Cisco Router cannot ping 1 IP address on network
I am setting up a cisco 891 router and 2960 switch. I am using router on a stick and have 2 vlans set up that are separate from our production network.
192.168.100.240 /24 (current production) fe8 interface
192.168.99.1 /24 gi0.1 vlan 99
172.24.25.1 /24 gi0.2 vlan 25
from either of the vlans, I can reach the internet and everything on the production network just fine, except for our mail server that is at 192.168.100.1, by ping or through the browser interface.
I can ping it from the router console login, but if I specify the source address as one of the sub-interface IP's, I get no reply. I can ping any of the other ip addresses with a source specified) on the .100 network, just not the 100.1. I cannot ping it from the switch console login with or without a source.
I can post more info from the running config if needed.
Thanks!

Are other devices on the .100.0 network able to ping that server?
Can you do a "route print" in the command prompt on that server?

In the process of making/documenting a network diagram to upload, I realized I had no static routes to my 2 new vlans set on the email server firewall (I already had them set up on the main firewall). I plugged them in and everything is working great now. thanks for the help!

The mail server uses a different internet connection, and its default gateway is 100.230 to get to a separate firewall.
In the production network, I have a static dns entry pointing mail.XXX.net to the 100.1 IP address, instead of having our internal users mail traffic go out to the internet and back into our network. I also cannot ping/access the email server by its external IP address.
The 100.0 network is not currently set up as a vlan on the router right now, as it is on a separate physical interface, but I plan to move it to a vlan in the future and put the connection between the firewall and the router on its own /32 network and separate physical interface.
I have a gateway of last resort of 0.0.0.0 0.0.0.0 192.168.100.254 set on the router.
