reassembly ip policy route-map LAN-TO-WAN ! interface Async1 no ip address encapsulation slip ! no ip forward-protocol nd ip route 0.0.0.0 0.0.0.0 FastEthernet0 ip route 0.0.0.0 0.0.0.0 FastEthernet1 ! ! no ip http server no ip http secure-server ip nat inside source list 101 interface FastEthernet0 overload ip nat inside source list 102 interface FastEthernet1 overload ! access-list 101 permit ip 192.168.1.0 0.0.0.255 any access-list 102 permit ip 192.168.2.0 0.0.0.255 any ! ! ! route-map LAN-TO-WAN permit 10 description PC-SUBNET-NAT match ip address 101 set interface FastEthernet0 ! route-map LAN-TO-WAN permit 20 description VOICE-SUBNET-NAT match ip address 102 set interface FastEthernet1 ! ! !         ! control-plane ! ! line con 0 exec-timeout 0 0 logging synchronous line 1 modem InOut stopbits 1 speed 115200 flowcontrol hardware line aux 0 line vty 0 4 end ...

Currently we have  RV042G, which doesn't load-balancing automagically, but the problem is SIP which a nightmare with this type of load balancing, unfortunately this one doesn't have an ios so i cant tweak it to send sip traffic only thru one connection. We looking for the Small business IOS cable router, that will support routing maps. We have a 2 connection 1 is DSL and another is T1. T1 should be utilized strictly for voice SIP traffic, i only know how to accomplish that with ACL and routing-map. I'm considering Cisco 800 series but not sure if it supports rout-maps. Maybe there is another way and router to accomplish this. Any thought and sugesstions on this problem? Thank you. =) ... View more

Hello everyone, We have quite big wireless infrastructure that provides Internet for more then 100 customers. Please see the attachment for the map. - 1 Cisco 3600 router with 2 ports one F0/0 for the wireless backend and F0/1 for the fiberlink to outside world. - For all the connections we use public ip address, currently we use 192.168.0.0/23 (192.168 is not real) for the f0/0 all the access points and switch use range of 192.168.0.1-192.168.0.50 the rest is for connection are access points. - The AP we use is Ubiquity Networks as well as the clients. - All the AP that are on the picture are in the bridged mode. - All the client AP's that are connection to those AP are in router mode. - We give business customers another public subnet /30 and residential 192.168.88.0/24 and route it all the way to F0/0 192.168.0.1/23 as default gateway for the clients AP but for CPE they have to use second of /30 address to be able to access Internet. Example 10.0.1.0/30 (assume it's public) 10.0.1.1 is LAN interface for customers AP and 10.0.1.2 is for their router, so the default gateway is 10.0.1.1. 192.168.0.0/23 10.0.1.0/30 10.0.1.3/30 ..... 10.0.1.252/30 for individual 2 public address (1 for AP and one for customer router) Potential problems: Basicaly we have a big broadcast domain on all our AP of /23 networks, that brings another problem customers can talk to each other, since they being router all the way back to Cisco Router which will say "ah, it's has to go back to the same interface it came from", but since switches and bridges don't know how to route that particular subnet it's gonna be dropped. Im planing to redesign the network in efficient way, if possible without using another public subnet for the end customers since we already have /23 there,  there should be the way only use one public subnet for all. Of course bridging all to /23 instead of routing will eliminate the need for anther customer subnet but /23 broadcast domain is not really efficient. Im thinking to use inter-vlan routing (router on the stick) dividing /23 on the bunch of /30 address, but not really sure how to implement it on such a big scale with all those wireless bridges. I would love to hear some recommendation how to go about this, even with possible configs for Cisco router. Thanks a lot! ... View more

Hello, long story short: I need to monitor and identify the traffic on the WAN GigabitEthernet0/3 interface. Recently after some changes to our network we discovered that our traffic to outside world via this link is doubled from 150-200 to 350 MB/sec (we use MRTG for bandwidth), we suspect there are something looping in the network. That is why I want to trace what is going via Gig0/3 in and out (mostly out). What are the suggestions on how to trace down and identify the what causing such a big spike in the outbound bandwidth? While replication of the port seems to be a good tool Im not sure that any laptop with packet tracer can handle 300 mb/s of traffic. But, what are suggestions?
