Cisco 2620 - cannot ping gateway from 2nd router

I have CCNA lab with 2 Cisco 2620s connected by 2 WIC-1DSU T1 cards and each with connected FastEthernet ports. The ports are as followed

Router 1:
FA0/0: 72.43.231.245 /24
S0/0: 10.10.20.1 /29

Router 2:
FA0/0: 192.168.25.1 /24
S0/0: 10.10.20.2 /29

The connection between the 2 routers is working  (I can ping all ports from inside each router, and I can ping all ports from my PC) however I am not able to ping the gateway or any external IP address from the PC, 2nd router, or using the serial port on the first router using extended ping. Any Help would be greatly appreciated

Here are the run configs

On Router 2

Change ip route 0.0.0.0 0.0.0.0 Serial0/0 10.10.20.1 to
ip route 0.0.0.0 0.0.0.0 Serial0/0

Thank you for the answer. I was able to determine the issue - "deny any" was set as first on my access-list. It is working correctly now.
