I have a Cisco ASA running 8.2.5 (yes I know its old) that we plan on decommissioning this year but unfortunately, we are a ways away from doing so. This has a site to site VPN tunnel to 4 locations, 1 is another ASA, 2 are Sonicwalls, and 1 is a Ju...
Hello I'm trying to fix an issue I'm seeing between a ASA a Sonicwall NSA. Both sides are reporting no proposal chosen and I believe the issue is a mismatch between the local and remote networks that are accessible. On the sonicwall I have the follo...
Hello I'm having some trouble getting two specific networks over a site to site VPN to talk properly. On the ASA network 10.0.4.0/24 needs to reach networks 10.34.0.0/16 and 172.18.5.0/24 which are on the Juniper SRX and visa versa. At the moment I ...
Hello I have an older ASA5520 in CA that has a L2L VPN to a Juniper SRX in NC. I am trying to get my network on vlan 10 labeled dmz1 in the 10.0.4.0/24 network to talk to a network in NC 10.34.0.0/16 but I can't seem to get them to talk. I have a n...
Hello, I am teaching a networking class with some old 2620XM routers, C3550, and C2960 switches. In the lab I have them create on SW1 an access port to Sw2 vlan 5 on both sides. Also on SW1 they create an interface vlan 5 and assigna 192.168.5.x /24...
Thanks for the update. Hmmm we seem to be getting close to the answer to the question “why does creating a second interface vlan break ping between devices” but I still don’t quite see why it breaks things.Oddly I just tried to rebuild this scenari...
Thanks for the reply. This explains how to fix it but not why the behavior happens. While in class I believe I found one possible explaination, but it doesn't quite work with what you found in the show ip int bri. But here it is anyways.

Thanks for the reply. I do understand that a trunk would save this, but since this is for a lab of how intervlan routing works, that would defeat the purpose. A trunk would allow all vlan 5 traffic to reach all other switches on vlan 5 and would no...
yes this is a layer 2 interface. So some more details.config example: Sw1interface vlan 5ip address 192.168.5.1 255.255.255.0no shutinterface vlan 10ip address 192.168.10.1 255.255.255.0no shut int fa0/10switchport mode accessswitchport access vlan ...
