Good day all,
I have a cisco 2960 X with two vlans, vlan 1 and vlan 2. I have an ADSL router on port 23 (router ip 192.168.1.254)
interface Vlan1
ip address 192.168.1.251 255.255.255.0
ip helper-address 192.168.1.1
interface Vlan2
ip address 192.168.2.1 255.255.255.0
ip access-group 01 in
ip helper-address 192.168.1.1
sh ip default-gateway
192.168.1.251
sh ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
+ - replicated route, % - next hop override
Gateway of last resort is not set
192.168.1.0/24 is variably subnetted, 2 subnets, 2 masks
C 192.168.1.0/24 is directly connected, Vlan1
L 192.168.1.251/32 is directly connected, Vlan1
192.168.2.0/24 is variably subnetted, 2 subnets, 2 masks
C 192.168.2.0/24 is directly connected, Vlan2
L 192.168.2.1/32 is directly connected, Vlan2

Problem is I can't seem to connect both vlans to internet access, IP Route doesn't seem to work.
Any thoughts, I believe I am amiss by inch.
I am gracious for your input.

Can you ping the router IP ?
How did you put the default gateway
ip defaul-gateway or ip route 0.0.0.0 0.0.0.0 <router-ip>

You need to enable ip routing and then add a static default route: ip route 0.0.0.0 0.0.0.0 192.168.1.251.
The ip default-gateway command only works for the switch management plane, not for routing traffic.
