"We will need to defend well away from home and hopefully set ourselves up," says Andy, who is hoping to be on club duty at the end of the month rather than being involved for Wales against Norway in Oslo on May 27th and against Canada in Wrexham on May 30th.
"We have only conceded one goal in four games so hopefully we will get that side of it right - and we have enough quality to score at the other end."
Andy has been involved in playoffs before - about 20 years ago.
"I was 18 and at Swansea with a final that was over two legs - it was very, very tense," he recalls.
"But we have a lot of experience in this squad."
Andy kept his place against Wigan on Sunday even though Tomas Repka was available again after a three match ban and he adds:
"I have settled down a little bit and am getting a partnership going.
"We have two massive games coming up now - and the fans deserve a trip to Cardiff.
"We are all looking forward to the playoffs; Ipswich are a quality side who get the ball down well and pass it, as we try to - and managed to do in the second half on Sunday."
Andy admits that he felt some sympathy for Wigan at the weekend, and says:
"Obviously Deano's goal there upset the odds a little bit but I am pleased for him.
"I do feel for them, though, because they thought they were there with two minutes to go because they had the message that Palace were losing.
"They made it difficult in the first half but we did better after that."
The draw put Crystal Palace back in the playoff picture - to the delight of Hayden Mullins' former team mates.
"We knew that Palace were losing at 1-0 but that was all," he says, "and we didn't want to do anyone any favours.
"I have been involved in the playoffs with Palace when one year we got beat and one year we went up - so I have seen both sides of it.
"We are confident because we are going into it with a record of not getting beaten for four or five games, and it was important for the run up not to get beaten."
As for the trip to Ipswich, Hayden adds:
"They are a very good side and I have a lot of respect for them.
"It would be a great end to a difficult season if we went up and would put this club where it belongs."
